S'well is a multi-tasking bottle that's designed to be hardy enough for backpacking and sophisticated enough for the boardroom. The double-walled, vacuum-sealed stainless steel vessel keeps liquids cold for 24 hours and hot for up to 12 hours. Its mouth is wide enough to accommodate ice cubes, while the base has been carefully considered to fit perfectly in a standard car cup holder. Plus a portion of all proceeds are donated to charitable causes including Drink Up, American Forest, and Wateraid. 17 oz. capacity. Hand wash recommended.
