These trousers are built from a nylon THERMOLITE fabric with a brushed interior for excellent heat regulation and breathability in chilly conditions. The Kevlar® knee patches with 4-way Lycra® stretch use a ripstop construction to protect against rocks when scrambling. And a DWR treatment adds durability and keeps out light rain. A pull-on-style stretch waistband with an adjustable drawcord ensures a snug fit. And reflective elements offer greater visibility on the mountain. Zipped hems with silicone grippers help your trousers stay in place too. For equal parts cold-weather protection and durability when climbing, opt for the Vertigo 2.0 Pants for men.
