The ultralight and simple central vessel is built with 100% waterproof Dyneema® Composite Fabrics, with two outer side pockets constructed of Dyneema® Hardline to provide an extra line of defense against abrasion, and an external center mesh pocket to give visibility to the contents and dry out wet clothing as you go. For hikes measured more by changes in climate zones and geographical features than distance, the Junction offers the ultimate versatility required to meet those demands. The 2400 (40L) volume size is ideal for weekend or section hikes where frequent resupply points are available.
