Osprey Atmos 30 Backpack
When I need a daypack for a long day on the trail, this is the pack I grab. It has the full Airspeed suspension of the larger Atmos packs which means you can stuff it full of gear and be comfortable all day. It's got the same kangaroo pocket that the large Atmos packs have. I can shove a bear canister, sleeping bag, hammock, or mountain bike helmet in there no problem. The hip belt is wide and comfortable with two large zip pockets on it. The pack is a little on the heavy side due to the full Airspeed suspension, but that's a tradeoff I'll take any day. When I want to go fast and light I take a different backpack anyway, like my Stoke 19. The Atmos 30 is my Cadillac for a comfortable, enjoyable day on the trail.
