Features

• Shoulder straps are linked to the other by the cable which helps maintain an even, balanced load across the shoulders.
• Thermoformed back panel is vented for enhanced air circulation.
• Removable, padded hipbelt has a floating, pass-through design that flexes smoothly and allows comfortable mobility in all directions.
• 4mm aluminum frame and framesheet offer stripped-down performance.

• Internal pocket holds hydration reservoir (sold separately) and provides hands-free drinking on the trail.
