Thanks to its expandable volume and dual-compartment design, the Airzone offers versatility and allows you to carry plenty of gear for a long backpacking trip or quick overnight winter hike.The Airzone's dual-compartment design consists of an easy-access front entry and lower entry with zip-out divider, which means you're able to organize your pack to separate clean from dirty clothes (unlike that pile of t-shirts on your floor), and access your gear quickly should you need snacks or an extra layer. Additionally, the side compression straps assist in managing your load, while the lash points, trekking pole or ice axe attachment loops, and bellow side pockets lend room for extra storage that can't be stuffed within the pack's confines.In keeping with the theme of adaptability and exploration, the Centro Airzone suspension system features an adjustable back length that encourages a fine-tuned fit. Not to mention, the Centro Airzone is equipped with a new cut-out space and less mesh than previous models, providing higher levels of breathability to reduce any swamp-like sensations from happening on your back. The suspension system also features an AdaptiveFit hip belt and harness, which assures fit and stability. Lastly, the Airzone is designed with an integrated rain cover, guaranteeing a safeguard for your loot in the event weather turns south.
