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 tents, 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).
