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 ensures a snug fit. And the partial polyester lining works to wick sweat away. Adjustable hems with zipped gussets also help with shoe compatibility. For equal parts cold-weather protection and durability when climbing, opt for the Vertigo 2 Pants for women.
