Macpac Sentinel 50
The Macpac Sentinel 50 is a fully featured alpine pack for hardcore use.
The Sentinel 50 follows in the Macpac tradition of designing functional and durable mountaineering packs that stand up to years of abuse. The primary fabric used is Macpac's own legendary Aztec fabric. Aztec is a proofed cotton textile that is incredibly durable and abrasion resistant. It's also very weather resistant.
