More info

This is the waterproof version of our custom developed HyperD┬« line of lightweight diamond grid ripstop nylon. 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.

At a 1.6 oz base weight, HyperD┬« PU4000 offers increased durabilitylower stretch, and much higher waterproofness than our 1.1 oz Silpoly. 

Great for projects such as tent/shelter floors, ground sheets, tarps, ponchos, gear sacks, pack covers, or any application where midweight, 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).
