  • This is the high water-resistance version of our  2nd generation 1.1 oz Silpoly line of coated materials. This fabric is coated with a silicone/PU layer on one side, then a multi-pass PU coating on the other to create a highly waterproof/non-breathable fabric.

    Same silpoly benefits of   lower water absorptionand   increased UV resistance, but with a much  higher waterproof rating. The PU4000 also has less bias stretch, making it easier to sew.

    Great for projects such as tent/shelter floors, ground sheets, tarps, ponchos, gear sacks, pack covers, or any application where lightweight, highly waterproof/windproof fabric is needed.

    *Note - shiny side is PU4000 and dull is sil/PU. If seam sealing this fabric, you will need a sealant intended for PU coated materials (e.g. Seam Grip).

Excellent product

Made a rectangular fly (tarp some call 'em!) out of the silpoly PU4000. Easy to work with. Have used it a couple of times now and very impressed. Very light (about just over 1/2 the weight of an old nylon fly about same size) and what I like best is 'no sag' when wet or at night or when cool. Just put it up, tension, and that's it! Awesome product. oh, and it dries very quickly - well hardly needs to, just a shake and wait a bit.

Thanks for the review Darrell. Enjoy!
Great service

The material arrived better than ordered. I accidentally ordered 6 yards when my project needed 7. I placed a second order for 1 yard and through email clarified that I needed 7 continuous yards. Thanks for all the help clearing up my mistake!
