The DWR treatment, windblocker technology and abrasion resistance provide protection against the elements and tough terrain. Stretch nylon patches on the knees and seat provide extra durability. The 3-layer stretch nylon hems feature a 20K-10K membrane for extra waterproof protection around your ankles. The fabric in these trousers is welded together using a revolutionary process called Ultrasonic bonding, reducing bulk and adding to your comfort. Scuff guards on the hem add extra protection from boots and bindings so they can last year after year. Finished with a stretch waistband for comfort and zipped hand, back and side pockets for safe storage, the Supervertigo 2.0 Pants for men are perfect for winter mountaineering and skiing.
