The Mountainsmith Lariat 65 is a true workhorse in the All-Terrain line, sized for week-long backpacking trips with a detachable daypack for shorter excursions and summit pushes. Our unique U-shaped zippered access to main compartment enables fast packing and easy organization. This feature is also at the heart of the Lariat 65's ability to go from trail to adventure travel. Whether backpacking the Colorado Trail or some remote land, this versatile pack is at home from trail to hostel without compromising performance. The innovative ICS Cup™ (Illiac Crest Shelf) hipbelt transfers and locks the pack load onto the hips, the Delta Wing Compression system pull the load into the lumbar region and focuses on the Lumbar Control Point™ pad on the lower backpanel to fully secure the pack load against the user's major weight bearing point, the lumbar/sacrum region. All this while the Anvil Airway™ backpanel keeps you cool on the longest trail day.
