The easy-to-use bumper on the bottom allows for a skid-proof grip that minimizes spills, while the rubberized finish makes the bottle look and feel soft to the touch. The 24-oz. portable size is a great fit for cup holders so you can take it with you throughout the day, and the vacuum-insulated stainless steel keeps your drinks cold for up to 18 hours so you have more time to enjoy the moment. Use without the straw to enjoy hot beverages for up to 6 hours, too. BPA-free, the lid, straw, and bumper are top-rack dishwasher-safe and the body is hand-wash only for easy cleaning.
