Includes 100 fl. oz. reservoir, which resides within its own zippered, insulated sleeve that's easily accessed through the air-mesh back panel for quick refilling. Staying hydrated is easy, thanks to left- or right-side tube routing, tube clip at front and a high-flow, soft-tipped bite valve with twist closure. Large zippered main pocket is ideal for carrying a shell, food, pumps, bike tools and tubes. Expandable front stash pocket can be cinched down to secure bulky items; small zippered pocket with key clip and a small stash pocket on very front stow smaller necessities.
