For weekend backpacking trips and carrying your camping supplies, a 35- to 50-liter bag is plenty. Anything over 50 liters of gear is overpacking — especially because most packs have straps to carry additional items, like your sleeping pad or tent, on the outside.

Osprey is pretty much the gold standard in packs. The new Atmos AG 50 is relatively lightweight (under 4.5 pounds), and it’s packed with features like compression straps, easy-access pockets, anti-gravity suspension systems that disperse weight evenly across your body (not your shoulders and back), foam-padded straps, and so much more.
