ULTRASPIRE - Summit XT (Black)



The Summit XT is a minimalist multi-use 15-liter pack. This pack is built with an open-air mesh which provides comfort and is incredibly breathable. The XT buckle ensures the pack remains secured during difficult upper body movements. This pack utilizes a bi-directional buckle on the waist which leverages two contact points to ensure a stable ride. The Summit XT can carry a 2-liter reservoir. On the pack’s main compartment is a string compression which keeps the pack close to the body. The aluminum toggle buckle can be used to secure an ice axe or trekking poles. An added zippered compartment within the main compartment helps to keep valuables safe and secure. The front harness features our ErgoFit design. Bottle pockets added to the harness ensure this vest can carry over 3 liters of water. The main pack body is built using a combination of XT Fabric for durability at the stress points, and 30D high tenacity nylon ripstop which balances weight/durability in a functional way. One size fits most.
