What Our Gearhead(R) Experts Are Saying:"I use the Pursuit 15L Backpack for fast hikes and peak bagging-it's lightweight but doesn't skimp on function. The Continuous Fit harness keeps it close and stable, and I love how the compression system quickly adapts depending on how much gear I'm hauling."When our goals lie above the treeline, we grab the Black Diamond Pursuit 15L Backpack for fast-moving, summit-chasing days. This ultralight pack is built with the brand's Continuous Fit Harness, hugging the body for a close, dynamic fit that keeps up on scrambling routes and steep ridgelines. A breathable back panel manages moisture, while stretch shoulder pockets keep nutrition and essentials within easy reach. With a quick-pull compression system, we can shrink down the volume when the pack isn't fully loaded. An external hydration sleeve, dedicated trekking pole storage, and water-resistant zippered pockets round out a build designed to handle everything from sunrise starts to alpine speed missions. It's minimal, technical, and always ready for vertical gain.
