Crafted from the same high quality stainless steel as Tumbler, now available in a modern, wine glass-inspired silhouette. Stemless keeps your beverages cold for 9 hours and hot for 3. Stays cold even longer with drinks containing ice — even out in the sun. With its easy-grip sides, no-slip bottom and shatterproof, drink-through lid, you’ll enjoy stylish, spill-free sipping wherever, whenever.
