Our Corkcicle 16 oz canteen is BPA free and crafted from stainless steel with proprietary triple insulation. The design is slip-proof, with a silicone bottom, easy-grip sides, and a screw-on cap.
Drinks stay ice-cold for up to 25 hours or hot for up to 12 without freezing or sweating. Add ice to your cold drink to extend the 25-hour threshold even longer.
