The kinto travel mug is a great every-day companion. First, it's an insulating mug that keeps hot things hot and cold things cold, though its most distinguishing characteristic is its clever 3-piece design. Most bottles have just a body and a lid, but the kinto mug has a intermediate piece that threads onto both the base and the lid that ensures only liquid make it through -- just the right amount. This helps it pass the the car back-seat test, which anyone who has used a naglene widemouth understands at a deep level. Additionally, it makes drinking tea a breeze ensuring no tea-bag make it's way through.
