Sailmakers since 1880, the folks at Wm. J. Mills & Co. in Greenport, NY know a thing or two about strength and durability. Made from #8 waxed cotton duck canvas, the Shelter Island Duffel Bag is built for everyday rugged use. Approximately 17.5" long with an 11" interior diameter this is sized perfectly for use as a gym bag or an overnight excursion bag. The Shelter Island Duffel is versatile, waterproof, easy to clean, and almost as handsome as you are.
