The Nano is thin and rides close to your body so you will never experience any sagging or shifting. It also has the new Badlands Airtrack suspension which will keep you cool and comfortable all day. If you look closely at the foam, it is perforated allowing air to freely transfer between you and the pack. You will never find that attention to detail on other brands.
