Take this 40 oz insulated water bottle with you to a high-intensity workout or on an extra-long commute to keep your drink cold for hours.

Super Capacity & Long-Lasting Temperature Control: Stay refreshed with fewer refills—keeps drinks ​​cold for 34 hours​​ and ​​hot for 10 hours thanks to triple-wall vacuum insulation. The ​​slim base fits most car cup holders​​, while the ​​ergonomic handle​​ ensures easy carrying to work, the gym, or on trips
Advanced 2-in-1 Leakproof Lid: Switch between ​​smooth sipping (straw mode)​​ and ​​quick gulps (chug mode)​​ with our ​​patented screw-on lid​​—engineered to be ​​pop-off proof​​ with a ​​thickened silicone seal​​ for ​​100% leak resistance​​. The ​​360° rotatable lid​​ works for both left- and right-handed users
Complete Accessories for Leakproof Cup: Dust-proof straw cap keeps the straw clean wherever you go. Soft silicone straw tip​​ comfortable drinking at any angle. The largest straw allows you to enjoy your drinks and the straw brush is good for cleaning the straw. For the narrow base, we have customized a scratch-resistant and non-slip silicone boot
Eco-Friendly & Durable Stainless Steel​​: Made with ​​90% recycled BPA-free 18/8 stainless steel​​, this tumbler uses ​​weld-free construction​​ for superior durability and taste preservation. Ditch single-use plastics with a ​​lifetime-worthy​​ reusable cup that’s built to last
Dishwasher Safe & Lifetime Warranty​​: Cleaning your tumbler and lid couldn’t be easier, just pop them into the dishwasher—no stains or odors. And we promised to provide rugged, capable drink-ware built to last a lifetime
Customers find the tumbler to be of good quality, with positive feedback about its temperature retention, keeping drinks cold all day and holding cold water for two days. Moreover, the cup is leak-proof with no spills reported, and customers appreciate its ice retention, with ice cubes not melting for many hours. They like its vibrant color and size, with one customer noting it’s perfect for staying hydrated at work. However, the durability and lid functionality receive negative feedback, with reports of the plastic lid cracking and breaking, and the lid being extremely hard to get off.
