The Contigo Purity Glass Water Bottle with Silicone Tethered Lid, 20 oz., is an ideal solution for those who prefer a plastic-free drinking experience. It's made of glass, stainless steel, and food-grade silicone. It features a leak-proof lid (when closed) and a wide-mouth design that allows for easy liquid intake. Plus, a nonslip silicone sleeve protects the glass bottle while adding a fashionable touch. For added convenience, all parts are top-rack dishwasher-safe.
