This water bottle is made with food-grade stainless steel for the body. It complies with FDA standards and is BPA free. The textured surface on the outside makes it easier to grip. The double wall vacuum insulation is designed for both icy and hot water. It comes with a leak-proof screw lid. You can sip or chug your beverage one-handed, even while doing yoga or at the gym. The fold-out integral loop makes it easy to carry or attach to a backpack or belt. It has a locking mechanism to prevent leaking and splashing when laid on its side, upside down, or even shaken. The vacuum insulated water bottle features a wide mouth, allowing you to fill it with full-size ice cubes and making it easier to clean. It fits nicely in car cup holders.
