Based on the wildly popular Big Bear from the ALPS OutdoorZ line, the Big Bear X Fanny Backpack is an upgrade in all facets of the design. Constructed using 1680D ballistic nylon and featuring Hypalon at the stress points, this pack is tough and durable. Featuring a hidden day pack that can be rolled into the lid of the lumbar pack, this pack is really two packs in one. A molded foam waist belt and removable, adjustable bow hanging hook round out the design on this very comfortable, versatile pack.
