Insulated with ¾” thick polyurethane high density closed cellfoam, which makes it hard for air to be blown through. Lined with a leak proof, eco-friendlywelded TPU liner that has physical strength and elasticity, making it abrasion resistant. Our canvascoolers are most popular for boating, picnics, lunch use, and traveling.
