Zoku have recently launched a sleek line of vacuum insulated stainless steel bottles. The good looking and functional vacuum bottle makes sure your cold beverages will stay cool for up to 70 hours. Hot beverages will also keep their heat for up to 15 hours without losing steam. Designed to take a hit, this double-walled bottle is made of heavy gauge 18/8 stainless steel, and all the corners are rounded and smooth, making it easy to slip into an elasticized backpack punch or a cup holder. Another great detail is the removable paracord lanyard, making it easy to carry. Available in 12oz, 18oz or 25oz, and in several colors.
