Because it's made from hygienic, easy-to-clean stainless steel, the Klean Kanteen 20oz Insulated Cup lets you enjoy coffee that doesn't taste like chili or a smoothie that isn't tinged with hints of pesto pasta. The cup's high-performance vacuum design insulates hot beverages for up to six hours and cold beverages up to 24 hours, so you can enjoy hot chocolate on the ski lift or a cold beer at the trailhead after a hike.
