The MEMBRANE sil line was developed with one goal in mind - create the lightest, most waterproof fabrics on the market.

Same silpoly benefits of lower water absorption (i.e. no sagging) and increased UV resistance, but in a waterproof textile that's 15-30% lighter than traditional lightweight coated nylon/polyester fabrics.

MEMBRANE Silpoly is the ultralight version of our silpoly line of ultralight coated materials. At a finished weight of just 0.93 oz/yd², it is the lightest waterproof polyester textile available. The material features the following:

Custom woven, high-thread count 15D polyester
Plain-weave construction
High-quality sil/PU coating on each side

MEMBRANE Silpoly is best for situations where you want the lightest possible waterproof fabric outside of Cuben Fiber. Lower water resistance than the PU4000 version, but ~15% lighter.

A premium material for all projects requiring an extremely lightweight, waterproof textile. Common applications include tarps, tents, ponchos, gear sacks, pack covers, etc.

*Note: this fabric is the exact same on each side. If seam sealing, we recommend using a 100% Silicone sealant such as Sil-Net.
