The MISSION DUFFELS' design is honed from MYSTERY RANCHs expertise in organized carry. The horseshoe-shaped zippered access allows easy access to the guts of the duffel. Rugged waterproof TPU coated 1000D nylon fabric provides ample water-resistance. For longevity of the waterproofing, the TPU treated side of the fabric faces the interior, eliminating sun exposure and scratches that could potentially break the waterproofing down. The reverse side of the fabric, on the exterior of the pack, provides a twill-weave look while thoroughly protecting your gear from the elements. These feature-filled duffels will quickly become your favorite travel companion.
