The Kelty Cloud 5250 has aluminum stays and features a top-loading design. It also has removable pocket–a brilliant idea. When you don’t need the extra storage, lighten the load by removing all unneeded compartments. When you want the extras for a long hike or gear-intensive trip, reattach the pockets and move out with all the space you require. Bungee compression lets you contract the unused space to cinch the pack to its smallest size. Padded straps and a three-layer waist belt complete with stays make this a great, ultralight pack.
