Ray-Way Tarp kit
“Simplifies camping and raises it to an art form.”

The Ray-Way Tarp is for anyone who would like to sleep warmer and more comfortably in the wilds. Our Tarp is simple in appearance, yet will outperform even the most sophisticated tents in a wide variety of weather and terrain, when used according to the instructions in our book "Trail Life." The tarp is about a fourth the weight of even the lighter tents, and offers at least twice the living space. And even though this tarp is open all around, it is probably warmer than the tent you are currently using. Why? Because of the tarp's superior ventilation. A tent traps moisture, and that moisture saps body heat.

Our Ray-Way Tarp comes in Kit form. Sewing this kit is not difficult. See Why Sew?

Also, to keep the insects away, you can sew our Net-Tent Kit, for use beneath your tarp.

Sewing Instruction Updates

Formerly, our Tarp and Net-Tent instructions were contanined in our "Tarp Book." But now that the book is between printings, our instructions come with the kits. For pitching instructions see our book Trail Life.

These kits reflect our own philosophy and practice of using only the finest and most appropriate materials available anywhere. Using these kits, while following our instructions, you will create a tarp and net-tent that are virtually identical to the ones we make and use.

Advantages of the kits

  • We have developed a process that makes our silicone nylon much more weatherproof. This process adds no appreciable weight, and is proprietary - meaning available only from us.
  • Our Kits will save you time searching for the fabrics, lines, cordlocks, reinforcement patches, and so forth.
  • Everything in our kits is exactly what you will need to make the tarp or net-tent.
  • Our kits will save you money. Why? Because profit is not our primary aim. Rather, it is to provide you with the best and most appropriate materials for sewing your own ray-way tarp and net-tent.
  • Contents of the Ray-Way Tarp Kit

    The Ray-Way Tarp Kit comes with full sewing instructions, and will make either a one-person tarp or a two-person tarp.

    The kit contains the following items:

    Tarp fabric: silicone-nylon

    The fabric we recommend for most camping situations is a lightweight silicone-nylon, sometimes called silicone-impregnated nylon.

    Our standard silicone-nylon is 1.37 oz/yd2. As with any fabric, this refers to the weight in ounces of one square yard. Ours is the lightest available anywhere.

    Note that certain companies sell what they call 1.1 oz/yd2 silicone-nylon. In truth, no such material exists. The 1.1 oz is a textile manufacturing denotation; in reference to the weight of the nylon before the silicone coating is added. Calling the finished product 1.1 oz silicone nylon is a ploy to make you believe they have a superior product.

    Some companies and fabric outlets sell what they sometimes call a "double-coated" silicone nylon. It weighs about 1.52 oz/yd2, which is substantially heavier than our silicone nylon, while being no more waterproof. In short, it offers no extra advantages.

    Silicone nylon is thinner than urethane-nylon, so it stretches more in high wind. And it requires more careful handling in the field.

    Nearly all coated nylons are flammable. However, many heath experts think that the fire-retardant chemicals often added to commercial backpacking tents can pose an even greater health hazard.

    Alternatively, we also sell Tarp Kits of urethane-coated nylon. See more info. Since both the nylon and coating are heavier than the silicone-nylon, the material stretches less. Urethane-nylon might be the preferred choice for someone who frequently camps in high winds. Also this material is more durable. The urethane-nylon tarp that Jenny and I used on our 1994 PCT hike is over fifteen years old and still in good shape; we continue to use it occasionally.

    With a urethane-nylon tarp, the shiny side is the coated side, and it goes toward the earth. The uncoated side goes toward the sky. This protects the coating from the sun's UV-b. This still leaves the uncoated side exposed, but since the material is about twice as sun-resistant as the coating, this seems to be the best compromise. Note: all silicone-nylons are also subject to sun deterioration.

    We offer our Net-Tent and Spitfire Floors in urethane-coated nylon. This material is more waterproof, more durable, and not a slippery as silicone, so you won't tend to slide down-hill on slightly sloped ground.

    Webbing

    The webbing contained in the tarp kit is the specific size and type we recommend for the pull loops. It has the optimum thickness and width, and the best flexibility providing the highest strength and best stowability, while still being as lightweight as possible.

    Guy lines

    We have carefully selected our ridge guys and corner guys for lightness of weight yet their very high margin of strength. Also, our lifter guys are a specialized ray-way flat line that has a subtle stiffness that greatly reduces tangles.

    Stowbag materials

    Our Tarp Kit also contains the fabric, drawstring cord, and cord locks needed to make a tarp stowbag and a stakes stowbag.

    Finished Size

    Not including the beaks, the two-person tarp shelters an area 106" long by 92" wide when pitched with a roof slope of 30º.

    In this configuration, note the size of the two foam pads, each measuring 20" wide by 72" long. This tarp offers outstanding coverage!

    The one-person tarp shelters the same length, and 75" wide. As an example, for someone 20" wide at the shoulders (which is my own measurement) this tarp would give them 27" of additional coverage to either side. This shelter would be more than three times their width!

    If you cannot find a camping place this wide, which would be very rare, simply pitch the tarp with a steeper slope to its roof.

    Finished Weights

    Our Tarp Kit will make either a two-person tarp, or a one-person tarp.

    A two-person Ray-Way Tarp made of our 1.37 oz/yd2 silicone-nylon weighs 14.86 oz, plus 1.9 oz for the lineset, plus the seam-sealing.

    A one-person Ray-Way Tarp made of our 1.37 oz/yd2 silicone-nylon weighs 11.89 oz, plus 1.9 oz for the lineset, plus the seam-sealing.

    Contents of the Net-Tent Kit

    The net-tent is a netting enclosure that clips very simply beneath the ray-way tarp.

    Our Ray-Way Net-Tent Kit comes with full sewing instructions, and will make either a one-person net-tent or a two-person model.

    The kit contains no-see-um netting for the roof, side walls, headwall and footwall; silicone or urethane nylon for the floor, and all the suspension lines, reinforcement material, cord locks and suspension hooks. Additionally, the kit contains enough fabric for making a net-tent stowbag.

    The cord locks included with this kit (for the adjustable suspension lines) are custom made expressly for Ray-Way Products to be small and lightweight.

    Size

    One-person: Floor 81" by 31", Height: 24"

    Two-person: Floor 81" by 49", Height: 30"

    * Note: We feel that our Net-Tent is plenty wide. But should you want to make it wider, you can. The materials that come with the Kit will make a 1-person or a 2-person. With these materials you can make a 1-person as wide as you desire. Or you can make a 2-person Net-Tent 12" wider than normal for the silicone floor, or 8" wider for the urethane floor.

    Weight

    The completed one-person Net-Tent with a silicone floor weighs only 9.0 ounces! The two-person Net-Tent is only a few ounces more.

    However, in most cases the Net-Tent would serve also as the groundsheet. So when figuring your load and adding the weight of the Net-Tent, you would subtract the weight of the groundsheet. The resulting increase is minimal.

    Note, too, that the Net-Tent can be used as a groundsheet - with or without the tarp - when the bugs are not a problem. Simply spread it on the ground, floor side down, fold the netting on top of the floor to keep the netting clean, and lay your insulating foam pad on the netting. This gives you an additional layer under your pad, for a little more comfort and warmth. This option can be especially attractive when carrying a minimal foam pad.

    As as option, we are offering our Net-Tent Kit with a urethane-coated nylon floor. This option replaces the silicone nylon fabric provided in the kit with urethane nylon instead. Please see our Order Form. Most commercially manufactured tent floors are made from a urethane-coated fabric. It is durable and not as slippery as the silicone nylon, but it weighs almost twice as much.

    If you find the silicone nylon floor slippery, you can do one of two modifications. 1: Sew stake loops at each of the four corners of the bathtub floor and carry two extra stakes for the uphill side. Leave the downhill loops un-staked to save weight. 2: Or replace the floor with urethane-coated nylon, available from us.

    Keeping the bugs out: Our Net-Tent comes without zippers, to save weight. To keep the bugs out, you simply tuck the netting headwall extension under the floor. You can make an even better seal by by placing the edge of the netting extension flush with the edge of the bathtub extension of the floor, and rolling them up a few times. Then you would place some weight (water bottles for example) on the roll to hold it in place. This method is very effective. But if camping in a place where the bugs are especially numerous, you might want to sleep in a Spitfire instead. The Spitfire has a set of zippers that close the door to make a better seal.


    Thread

    In addition to the kits, we are also selling what we consider to be the world's finest sewing thread. This thread is not included in our kits, but is a separate item listed on our order form.

    Discover the advantages of a Ray-Way Tarp for yourself.

    Many of the tarps shown on this page are pitched too low to the ground. On a no-wind night, or one with very little wind, the ridge of a two-person tarp should be 52" above the ground, and the ridge of a one-person tarp 44". Anything lower is inviting condensation to form under the tarp. And if very low, that condensation might drip onto the occupants.

    The tarp shown at right, as sewn by Mike G., UK, shows a proper low-lying pitch in stormy weather, which Mike says that night was. He says he and his children slept very comfortably. The low pitch helps block strong winds; and the winds, in turn, prevent condensation.

    Blast from the Past

    This photo was taken decades ago: in 1973 in the Holy Cross mountains of Colorado. The main attraction is not me, but the tarp of my design. Note the lifter patches and prototype beaks. The students and other instructors used polytarps, but my home-made tarp was nylon. The foam pad was a commercial item, open cell covered with nylon, and I slept with it oriented perpendicular to the ridge rather than parallel to it. The cotton shirt and blue jeans? Well, back then we did not have many alternatives. However as indicated by the smile, the camping was just as fun back then as it is today.



    Question: "Ray, Is there a difference in condensation with a tarp made of the urethane as opposed to silicon? I like the sound of the urethane being tougher but worry about condensation.? - Al H.

    A: Condensation is the tiny beads of water that form on a humid night. This is not the real problem for a camper. Rather, the problem is the increased moisture emitted by the sleeper in a tent. This is a vapor, so it permeates one’s insulating clothing and sleeping bag or quilt, and it absolutely sucks the heat out of them. Under a tarp, the vapor wafts away in the breeze, leaving the insulation dry. This is true whether it’s raining or not. And whether the ground is wet or not.

    Both the tent and tarp can form condensation, but it is only a tent that must be dried out during the day. The tarp works just a well, wet or dry.

    However, with a tent you are pretty much stuck with the condensation. With a tarp you have a excellent option. Simply raise the tarp several inches.

    In general, if your tarp is condensing, that simply means that you pitched it too low. Granted, there are situations where no matter how high, the tarp will condense; but in my experience these occasions are very rare. But under a tarp I have never had so much condensation that it drips on me. But then, I don’t pitch the tarp low, unless the wind is strong.

    The urethane and the silicone are pretty much the same as far as condensation is concerned. So is polyurethane sheeting and things like Gore-tex.

    But again, if one's tarp is condensing, that simply means that it is pitched too low.


    Question: "Are the kit tarps a catenary cut design?"

    A: Some tents benefit from a cat cut, but not our tarps. With some (not all) tents, a catenary cut evens the stress and reduces wrinkles. But with our tarps, the stress is already evenly distributed due to the stretch in the nylon, which easily conforms it to the catenary curved ridge. A cat cut would offer no advantages to our tarps. It would waste materials somewhat, and would make them much more difficult for the average home-sewing person to cut out and sew. Imagine drawing a curve on a piece of nylon nine feet in length and only 1.5" of curve at its mid-point. The average person could not achieve that with any degree of success. A computer laser cutter could, but the finished results would be no stronger and no better looking.


    Question: "I am wondering about using an iron on the tarp material" -L.G.

    A: The heat of a clothes iron, even at its lowest setting, would probably damage the nylon tarp fabric beyond all repair. After you have used the tarp a few times, the wrinkles will relax on their own, and will be much less noticeable.


    Question: "In reading the instructions in my Tarp Book (which came with my Ray-Way Tarp Kit) I see you request a flat-felled seam for the roof seam. My question is, if I offset the fabric ½ inch, won’t that make one side shorter than the other?

    A: According to our instructions, you offset one piece of fabric ½ inch, but then after sewing the first seam you fold (flat fell) the other piece ½ inch. So the finished seam comes out centered. Try it on two equally sizes scraps.

    "This last winter I made both a one person and a two person tarp and net tent set. I also made a one person tarp for a friend. It was a great project and they're wonderful pieces of equipment that I've used in both Colorado recreationally and in Montana as a ranger. My work pack is quite heavy so I'm always looking for ways to shave off a few pounds. Thanks for all your great ideas and books!" - Rachel J's. Home-made tarp and net-tent beneath the Three Apostles, Colorado.

    Comments

    "Used the tarp on a weekend scout camp in the high Wasatch Mountains. We experienced the first winter storm in the mountains. 1.57 inches of moisture in the form of rain, sleet, hail and eight inches of snow. I pitched the tarp using the two pole Ray-Way method. My tarp was one of three structures out of eight that did not sustain any damage and collapse from the wet snow. Throughout the night when the snow would build up, I'd bang the sides of the tarp with my hand and the snow would slip down to the ground. In the morning I had 18 inches of snow piled on each side of the tarp, but not a drop of water inside! If I had any questions about the design of the tarp, they were answered last Friday night / Saturday morning. PS. I don't know the speed of the wind, but it could be best described as whipping! PSS. I'm going to stop using a clove hitch on the stakes and start using the "Ray-Way butterfly quick release clove hitch." The wind tightened the clove hitches so tight that I could hardly loosen them in the morning." -John M. (Marc) K. Venture Crew 9112 Advisor, US.Army.Mil

    "Though we have never sewn anything before, we were able to (mostly) complete our RW tarp. We couldn't wait, and set it up in the back yard to see how it was going to look. Hey, just like the pictures! Maybe a little wrinkled but we'll fix that. Still need to sew in the lift patches and the accessory loops inside, but otherwise done. Not perfect, but still good. It weighs 14.7 oz on the digital postal scale in it's carry bag. Thanks for the great products and personalized service!" -George & Jalene H.

    "I made a tarp well over a year ago using "seconds" grade material to save a few bucks with the understanding that the material was a second only in color blemish, not water proofing. I used it through several minor rains and noticed what seemed like micro mini raindrops on my skin but there were no perceptible spots on my quilt. A couple of weeks ago I was in a good downpour that lasted well over an hour. Well, I had a steady fine mist coming through the tarp under its entire surface. It was enough that it quickly dampened my nylon pants and I ended up lying in my rain jacket with my quilt, in its trash bag, laying on my legs to keep them dry. If the weather were cooler this would have been quite a problem. Ray, in your Tarp Book you discourage the use of the “seconds” material and if I had read your book prior to making my tarp, I wouldn't now own a large rain sieve. Thanks for writing the book with its great instructions and for the great high quality kits that make the experience even easier." -Fred E.

    Reply: We are very sorry to hear about your tarp. That was wasted money and a lot of wasted sewing time and effort. Thanks for sharing your story, so that other people might learn from it.

    In our Tarp Book we discuss "seconds grade" silicone nylon as sold by other fabric outlets, and we describe how this is likely to leak during a rainstorm. However, our tests have since shown that even "first quality" silicone nylons sold by other companies are likely to pass a fine mist during a heavy rain. Our silicone nylon is proprietary, and much more weatherproof.

    "I completed sewing my new two-person tarp last night. What a wonderful shelter! And the experience of crafting it together, with practically no prior sewing experience, was very fulfilling and uplifting. It turned out quite well. What a delightful difference a lighter pack makes! I can focus on the beauty filling my soul rather than on my burden. I'm grateful that you have shared your vast experience with me through your books." -Ken

    "I finished my new tarp from your kit and it came together without a hitch. I was careful to read the instructions and understand the diagrams before I started, and then re-read them as I went along. The lack of waste was especially impressive because when I purchase my materials from separate sources, there is always more than is needed so I am left with unusable leftovers. With your kit, the only excess was the sil-nylon and that can be used for various stow sacks. The biggest challenge was my skill with the sewing machine and some of the seams do need improvement, but hey, I did it. To me, the stow sack construction was actually the most fun. I have made a myriad of stow sacks and was not sure where your design was leading to when I started. As it came together, WOW, I should have thought of that." -Fred E.

    "I just finished making my 2 person tarp from your kit. The time the kit saved me in gathering materials and the knowledge that I was using the best quality material available make it a real (and rare) value. The directions in the Tarp book were very clear and easy to understand once you start to pay close attention to all those important details that make the tarp such a precision tool to use in the out-of-doors. I just followed the directions and everything fit together like a puzzle. In all, it was a very enjoyable experience to make what will be my outside shelter for some time to come. It will be more enjoyable to use it, each day remembering that I made it with my own hands. Not directly related to sewing, I suggest at the end of your classes you suggest the students re-read Beyond Backpacking. I did and got a bunch more out of it, even though I had read it MANY times before." -Ed G.

    "I just retired after 30 years of teaching. My wife and I love to backpack, but we've done too many 50 lbs. packs. With the AT and many other adventures all ahead and the time to do it, your book on lightweight backpacking has been terrific. Last weekend we went out, stealth camped, carried only 18 lbs. (Still working on reducing more.) After a tremendous rainstorm one night, we were totally dry using the tarp. Some friends who had camped in their 3-season tent were soaked. I've ordered the net tent kit. Thanks for a new frame of reference." -Jim H.

    "We completed our Ray-Way Tarp and Net-Net and took it on our first adventure circumnavigating the Three Sisters. Both were fantastic as the bugs and the weather were severe. Thank you for sharing your experience and skills with the kits. We found the instructions and the materials to be the highest quality and the results are the best. On our first 4 day trip the bugs were out in force and we were extremely happy with how fast the system was to setup up. It took us a few nights to learn how high to pitch the tarp. We would have done better to read your instructions more carefully!!!! Nonetheless, they worked perfectly. On our last night we were caught by a huge thunder storm with 1/2 in hail and a flood of rain. Everything worked great as we quickly setup the Tarp, pushed our gear under it and then put up the Net-Tent finishing seconds before the sky fell on us in the form of heavy rain. Thanks again for your terrific designs. We are looking forward to your future inventions becoming available as kits." -Pat & Nola B.

    "I just wanted to say thanks for the great tarp design and kit. I finished the kit and took it on its first trip last weekend. The benefit in space and weight reduction in my pack were significant, and I had no difficulty setting the tarp up. It really took no longer to set up than my tent and fly. The instructions in your book are clear and well written for the novice. I avoided the temptation to take shortcuts, and the results were excellent. As an engineer in an aerospace firm, I fully appreciate well thought out lightweight design, and can see it throughout your products. I'll be ordering the quilt, and net tent kits in the near future in order to reap the full benefits." -Eric B.

    "I tried it out by sewing one of your stuff sacks as shown in your tarp book. Amazingly I was successful on the first try. Your instructions were easy to follow." -Scott S.

    "Thanks for everything. After you shipped the order Saturday it arrived Tuesday, it was amazing, I wasn't expecting it to come that fast. We have always been into hiking, but when we heard about your line of products we got your tarp and net kit and your two person quilt kit with Xtra layer and split kit along with stowbags. After we completed the tarp we couldn't wait for everything else so we went camping in the hill country of Texas with just that and plastic sheeting underneath as you said to do. We loved it! Thank you very much. What a great way to commune with nature. We have never used anything but a tent before and I was a little wary of being open to the elements, but it was great. Our dog, Saible absolutely loved the tarp as well because she could sense and hear everything around us and protect us in our "den". -Nina S.

    "Greetings from Holland. The picture was taken at dusk in the Eifel (Germany). You can see our tarp in the woods. When you look closely, in the Net tent is our Kelly green quilt. Emmy is sleeping under it, warm and comfortable despite to low temperature (2 C) that morning. We love the quilt and will take it with us on our PCT hike in about one month. We live in Rotterdam and the Eifel en Ardenne are excellent for training. We stay very close to the methods in the PCT Hikers Handbook. We feel very well prepared, thanks to that book. Thanks again for the Kits send to us! They made some rainy and cold winter nights, warm and refreshing behind the sewing machine. And even better, now we have self-made gear that we can use on our summer hike!" -Robert C.

    "Your kits are great! The tarp was my first sewing project. I made it primarily because I wanted to use it while hiking New Hampshire's Cohos Trail. I wanted to use your lightweight techniques to make it enjoyable. I figured spending some time constructing the tarp would teach me something about the spirit of the tarp itself. I also liked that you had thought out the entire processes and included all the materials. My biggest worry was that I'd screw it up so bad I'd have to abandon all sewing projects and use the poly tarp method. I used the Tarp Book and was actually surprised at how easy it was to follow the directions, despite how unnerving it was for a neophyte to approach a sewing machine. During the cutting phase I found myself making simple mistakes. "Measure twice, cut once" quote worked for me here. It was difficult for me to sew in a straight line, but eventually I learned to sew slower. Twice I had to remove stitches from about 4 inches of overlap where the beak fabric had crept under the seam. I was afraid that the pinholes would leak, but they didn't (at least not that I noticed) -- though a couple tropical depressions, no less. I eventually learned to continuously check that it wasn't bunching or folding under. A better sewing machine would have helped me, but I only had the newfangled el-cheapo Singer. Despite my initial floundering, the resulting tarp worked great! We had driving rain storms, and on another trip we survived a night which was punctuated by the remnants of hurricane Bonnie. I also made two quilts from your kits. The quilt kits were much easier for me to sew, but that's probably because of the experience I had by that time." -John R.

    "Hi Ray, Good weather finally coincided with time off and I was able to get an Antarctic photo for you. This one is just the tarp alone with Mt Erebus, the volcano upon whose flanks we reside. -Rachel J.


    Question: “I'm planning a December winter hike on the Long Trail in Vermont. Would your tarp kits be appropriate for this kind of winter backpacking?”

    Answer: Throwing oneself into a winter trip with unfamiliar gear could get a person into trouble. I have seen it happen far too many times - with tents mostly. A winter trip can be much more rewarding, granted, but also more unforgiving. Mistakes are inevitable while learning to use unfamiliar gear - be it a tent or a tarp. So I recommend making one's mistakes in summer time, and then using one's knowledge in winter.

    As such, I discourage using a tarp in winter if the person has not become familiar with its use in summer. The same holds true with a tent, stove, compass navigation, and all the rest.

    Another way to become familiar with the gear in winter is of course car camping. Pitch the tarp or tent near the car and enjoy a good night's rest while you let it snow. Then next time, pitch a ways further from the car, and so forth. A person might be happily surprised how fun this can be.
