Pack It Up

Perfect for those fast and light overnight missions, the Big Agnes Prospector 50L pack combines capacity with comfort. Ready when you are, this 50L pack features a compression molded back panel and shaped shoulder straps to keep your back happy, and a foam padded hip belt to take the load off. The Hoist Compression system pulls the weight inward and upward for those long hikes, while the storage and hydration compartments can hold enough for the sunset to sundown days. Between the ultralight fabric and enough bells and whistles to hold your essentials, the Prospector 50L will give you one less excuse to have a heavy pack.
