Show off your brew and your brand with a custom Zipper Bottle Coolie from Boelter Beverage. Made from your choice of neoprene or a 100% open-cell material, each coolie offers maximum water control and easily stretches to fit different bottle shapes.

Neoprene and open cell information: Neoprene is a closed-cell, flexible rubber material that repels water and enjoys great insulation qualities. Generally speaking, neoprene items have a high perceived value due to the dense, yet soft, nature of the product. Open cell foam, however, absorbs water. The ability to absorb condensation from cans and bottles is one of the benefits this product affords when used as a beverage insulator. The foam is made from 100% polyester which results in much lower costs. Open cell foam does exhibit a certain amount of stretch, but its qualities are not generally viewed to be as long lasting as neoprene.
