At just over 30 liters this Boundary is one of the largest in Granite Gear's new line of Barrier backpacks. It makes excellent use of this space through it's multi-compartment design, including a protective barrier stash pocket, a Gear-Tec laptop sleeve and a convenient multi-pocket organizer. It has two large stretch mesh hydration pockets, a daisy chain loop, and convenient stash straps located on the bottom of the pack. The Boundary has a raised back panel with lumbar support and hideaway hip belt, as well as a breathable, load absorbing shoulder harness.
