The compact and agile Lowe Alpine AirZone Active 18 is built for cool, dry comfort on strenuous day hikes. It uses an AirZone LT suspended mesh carry system with fast-wicking hip fins for maximum air circulation, even under heavy loads. Built with a lightweight spring steel frame for efficient load transfer, it provides extra hiking convenience thanks to its quick-stash front pocket, TipGripper walking pole loops, top tensioners, sternum strap and integrated rain cover. Though designed with hill walking and mountain hiking in mind, the hydration-compatible AirZone Active 18 is equally handy for short-haul travel and city trips. In addition to stretch mesh side pockets, useful everyday features include a key clip, a light loop, a zipped security pocket and a highly refined urban aesthetic.
