The 3400 Porter Backpack is the most minimalist pack in Hyperlite Mountain Gear's ultralight collection. With a capacity of fifty liters, the Porter has enough space for weekend desert trips or day-long alpine adventures whether you're climbing ice or rock. Hyperlite Mountain Gear made this pack out of the same Dyneema fabric used in climbing gear for long-lasting durability without the weight. Unique to Hyperlite Mountan Gear, the Porter's Dyneema Hardline suspension system lines the shoulder straps, waist belt, and back panel in foam padding and spacer mesh for breathable comfort, and there are removable aluminum stays for stability when you need it. The Porter has a roll-top closure and taped seams for protection against wet weather and snowy grounds. There are also daisy chain attachments for ice axes and other climbing gear, as well as zippered pockets for valuables and electronics.
