The use of neoprene (wetsuit material) creates superior Custom Beverage Insulator, very durable and machine washable. Custom Beverage Insulator come in over a dozen different colors and are available in three different styles. The Can Cooler is produced from 5mm neoprene with a glued and stitched side seam and a non-skid, vented bottom. A wet suit for your bottle; the Bottle Suit is produced from 3mm neoprene with a double stitched zipper and pull ring. Please compare the construction of our bottle suits and can coolers to any competition. The Pocket Coolie is produced from 3mm neoprene. We use a zig-zag side stitch instead of a straight stitch so that the pocket coolie lays flat seam-on-seam and so that there is no extra material inside. Better quality at the same price as the competition’s cheapo foam!
