Big Agnes Prospector 50L

Your pack shouldn’t weigh more than the gear inside, that’s why we engineered the Big Agnes Prospector 50L pack, built in two sizes, men's medium and large, to ensure proper fit and ultralight comfort on the long haul. Featuring a compression molded back panel, contoured shoulder straps, foam padded hip belt, and equipped with a unique Hoist Compression system that pulls the load inward and upward for stability and comfort, this 50L pack include plenty of storage capacity and hydration compatibility for overnight trips. At Big Agnes, we’ve integrated our years of experience, ultralight recycled materials and technical features to deliver a fast and light pack for overnighters, thru hikers and anyone in between who sleeps and plays in the dirt.
