eVent fabrics’ DVStorm™ membrane technology comes to market in Spring ’15
 with new products from Rab® and Montane®

eVent fabrics – Outdoor Retailer Summer Market Booth MR150B – August 6-9, Salt Lake City, Utah, USA

eVent fabrics’ newest waterproof and air permeable membrane technology—called DVStorm™—makes its debut in Spring 2015 in new products from technical outdoor brands Montane® and Rab®.

DVStorm is the newest Direct Venting™ (DV) membrane from eVent fabrics, which introduced its original air permeable and waterproof ePTFE technology in 1999. Three-layer laminates made with the DVStorm membrane use 15-denier face fabrics and 10-denier backers, which result in lighter and softer finished fabrics for apparel and other uses.

Test results show that DVStorm fabrics are approximately 20% lighter and 15% more breathable than fabrics made with eVent’s original membrane. Internal test data shows the waterproof water column rating is 10 meters or greater, and breathability measures 31,000g/m2/24 hours using test method JIS 1099-B1. The high breathability of DVStorm fabrics helps enhance the comfort of rainwear used by alpinists, trekkers, cyclists and other active outdoor enthusiasts who generate body heat and moisture while facing moderate wet weather and conditions.

“We are very excited about the lighter weight and even more breathable DVStorm development from eVent fabrics,” said Tim Jasper, Head of Design at Rab. “Light weight and high performance are essential for the conditions in which our new Latok shelters and Muztag jacket will be put to the test.”

“At Montane we always strive to use the most innovative, lightweight and breathable waterproof fabric technologies available, to allow our athletes to go further and faster no matter the conditions,” said Paul Cosgrove, Brand Director at Montane. “By working directly with eVent we’ve been able to utilize the hyper breathable and super lightweight DVStorm fabric technology into our new Featherlite Shell Jacket, which will be ideal for lightweight, fast alpine activity.”

New Products using eVent DVStorm technology

For Spring ’15, Montane and Rab are introducing products using eVent DVStorm technology.

Rab Men’s Muztag Jacket

Rab Muztag Jacket

Rab is introducing the men’s and women’s Muztag Jacket, a light alpine shell with DVStorm technology. This versatile, streamlined jacket has a mid-range, regular fit that is contoured with room for movement. The jacket weighs an estimated 340 grams (12 oz.) for the men’s jacket and 285 grams (10 oz.) for the women’s jacket. Features include a helmet compatible, wired hood with roll down Velcro® tab, YKK Aquaguard® front and A-line chest pocket zippers.

Rab Latok Tents: Latok Mountain 3, Latok Mountain 2, Latok Summit

In 2015, Rab’s Latok series of tents will feature eVent DVStorm which are ideal for 2-3 people on high mountain expeditions, polar use, or summit bids on technical routes. The three tents take full advantage of light, waterproof eVent DVStorm fabric with single-layer engineering supported by internal poles, strong construction and secure pitching systems.

Rab Alpine Bivi

Rab Alpine Bivi

Rab’s Alpine Bivi takes full advantage of waterproof DVStorm technology, with essential features needed for a one-person, minimalist shelter. Lightweight fabric saves weight in the mummy-shaped design, and the basic zippered entry with external storm flap simplifies this packable, soloist shelter. Light eVent DVStorm fabric on top lets out heat and moisture and bathtub-design bottom of coated nylon is durable and snow worthy. Estimated weight is 470 grams (16.5 oz.) and packed size is 30 x 12 cm (12 x 5 in).

Montane Featherlite Shell Jacket

Montane® Featherlite™ Shell Jacket
Montane has pushed the boundaries of lightweight alpine garment design with the new Featherlite® Shell Jacket, weighing in at a mere 297.5 grams (10.5 oz.) for a men’s size medium. This fully featured mountain shell boasts an innovative articulated sleeve design to allow for unrestricted freedom of movement while keeping the jacket in place during big reaches. The lightweight innovation continues with a micro trim package, fully adjustable helmet compatible hood system, as well as YKK AquaGuard® zips throughout, two high level hand pockets and contrast coloured taped seams throughout to ensure full weather protection.

About eVent® membrane technology and eVent waterproof fabrics
eVent fabrics, introduced in 1999, were the first air permeable and waterproof performance textiles on the market. The patented Direct Venting™ technology in eVent waterproof fabrics has been lauded for its ability to ‘let the sweat out™’ and enhance the comfort of rainwear and footwear. The technology used in eVent membranes was invented in the 1990s to improve the pollutant-capturing performance of air filtration systems and give superior protection to industrial machinery. CLARCOR Industrial Air manufactures the eVent membranes, collaborating with worldwide suppliers to offer textiles to companies that create apparel, footwear, shelter and accessories for the outdoor sporting goods, military and professional markets.
