The largest of the AirZone Active backpacks has the same features as our smaller backpacks, but has a stronger hip belt. The hip belt is designed to take weight off the shoulders while keeping the backpack stable. It provides maximum comfort for all day carrying, even with heavier luggage. Convenient pockets on the hip belt let you stash extras like snacks, gloves or a compass within easy reach. The AirZone LT back system provides optimal air circulation to keep you cool and comfortable when the trail gets steep. Made of durable ripstop material with a waterproof HydroShield coating, the hydration system-compatible AirZone Active 26 also has a host of features useful for hiking in rough terrain. In addition to TipGripper hiking pole loops, it has compression straps to keep your gear secure and stable. The side and front mesh pockets made of stretch material are ideal for stowing wet gear or things that need to be quickly at hand. And if the weather changes, the integrated rain cover can be quickly pulled out of the backpack so you can continue your tour.
