Specially made from food-grade stainless steel, the insulated tumbler is durable, easy to wash, and unbreakable. Electro-polished on the inside to ensure your cups remain rust-free, and colored powder-coated finish on the outside to make it super easy-grip. The shape is tapered and designed to perfectly fit in vehicle cup holders.

The tumbler comes with a sliding lid for spill-proof and reusable straw to help you stay neat. The wide mouth opening allows easy washing and quick filling. What's more, our tumblers use a sweat-free design, making sure it never leaves a spot and you never burn yourself again!

The ergonomic design allows one hand to use double-layer insulated water cups. The proper diameter allows it to be carried in a variety of ways, such as a standard bicycle bottle holder/cage, an adult backpack with external pockets, or a car cup holder.
