Rab Airox 36L Backpack Ain't No Mountain High Enough The Airox pack uses a body-contouring suspended mesh panel that keeps the pack structure away from your back, letting air move freely so sweat has somewhere to go on steep, exposed terrain. The durable ripstop nylon handles the daily abuse of rocky trails and gear loops without adding unnecessary weight, and a reduced-profile chassis keeps the load centered and stable when the gradient tilts hard. For day hikes, hut-to-hut missions, or long summer approaches, it carries enough for a full day while staying organized and dialed. The perforated shoulder harness, lid pockets, front zip access, and built-in rain cover make it a complete do-everything pack rather than a bare-bones hauler. AEROFIT(TM) back system keeps air flowing between the pack and your back, cutting sweat buildup and heat on sustained climbs Shoulder straps with flask storage add breathability and keep nutrition and hydration within reach without stopping Plenty of pockets give fast access to layering pieces, maps, and snacks without unpacking the main body Hydration compatible sleeve supports hands-free drinking on the move without sacrificing main compartment volume All in the details, with bungee pole storage, rain cover, and compression straps handle the extras that come with full-day objectives in variable mountain weather140D Ripstop Nylon Construction (69% Recycled) keeps the pack light and durable while reducing the material footprint without sacrificing trail toughness | Rab | Airox 36L Backpack | Nylon
