The Lowe Alpine AirZone Active 22 is built for cool, dry comfort on fast-paced hiking trips. The suspended mesh back panel of the new AirZone LT carry system creates a reliable ventilation space between back and pack for the rapid dispersal of moisture at traditional high-sweat zones. Built from robust ripstop nylon with a HydroShield weatherproof coating, the hydration compatible AirZone Active 22 is also rich in hiking features. In addition to TipGripper walking pole attachments and a sternum strap with whistle, there are side and upper compression straps to keep your gear stable and under control. Stretch mesh side pockets and an easy-accessfront zone are great for quick-stash items and there’s also an integrated rain cover built into the base for when the weather turns.
