The Black Diamond Pursuit 15 Backpack is a summit pack for fast and light pursuits. Move fast to the top of the mountain with a pack that can handle high alpine scrambles. It won't weigh you down, and hugs the body with 'wing' construction to prevent unwanted movement while remaining totally comfortable. Stash your trekking poles when not in use, enjoy quick-access storage with a single zip pocket and three stretch pockets on the shoulders, and a Quick Pull Compression System adjusts the volume with ease.
