The Vario 50 makes the jump into serious expedition territory. It starts with 5,000 cubic inches of load-carrying capacity, a double-drawstring closure on the main pocket, and a lid system with double buckles for added security. Side zippers give you access to the middle of the main pocket for easy gear retrieval, and stretch side pockets keep odds and ends in reach. Constructed from revolutionary new KXO-50 fabric, the Vario 50 is an insanely tough, highly water-resistant pack that will carry massive amounts of equipment or meat with ease.
