Mission Workshop offers two expandable pack models; the large Vandal and its medium brother, the Rambler. While they aren’t a ‘tactical’ company, their internal framed packs are pretty cool. Touted as weatherproof they feature an expandable main cargo compartment that can be configured for use as either a “roll topâ€, or a traditional “flap down†opening. Made in America with a lifetime warranty, the bags are offered in a variety of colors including a ‘digi-cam’ that looks mysteriously like Woodland MARPAT.
