Why It Gets Our Seal of Approval
  • Double-wall vacuum insulation keeps contents cold for up to 9 hours or hot for up to 5 hours
  • Extremely durable 18/8 grade stainless steel
  • BPA-free, also free of lead and phthalates
  • Cool to the touch when filled with hot liquids, sweat-proof when filled with cold liquids
  • Rotating top design locks the sip hole into an open or closed position with ease
  • Closing mechanism clearly marks whether it is open or closed
  • Lid mechanism comes apart for easy cleaning

The Thermos King Travel Tumbler uses patented TherMax double wall insulation to keep your drink as hot or as cold as when you packed it. Just make what you love and it will stay hot all the way until your lunch break (or even later). Clever design uses a rotating sip cover that lets you know if it' s open or closed, which helps prevent accidental spills. Classic, 1950's-inspired design.

2.0 Great insulation, badly flaking coating

Comments about Product:

I received this Thermos mug as a gift a little over a year ago. I've been very satisfied with the insulation power and usually leak-free top (I've had a couple of small leaks, but I may have filled the cup a little past the max-fill line). The exterior coating, however, is unacceptable. The coating started to wear off of the edge below the top after only a short while, but it was fairly contained. Now, a large region at the top of the mug is flaking off. I can scrape the coating off with my fingernail with little effort. I find bits of the coating on other containers in my food bag, I find flakes on my fingers after holding the cup, etc. It's unacceptable, I shouldn't have to worry about ingesting whatever paint / coating Thermos used. I haven't been hard on this mug - always gentle hand washing, no harsh storage / use environment.

4.0 HOT! HOT! HOT!

Comments about Product:

Wow - this keeps my coffee very HOT for HOURS. I love it. The only drawback is that it has six parts to disassemble, clean and reassemble. Also, it's not dishwasher safe.

5.0 Finally!

Comments about Product:

The only thermal mug I've found that doesn't pick up residual odors or flavors. My coffee tastes like coffee -- hot, hot coffee! It's pricey but worth it, as I'm not buying coffee at work anymore, so the mug paid for itself relatively quickly. Great product!

4.0 Thermos King is always great

Comments about Product:

This is a great tumbler. I bought it for my husband, but once he adds his creamer he doesn't think there is enough room in the mug because the lid is deep. So now it's my mug and I love it.

5.0 My new favorite travel beverage containe

Comments about Product:

This is my new favorite travel mug. It looks good, fits perfectly into the cup holder in my car and keeps my coffee HOT. One day I filled it at 7:30 AM, but left it on the counter instead of taking it with me. When I returned, about six hours later, my coffee was still hot. Ten hours later it was still warm. I love it!
