What every best Travel Mugs has:
- Excellent heat retention.
- Leak-proof seals.
- One-hand usability.
The Zojirushi Stainless Mug SM-SA offers just about everything you could ask for in a travel mug. It earns top marks for heat retention in professional tests, keeping hot water at a reasonable drinking temperature for hours. Its locking lid is virtually leakproof, no matter how you bounce the mug around, yet opens easily with the touch of a button when you want a drink. It's also lightweight and easy to clean (though it's not dishwasher-safe).
The Contigo West Loop Stainless Steel Tea Infuser converts the well-reviewed Contigo Autoseal West Loop Travel Mug (Est. $18) into an on-the-go teapot. Although it hasn't been professionally reviewed, owners at Amazon.com say the infuser is simple to use and gives them good control over the brewing process. The drip cup that holds the infuser after removal is a handy feature. Just be careful not to burn yourself when removing it.
If you need a travel mug you can reheat in the microwave, users say the Lenox Travel Mug is your best bet. Its simple, double-walled ceramic construction protects your hands from overheating and keeps hot drinks at a reasonable temperature. It's also surprisingly durable and very easy to clean (though putting it in the dishwasher isn't recommended). However, it's smaller than most travel mugs, and its silicone lid doesn't seal to prevent splashes or spills.
