This is a 12oz cooler cup from Hydro Flask. It's a 2-way design that can be used as a can or bottle cooler, or as a 12-ounce beverage cup. The silicone sleeve can be attached to the top to secure bottles or cans, or to the bottom to prevent scratches and slipping when used as a beverage cup. Made with durable, rust-resistant 18/8 stainless steel, which is also used in tableware, and featuring a double-wall vacuum insulation, it prevents the transfer of external heat, keeping the contents at the desired temperature. You can enjoy a cold drink without chilling the glass, and it won't sweat, so coasters are unnecessary. It prevents flavor transfer, preserving the taste of your beverages. The exterior doesn't get hot, so you won't have to worry about it being too hot to hold.
