DIY Treecamp WPB Tarpsock (vid)


The waterproof/breathable tarpsock build of my DREAMS! Check out the super short video of the entire build and finished outcome:


Silnylon 1.35oz Seconds
60″ wide at $5.50 a yard (x) 3 yards (+) $8.67 shipping (=) $25.17

Noseeum Mess
$2.00 a yard (x) 3 yards (+) combined shipping (=) $6.00

Thread 100% polyester
500 yards (=) $4.38

Backpack Webbing
1 foot (=) free

TOTAL = $35.55
Finished Weight = 11.2 ounces

Material Dimensions

Silnylon 60″ x 9′ – yes this means you don’t even have to measure your silnylon, just order 3 yards!
Mesh 40″ wide from the head down to the 60″ mark, from there it tapers to 0″ wide. (See the picture below)

The Build

1. unpackage your new project!

2. trim off the fury ends from your 60″x108″ rectangle of silnylon

3. fold and sew all 4 edges

4. fold and sew 3 edges (both longest sides, and the foot end) a second time so that there are no unfinished edges showing.

5. fold the tarp in half, length wise (folded dimensions are 30″x108″)

6. sew the foot end of the tarp from the two edges up to the folded edge leaving a hole for your hammock anchor to pass through, I sewed on a small piece of webbing here for a tie out

7. cut the mesh to these dimensions:

8. roll and sew the edges once (excluding the head end)

9. roll and sew the longest sides a second time

10. line up the foot end (the end that comes to a point) with the folded-and-sewn end of the silnylon, sew the edges together

11. your tarp shoot now look like this:

…and this:

12. trim the mesh at the head end so it lines up with the silnylon, roll and sew the edge once

13. grab a piece of string or guyline, roll it into the edge, and sew into place

14. DONE! Unless…
15. if you are using a three point hammock you will want to sew two small tabs on the top of your tarp about 20″ apart (10″ out from the top center line on both sides). Unlike a two point hammock where you can cinch the tarp around the head end, a tarp for a three point hammock will creep down from the head towards the feet unless you use two little tabs to keep it tied up. Don’t forget to seal them to keep your tarp waterproof!



If anything is unclear in this tutorial just ask for some clarification in the comments below. Thank you and ENJOY!

  1. You or others that don’t want to DIY … should check out the Nube’ from Sierra Madre Research I have slept in it for 41 nights traveling Japan. It is similar to your construction but has better run off for rainy nights… and a few other bonuses! To watch Youtube of this product click here…

    I am just a customer that was lucky enough to get this product a bit early… but it is now available for sale off the shelf. This has been the best gear investment I have made, and want to share an alternative to making your own… and enjoying the great outdoors in comfort like what you have demonstrated! Great video’s… have watched many of them. And will be changing up first aid kit a bit… Thanks

  2. You Should design that thing so that when the weather is nice but the bugs are out you can rotate mesh up tarp down and see the stars. Great design btw.

      • Hands down I like your design better than others. Do you have a total weight? I backpack multiday trips with a 9 YO who packs his own gear so EVERY ounce counts. Will scale his down when we build it. Thanks for ask the great R&D and tutorials.

  3. This is a great idea for your rain fly but is there any other way to help cover where the anchor points are by the head end of the hammock to make sure that no water or insects get in during the night

  4. I tried to make this tarp but am having difficulty getting the head end to work right. I have cord running through the rim of the mosquito net but not through the silnylon. I have tried various configurations trying to feed the string through the webbing loops sewn onto the silnylon to make it work but it is sub-par. Could you provide some clarification on that end? Thanks.

    • Yes, the opening of this tarp is quite annoying. It would work well on a standard gathered-end hammock but since the opening has to cinch around two pieces of webbing that are 3 or 4 feet apart you need to get creative. Sew a tunnel for the cord on the lower half of the opening and thread the cord through it then make a tunnel on the top portion of the opening but don’t run the cord through it yet. Slide the tarpsock over your hammock and thread the cord on the INSIDE of your hammock’s left webbing (the silnylon will be on the outside of the webbing) and thread it through the top tunnel then pass it on the INSIDE of your hammock’s right webbing (again, the silnylon will be on the outside of the webbing) and tie it to the tail end of the cord (which is running through the lower tunnel. This will allow you to cinch the opening very tight but there will still be a small gap which will need to be covered with something if you don’t want mosquitoes to get you while you sleep. Ask me how I know that. You will have to do this everytime you setup your hammock which is why I just added a zipper to the side of the tarp for easy access and I left the tarpsock on permanently. Heck, you could even sew the gap shut if you added a zipper door on the side of the tarp. I hope that wasn’t too confusing!
