Filson Dry Duffle Bag
Most bags are can stand up to a little bad weather, but if your bag is going to be exposed to the elements — whether on a roof rack, in a pickup bed, or on the back of an ATV — you'd best get something a bit more rugged. Something like the Filson Dry Duffle Bag. Designed to stand up to the roughest of conditions, its made from vinyl-coated polyester, and features a roll top design with a hook-and-loop closure, quick-dry webbing handles, RF welded seams, adjustable buckle straps to cinch down on the sides, and a removable shoulder strap for easy carrying.
