Our Neoprene Water Bottle Koozie - Retro Gray fits up to 24 oz. water bottles, and stretches to fit snug. Keeps your water cool, 'cause nobody likes a hot water bottle. Comfortable handle made from 1" webbing strap makes your water bottle feel like a super lightweight, super refreshing mug of watery goodness. Snap hook on top of handle strap allows you to hook your koozie easily to the outside of your DeckBagZ SUP deck bag. Exactly the same as our smaller water bottle koozie, but fits 24 oz. sport bottles.
