The Roc Blanc Jacket is our most technical and durable men's shell jacket. Made in waterproof, windproof, breathable 3-layer Gore-Tex® Pro and designed for the most extreme outdoor environments, it was developed in collaboration with Tierra's test team of mountain professionals. The result is so robust that it’s employed as workwear by everyone from alpine guides to Himalayan Sherpas to the Swedish Mountain Rescue unit.
Three-layer Gore-Tex® Pro is that company’s most weatherproof and durable laminate, comprising an outer fabric, intermediate membrane, and inner fabric (backing). The outer layer is extremely tough polyamide, the microporous middle membrane does the miraculous job of preventing liquid water from penetrating while simultaneously releasing water vapour formed from sweat, and is protected by a ripstop polyamide inner fabric.
The Roc Blanc is packed with thoughtful features that serve a clear purpose: the adjustable hood can accommodate a helmet; recessed ventilation zips are easily accessed and operated; a snap closure allows the waterproof two-way front zip to be used as additional ventilation even with a climbing harness on; and the bottom drawstring is easily adjusted with one hand.
