The Osprey Aether 60 is our Best Buy winner in the backpack category. It is one of the highest rated packs, one of the lightest, and also one of the least expensive. Only the Gregory Baltoro 65 and Arcteryx Altra 65 scored higher. The Altra is a better pack for heavier loads but it is also $145 more expensive. The Baltoro 65 is also more comfortable with bigger loads but heavier. For lighter loads of 35 pounds or less it is hard to tell much difference in comfort between the Altra, Baltoro and Aether. So if you like to go fast and light like we do, then the Aether is certainly the best value in backpacks.
