The Klean Kanteen 20oz Insulated Bottle Classic Loop Cap is based on the classic Klean Kanteen water bottle combined with the Climate Lock double-wall insulation to achieve excellent thermal performance that keeps drinks hot up to 20 hours and iced for up to 50 hours! The Klean Coat feature is a new standard in durability and safety for not only people but also the planet! This coat finish is four times more durable to reduce impact and is also chip-resistant to keep up with your activities! The electropolished interior is a safe and non-toxic process that allows the rounded corners to be easily cleaned.
PLEASE NOTE: Brushed Stainless has no coating.
