Dry. Q 2. 5-layer waterproofing keeps pouring rain at bay while allowing breathability so you don't get soaked from the inside out while tackling a tough trail, and stretch construction ensures mobility when you're scrambling over scree and pushing towards peaks. Zippered underarm vents quickly dispel excess heat when the humidity gets to be too much, pack-compatible hand pockets let you access trail snacks without stopping, and the structured, bonded hood brim keeps your view of the trail clear when the rain is coming down.
