During any spring or fall mission, the Black Diamond Alpine Pants marry extreme durability with a highly breathable construction. Designed with a four-way stretch fabric, they can handle any on-route move, and their lightweight construction keeps sweaty high-output missions from getting out of hand. A DWR finish adds peace of mind during questionable weather windows. With a hem-cord adjust in the ankles and integrated, adjustable belt with low-profile belt loops, adjustability is paramount.
