    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.

1.4 oz 10D Waterproof/Breathable

Thank you Joyce! Let us know if you have any questions about future projects, we're here to help!


Made rainpants. Indeed very breathable fabric and comfortable to wear, no stretch but light and soft enough to follow all moves. I used PU tape to tape the seams, worked well is and much cheaper then DCF tape. A 70/10 needle could not make it through the fabric, a 80/12 needle worked fine.

Thanks so much for your review Marieke! Rain pants are an awesome project for this fabric. We'd love to see photos of your creation! Be sure to tag us on social media!

I purchased the 1.4 oz 10D material to make a raincoat with a hood. I made the jacket large enough to wear a jacket underneath. Sewing this material was a little challenging until I put craft paper under the material to pull it through the machine. After that it worked like a charm. I used an iron on tape to seal the seams, which worked great as well. The jacket kept me dry while backpacking through very foggy, rainy conditions at 35 degrees. The only reason I gave it 4 stars was because of some puckering on the inside of the jacket in very wet conditions. It may have been due to the cold temperatures. But, overall the material held up well to two full days of wear with shoulder straps rubbing the material.

Hey Phil! Thanks for your review. We are glad the 1.4 oz 10D worked well for your jacket, even in cold conditions. The tread definitely makes a difference especially in rainy conditions. We recommend a 100% polyester thread since it has more resistance to moisture. Let us know if you have any questions about future projects, we're here to help!


This fabric was just what I needed to make over mitts for cold, wet running.

Thanks for your review Margie! Overmitts is a great projects to save your hands from cold and wet conditions! We'd love to see your project, be sure to tag us on social media!
