Magical Osprey Fit
Awesome design--breathable and comfortable. I use this on an almost daily basis, whether for bike commutes to work, long walks when I want to carry extra water/insulating layers/camera/etc, and even overnight backpacking excursions (this may seem crazy, but a 22 L pack is a fine amount of room for warm weather backpacking, especially if you're a smaller person and a minimalist packer). The frame is so well-designed the pack feels weightless and the sizing is spot-on for me (I'm about 5'4" and 110# and I have a Small). I don't use hydration bladders, but I love the big mesh pockets on both sides of the Stratos--excellent water bottle storage and access, compared to many packs which sport pockets that seem designed to fit only one particular brand of bottle. Bought this as a do-it-all replacement after my well-loved and well-traveled messenger bag was stolen, and in the time I've had it, the Osprey has done an exceptional job helping me overcome my loss!
