If you hate the thought of exposing your gear to water, dust, sand, and zippers then Filson's dry duffel might be the bag for you. The pictured mid-size version is made of polyester coated in vinyl for complete weather protection, particularly during transport by pickup or boat. Or foot on days the bus douses you in puddled street muck instead of stopping to pick you up in the pouring rain. A roll top closures secures with a hook-and-loop tab for further protection from element invasion, and to eliminate zipper battles.
Filson rounds out their dry duffel with a pair of quick-dry webbing handles, adjustable side buckle straps, and radio-frequency-welded seams. The medium measures 21" high x 24" wide.
