Stone Glacier's Talus 6900 is a purpose-built hunting backpack that offers increased access and organization while remaining as lightweight as possible. The main bag of the Talus 6900 is 6400 cubic inches with an additional 500 cubic inches of storage space in the lid, bringing the total interior carrying capacity to 6900 cubic inches. Internal carrying capacity can be further increased by 2500+ cubic inches with the use of a load shelf, bringing the overall internal volume to an impressive 8000+ cubic inches. Alternatively, the Talus 6900 can be converted into the lighter, more compact "bivy-mode" with 4000 cubic inches of carrying capacity for shorter day trips. The main center zipper provides access to the entire contents of the main bag and use heavy duty YKK #10 zippers that can stand up to a lifetime of hard use. The Talus 6900 also features 4 external side pockets. Two of the side pockets are zippered and run almost the entire length of the backpack, directly beneath them are two open pockets. This configuration allows longer pieces of gear such as rifles, tripods, and spotting scopes to be secured in the longer zippered pockets and the bottom pockets to serve as a catch. NOTE: This pack is the BAG ONLY. A Stone Glacier frame is required. Stone Glacier Sky Talus 6900 Bag Only w/Lid Ranger OSFM 50026-RG-OSFM
