    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).
