This extended-trip pack sports an active suspension system that flexes and retracts as you move, offering enhanced range of motion and load support on long distance treks.

• Patent-pending ergoACTIV hipbelt, breathable back panel and soft, 3D mesh lining on hipbelt and shoulder straps provide topnotch support and comfort
• SwingArm shoulder straps move in concert with a hikers stride or a climbers reach by sliding through the bottom of the pack with a low-friction cable and housing
• Shoulder straps are linked to the other by the cable which helps maintain an even, balanced load across the shoulders
• An ideal blend of volume, comfort and mobility lets you bring everything you need without slowing you down or limiting your range of motion
• Top-loading pack body features a floating lid to accommodate large or small loads; giant U-shape front-panel zipper offers easy access

• Hipbelt stash pocket, side stretch pockets and large zippered front pocket offer plenty of storage for water bottles, snacks and other essentials
