i did not buy this through backcountry, but i've written some reviews today and thinking of my favorite gear, this one is up there. day hikes, fieldwork, long mtb rides this pack excels. pedaling up long climbs, i stick my helmet on the handy helmet mount and it doesn't move.
my other day packs are really neglected. opsrey packs are not only designed with alot of thought, they feel great. i own the Exos and Aether, both excellent and comfortable. like the aether, this pack comfortably holds weight when you've over packed. i would go with one size down for my uses. i need to stop buying packs.
