What Our Gearhead(R) Experts Are Saying:"I wear these any time I'm heading into mixed terrain-steep trails, scrambling, even light alpine missions. They breathe well, stretch easily, and the fabric feels tough enough to handle rock edges and rough bushwhacks. I really like how the waistband stays comfortable under a pack hip belt, and the DWR finish does a great job shedding light moisture. They've become my go-to mountain pants because they just move the way I need them to."We trust the Patagonia Terravia Alpine Pants when our days lead us across rugged trails, high ridgelines, and steep stretches of rock.
