The original AO canvas cooler series has been in the cooler game for over 30 years! Our canvas coolers have been a staple for our brand with good reason. Our canvas cooler's exterior is made from 600 denier polyester canvas, with a heavy duty backing for exterior strength, and a Scotch guard topcoat for UV protection. Insulated with ¾” thick polyurethane high density closed cell foam, which makes it hard for air to be blown through. Lined with a leak proof, eco-friendly welded TPU liner that has physical strength and elasticity, making it abrasion resistant. Our canvas coolers are most popular for boating, picnics, lunch use, and traveling.
