You can pack an extra 10 liters in the Lowe Alpine AirZone Centro 35 Plus Pack, which means its possible to fit your sleeping bag, small tent, stove, and food for a quick overnight in the backcountry. Lowe Alpine structured a cross-venting back and shoulder strap to minimize the amount of contact the AirZone Centro 35 Plus has with your back. This equals more airflow and less back sweat. Adjust the torso length and stash extra layers in the expandable front pocket. Unzip the side of the AirZone Centro 35 Plus to grab an otherwise-buried snack.
