Advanced Mountaineering Pack

Tackle summit pushes, long‐range patrols, or back-country bug-outs with our Advanced Mountaineering Pack. A ladder-adjustable torso harness and removable kidney belt spread the weight, while a fully padded lumbar panel keeps miles painless. Twin zip-close side pockets accept hydration bladders or radios and feed through ambidextrous ports, so you stay wired and watered on the move. Inside, a cavernous 4,016 cu-in main compartment cinches tight around your load, backed by dual mesh organizers for fast gear ID. Storm flap, built-in rain fly, and four external compression straps lockdown the kit when weather turns ugly. Rugged MOLLE fields plus top and side carry handles round out this mission-ready 66-liter hauler.
