This water bottle is the best. It's a 40 oz wide-mouth bottle with a leakproof straw cap that's easy to use. Just open it up, add some ice, and flip it to drink. The insulated stainless steel keeps drinks cold for up to 24 hours.

The double-wall vacuum insulation keeps drinks hot or cold for hours. It's perfect for keeping your drinks cold all day.

And don't worry about leaks - the straw cap is leakproof when closed. You can just close it and toss it in your bag. The straw design makes it easy to sip with one hand, and the cap clicks shut to keep your drink sealed all day.

The stainless steel is durable and ensures your drinks taste pure, with no leftover flavors. Plus, it's easy to clean - just disassemble the straw lid and toss it in the dishwasher.
