The silicone case is designed to fit snugly around the base of the stainless steel water bottle, providing durable protection against dents, scratches, and everyday wear. Made from high-quality silicone, BPA-free and food-safe, it absorbs shocks and prevents loud noises when placing your bottle on hard surfaces. Compatible with all DOZZE Kids, Cruiser, and Voyager water bottles. Not compatible with Adventurer bottles, other DOZZE mugs, or other brands.
