The cork bottle sleeve transforms your everyday water bottle into a sauna-ready hydration essential. Designed to fit many 32 oz bottles with a 3.5-inch diameter (we recommend measu ring first). Cork is naturally heat-resistant, grippy, and sustainably harvested — making it the ideal material for high-temperature environments like saunas. Paired with a neoprene lining, the sleeve adds a meaningful layer of insulation and drop protection. Show more
