    Waterproof/Breathable (aka WPB) fabric is exactly what the name implies - both waterproof AND breathable. To achieve this, WPB fabric uses a specially formulated laminate film that is highly resistant to water droplet penetration (i.e. rain) while also allowing moisture vapor (i.e. sweat) to pass through and escape.

    Ultralight. Our 10 Denier WPB is the result of 8 months of development, testing, and pushing limits. While the even the lightest WPB currently comes in at over 2 oz, our 10D WPB breaks the mold with a finished weight of just 1.4 oz.

    Performance. With waterproofness and breathability rivaling or besting the name brands such as Gore-Tex and eVent (see full lab test data), you don't compromise on performance. Go lighter and be more comfortable doing it.

    The combination of waterproofness, breathability, and weight make this material excel in ultralight, high-performance rainwear. This variant is a 2.5 layer ultralight WPB, so it's best used in applications where you want the lightest weight and best performance possible, but not necessarily the highest durability.

    Typical applications include jackets, over mittens, gaiters, pants, ponchos, bivy shells, and more.


    * Taping - For seam sealing, we recommend using our Cuben Fiber repair tape, which sticks quite well to the PU laminate. Seam-Grip can also be used on the PU laminate side, but is a bit messier and leaves a not so clean finish. For bonding layers (joints, seams, etc), we recommend using our double-sided Cuben Fiber adhesive tape.

    * Cleaning - To ensure proper function of your WPB fabric, it is VERY important to keep it clean on both the inside (laminate) and face (10D ripstop nylon). We recommend wiping with a damp cloth periodically to remove dirt, oils, etc that build up over time. You can also purchase a product such as ReviveX Pro Cleaner for prep.

    * DWR maintenance - Another key to proper function is periodic DWR maintenance on the face material (10D ripstop nylon). Although we use one of the highest quality 80/20 DWR formulations, deterioration does occur over time. We highly recommend the purchase and use of a DWR restorer such as ReviveX Durable Waterproofing spray.

definitely waterproof

Thanks Susan! Let us know if we can help with anything in the future.

Nice fabric arrived quickly

Even to the other side of the world. Good fabric, very lightweight. My second order of this fabric, first I made a lightweight bivibag, DCF bottom and 10D waterproof breathable on the top. Also a very light pair of over trousers with full leg zips. Time will tell if the overtrou are durable enough. Definitely no scrub bashing! Next is a lightweight jacket for ski touring. The fabric is the right weight for these projects, but it would be good if you could offer a bit heavier, more durable breathable, waterproof fabric as well.

It sounds like you've made some awesome projects Ian! We'd love to see photos of your creations, be sure to tag us on social media!

1.4oz 10D waterproof/breathable material

This material is very light. I used it to make some rain pants. In limited testing they have been very water resistant. As expected, the material is a little fragile. I particularly had issues with seam sealant. Even after drying for a day or more, the material would stick t the sealant and then delaminate (Sealing, as suggested, on the inside.) When light weight is an important factor, definitely take a look at this material.

1.4 oz 10D WPB is great for a lightweight rain pants. Seam grip would be the best seam sealer for this material, if you're still having issues feel free to reach out to our support team to see how we can help. support@ripstopbytheroll.com

Holy crap

Double sided tape ftw. Otherwise this fabric is magic and you will end up with extra inch's as you go

Thanks so much for taking the time to leave us a review! You can do some pretty cool things with the 1.4 oz 10D WPB! Happy Making!
