    The 2nd generation of our silicone double coated 1.1 oz polyester ripstop (silpoly). This fabric is coated with a silicone/PU layer on each side and is waterproof/non-breathable.

    In addition to excellent waterproof/windproof characteristics, Silpoly offers lower water absorption and increased UV resistance compared to Silnylon. Particularly useful in outdoor applications to minimize sag/stretch when wet and color fade over time. 

    Great for projects such as tarps, tents, ponchos, gear sacks, pack covers, or any application where durable waterproof/windproof fabric is needed.

    NOTE - Colors with a reduced price of $5.25 /yd are being phased out of inventory. Once sold out, they will not be restocked.

I love it!

I use Polysil to protect the insides of the dog beds I make and as a third layer in jackets to have comfy windbreakers. Lots of uses for it!

That is a great idea Laura! Thanks for leaving us a review. What lucky dogs to have custom dog beds!

Silpoly fabric is the best

Lightweight, sews well, when seams treated with silicone sealer was absolutely waterproof.

Thanks for your review, Paloma! We're glad that you found a fabric you love working with. There are so many things you can do with the 1.1 oz Silpoly!

Great fabric

I purchased the silpoly as part of the winter tarp kit. The fabric is really easy to work with and is really good at handling the rain storms. It is lighter weight without breaking the bank.

Thanks for leaving us a review Timothy! We're glad the 1.1 oz Silpoly foots the bill for your Winter Tarp! We'd love to see photos of your creation, be sure to tag us on social media!

Scott Thomas
1.1 oz Silpoly

I like this material. I made a tarp with the membrane Silpoly and I loved it, but it was a little bit fragile (at least for my gear). I am hoping that this will be slightly tougher, but I'll still be careful with it. I was wondering if it would be bulkier and heavier feeling, but so far I can't tell the difference and I almost think it is packing into the stuff sack better than my first tarp (maybe because fabric is brand new and not exposed to outside yet?). Good stuff.

Thanks for your review Scott! We're glad to hear you're loving the 1.1 Silpoly for your new tarp. MEMBRANE Silpoly is much more delicate of a fabric. If you're harder on your gear, this is a gear choice. Be sure to share photos with us on social media, we'd love to see your creation!
