The Black Diamond Trail Vista 20 Backpack is a lightweight pack for the trail. When headed out for the day, bring only what you need in this sleek daypack. The harness features a Slide-Fit adjustment system, dialing in the torso length for the best fit possible. While the majority of your gear is easily housed in the main compartment, you can easily stash a jacket in the front stretch pocket, water bottles in the side stretch pockets, and small items in the zippered or stretch hipbelt pockets. Bringing Z-poles along? The bungees on the shoulder straps allow you to go hands-free whenever you desire.
