Stone Glacier delivers the ultimate minimalist multi-day backpack with the Solo 3600. The main compartment features 3600 cubic inches, but this can be further increased by 2500+ cubic inches with the use of a load shelf, bringing the overall internal volume to an impressive 6000+ cubic inches. This provides more than enough space for food, additional layers, downed game, and other gear/accessories. The contents of the main pocket are accessible with a full top panel zip, and a built-in differential cut spotting scope pocket to create more room in the bag for gear. NOTE: This pack is the BAG ONLY. A Stone Glacier frame is required. Stone Glacier Solo 3600 Bag Only Ranger OSFM 50056-RG-OSFM
