  • The MEMBRANEsil 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 MEMBRANE silpoly line of ultralight coated materials. At a finished weight of just 0.93 oz/yd 2, 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

Great service - Fast shipping

Super materials and DIY kits. Fast shipping.


What can I say? The product was exactly as described with a great price and great customer service (as always). I finished my tarp and got it up in the yard to test it before the local forecast called for rain. After two days of constant soaking, my gear was bone dry underneath. Thanks!

My First Order - more on the way...

Fantastic service. Many thanks.


Light and strong, though I weighed my piece at 1.0 osy, against a catolog finished weight of 0.93 osy.

Extremely Lightweight and waterproof- but slippery to work with

This is a very lightweight material with a relatively high waterproof index. I am using it to construct a fitted tarp/ rain cover/ sock for my bridge hammocks. The fabric is very slippery to handle so be prepared to have weights available to hold down the fabric while you mark your pattern on it. Also, you will find it helpful to use some sort of water-based kids glue stick to glue your seams together/ in place before stitching them. I am not sure how the heck you would managethis fabric without some glue.
