I bought this for day hikes especially for my epic 11 hour day hike summiting Mt. Katahdin in northern Maine. It fit so much, could hardly believe it was only a 20L pack. I LOVE the trampoline back, helps to keep you cooler. It held up really well especially considering I slid down many rock faces dragging the pack and there's really no wear to show. Highly adjustable straps and very comfortable for long durations. I'm a 5'9" 170lb male with a longer torso. Only problem I have is that the side pocket zippers are hard to close when wearing it, maybe it's just my short arms. Highly recommended!!
