Made for the miles between the trailhead and the truck, the Chamber gives framed packs a clean, flat stash point right where you need it—top of the bag, against the frame. Reach it by feel, grab the small essentials, and get back to it. A secure zip keeps contents contained over rough terrain. Choose 525d Pack Cloth for classic durability or X-Pac laminate for added structure and weather resistance. Included with select framed packs; this page is for an extra or replacement.
