When you need your gear to stay absolutely dry, there's just no compromise to be had. That's when the new Filson Medium Dry Duffel gets its chance to shine. Filson started construction of this beast by using burly 18oz vinyl coated polyester for a durable, waterproof outer. The rolltop closure ensures that nothing unwanted gets into, or out of, your bag. You have your choice of carrying options with standard handles that clasp in the middle, or an adjustable and removable shoulder strap, so you can really haul some loads around.
