Imitating the charm of raw materials and natural fibers that can be found in the world's most picturesque forests, the Wood Collection, featured in a smooth matte finish, resembles mixed distressed woods. S'well bottles are beautifully crafted, composed of non-leaching and non-toxic 18/8 stainless steel. The bottles are triple-walled, leaving no condensation on the exterior. It keeps your drinks cold for 24 hours and hot for 12. Fits in a standard size cup holder. Size: 17 ounce, Color: Teakwood
