The Insulated Classic 20oz is based on our classic stainless steel water bottle combined with Climate Lock™ double-wall vacuum insulation, keeping drinks hot for 20 hours and iced for 50 hours! Klean Coat™ powder coat finish is 4X more durable, chip-resistant and safe for people and planet.

Because stainless steel itself is safe, they don't need to coat the inside of the bottle with a plastic or epoxy lining, which is one of the main differences between a stainless steel Klean Kanteen and aluminum bottles.
