    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 absorption and 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).

Great for tent tubs

I have made a few free standing tents over the last 2 years and I found out silnylon is a slip and slide when used as a tent floor. This Silpoly PU4000 has enough urethane to create some traction and still stay pretty light. I just wish RSBTR would update their projects page so the DIY community can continue to share and inspire

Thank for your review David! That is a great idea for a project. We are working on a new space for makers to share projects, stay tuned! We'd love to see photos of your project, here is a link if you'd like to share! https://forms.gle/erH82vVyNZF8UPao8

Second Tarp

The Silpoly PU4000 is perfect for my tarp use! Easy to work with and is nice and lightweight. Will be putting it to the test this June on an 8 day trip to the Golden Trout Wilderness area.
The folks at RBTR got my order to me in good condition, with reasonable shipping and in a timely manner. I live in Hawaii so thats a big plus.

Thanks for your review Doug! The 1.1 oz Silpoly PU4000 is awesome for tarps. We'd love to see photos of your creation, here is link to upload photos if you'd like to share! https://forms.gle/9J1eCPhQq88yjxaa7
