Whether your first sip is in the kitchen, car, or campsite, the Flex Sip™ lets you enjoy your favorite brew leak-free.
Superb upgrade to their previous wide-mouth coffee lid. Keeps liquids warmer longer and easy to clean up.
Tight cap, which is also easy to take apart for washing.
Otherwise, top, but when the drink is low, the output weakens. You can shake and rotate the bottle until too much comes out at once.
Keeps the heat in well even when in the open position.
