The Gregory Deva shines in its ability to carry large, heavy loads with surprising comfort and stability. This burly backpack is built to endure the elements — with incredibly durable materials and zippers used in its construction. The shoulder straps are wide on this pack, and more suited for an athletic build than a petite frame. The Deva provides excellent ventilation against the back, with an airflow design that opposes the natural arch the back, creating a space for venting. Like the Arc'teryx Bora AR 61, the Deva utilizes a hip stabilizing system that hinges with the body's movement, allowing the shoulder straps and weight distribution to remain steady.
The pack is heavy, but in recent models, Gregory seems to have slimmed it down to a slightly more manageable weight. Similar to the Osprey Ariel and Arc'teryx Bora, the backpack features a removable top lid design that allows for use as a daypack. This is a convenient option when planning for side trips or day hikes from camp while on a multi-day trip in the backcountry.
