The technology is microscopic. The difference is huge.

eVent Air Permeable Technology


The critical difference between our air permeable technology and traditional waterproof/breathable fabrics is the billions of microscopic pores built into our proprietary membrane that work instantly to vent water vapor (sweat) that builds up inside your apparel and footwear when you perform.


We call this Direct Venting™ technology, and unlike other technologies, it doesn't need to get wet to work. It’s a 'dry system' that allows eVent fabrics to be fully waterproof and fully breathable – keeping you dry and comfortable in the widest range of temperatures and conditions.

Direct Venting™ technology is engineered to keep you in the ‘dry zone’ – a steady state of temperature and humidity that reduces the wild swings our bodies go through to stay in balance during physical exertion.


The result is that you’ll spend more time performing at your best and less time fussing with your gear. And when conditions are bad, that can make all the difference.

eVent BIO Technology


A greener all-weather alternative. Our bio-based membrane reduces our impact on the planet without sacrificing performance. This light, tough and flexible membrane is paired with recycled face fabrics and backers and treated with C0 DWR to keep you dry while reducing your carbon footprint.


eVent BIO sustainable membrane technology repels rain, wind and snow while still offering a high MVTR (moisture vapor transfer rate). Sweat and body heat can easily escape no matter the location or activity, so you can stay cool, dry and comfortable any time of year.

Science is on our side.

Trust data more than marketing? eVent fabrics have been extensively tested in the lab, and the results speak for themselves.
