This member of Mountainsmith’s All-Terrain series is a bit more sleek and agile, and is perfect for a vertical ascent, yet has the same versatility as the other packs in this line and can be used for more relaxing outdoor activities as well. The body of the pack is constructed of tough, weather-tested 420d Velocity nylon with 840d Ballistic fabric reinforcements to keep fastener attachments and other stress-points from fraying. Designed especially for women, features include a detachable lid that converts into a lumbar daypack, a sleeping-bag compartment and quick release compression straps hardware for your pad, two water bottle pockets, and two hydration pack exit ports.
