The Sky Archer 6400 was designed with minimalism in mind, while still offering plenty of storage and convenient features. The main bag boasts 5,900 cubic inches of storage, and a hydration-compatible lid brings the total storage capacity to 6,400 cubic inches. Despite this immense amount of space, the bag itself weighs less than three pounds. The backpack also includes a spotting scope pocket, an 8-inch zippered pocket, and a 14-inch side stretch pocket for extra layers or a tripod.
