The Hudson Sutler 18 can soft cooler duffle bag is built around a half inch of insulation and a durable welded waterproof liner (normally used for life rafts) to keep your road sodas and Rosé ice cold regardless of where your travels take you, or for how long. Constructed with our hard wearing 18 oz canvas with a reinforced bottom and heavy weight cotton webbing handles. The rust proof resin zipper and flip top access make bringing this on the beach a no brainer. 18 beers? 6 bottles of wine? No problem.
