The Lowe Alpine AirZone Centro 35 Pack stores a waterproof jacket and pants, snacks for the entire day, maps, your GPS, and an emergency shelter when youre hiking in areas with unpredictable weather. Since you want your back to remain as sweat-free as possible, Lowe Alpine made the AirZone Centro 35 with a back panel that minimizes contact without sacrificing stability. Dont feel like digging through the top of this daypack to find sunscreen? Use the side entry zipper instead. An included rain cover keeps the AirZone Centro Pack dry during storms, a front pocket holds an extra layer, and the adjustable torso length keeps the fit comfortable for a day on the trail.
