3.3 oz Ventek™ 30 WPB

The result of over a year of development, testing, and pushing limits, Ventek is our custom designed, high-performance WPB fabric line.

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.

3.3 oz Ventek 30 is a 3-layer WPB fabric designed to balance weight and durability while maintaining performance (waterproofness and breathability) that rivals big names like Gore-Tex and eVent.

Great for a wide range of applications such as jackets, over mittens, gaiters, pants, ponchos, bivy shells, and more.

3.3 oz Ventak WPB is awesome stuff!

This fabric is great at keeping the rain out! I’m on my 5th rain jacket made so far and love how easy this is to work with. It’s lightweight, soft and breathable and helps fight the wind while keeping you dry. Paired with a tricot seam tape this fabric becomes truly watertight. And the best part is having it custom printed in the custom colors and patterns. Cant wait to finish this one and get started on the next! Thanks Ripstopbytheroll!

That sounds so epic! We would love to see photos of some of your rain jacket creations. Here is a link if you'd like to share any photos with us. https://forms.gle/WY88JMN8bbx2o1EC9
