Keep your beverage of choice frosty for hours in our stainless steel insulated wine tumbler. Double wall vacuum construction keeps your drink cold (or hot) for up to 4 hours. The powder-coated slip-free exterior makes it easy to hold. 12 ounce capacity is equal to 2 standard wine pours (but who’s counting?). The tumbler includes a BPA-free clear plastic lid with a straw hole for easy sipping. Made with high quality 18/8 grade stainless steel, this tumbler is pretty indestructible – which makes it perfect for boat life!
