With a flexible yet supportive BioSync design, side strap compression system, and a slew of handy pockets, the Gregory Maya 16 Backpack is ideal for full day hikes or epic all mountain bike rides. The Maya's BioSync suspension system allows the pack to move with your body in motion and keeps the pack centered on your back. Side compression straps secure the load so it doesn't shift around inside the pack. The pack's hydration tube management system keeps the drinking tube within easy reach, so you don't have to divert your attention to take a drink. Dual waist belt pockets and side pockets make it easy to access the things that you need to get to in a hurry, like your camera or a snack. The Gregory Maya 16 fits a two liter hydration reservoir, which is enough for a day hike or a long cross country mountain bike ride.
