Details Lowe Alpine AirZone Active 18L Rucksack The perfect backpack for hazy days on the hill, the AirZone Active 18 is a lightweight, well ventilated daypack designed to keep you cool on day hikes. It uses an AirZone LT suspended mesh carry system with anti-barrel plates and fast-wicking hip fins, for maximum air circulation, even under heavy load. Built with a lightweight spring steel frame for efficient load transfer, it also offers a quick-stash front pocket, double TipGripper walking pole attachments, top tensioners, a sternum strap with whistle and a rain cover inside the base. Although these features are designed with hill walking and mountain hiking in mind, the new hydration-compatible AirZone Active backpack is equally effective for work and travel. In addition to stretch mesh side pockets, user-friendly everyday necessities include a key clip, a light loop, a zipped security pocket and a refined new commute-ready aesthetic.
