The RotoGlide hipbelt rotates side-to-side and glides up and down for a more natural stride that reduces chafing and improves balance. GridLock shoulder straps adjust both in width and height for a precision fit. The highly durable pack body is made from 420d and 630d nylon fabrics, and is capped with weatherproof AC² fabric in areas exposed to rain or snow.
