This backpack is new with tag. It’s super lightweight but still offers a fully framed structure, durability, ventilation, full suspension system, and all the features and attachments you may need up in the mountains in any season. 30L Sized right for ultralight overnights and extended day trips, the Aerios 30 goes where you want to go and holds exactly what you need. Hydration compatible, the 30L main compartment handles trail essentials and camp gear, and the breathable AeroForm back panel, padded hipbelt, and adjustable harness combine for a comfortable carry. Multiple external pockets are secure and accessible, and the fabric’s liquid crystal ripstop provides excellent durability for minimal weight.
