I have not had great experience with thermal coffee containers.  I have found that they tend to have a few problems in common.

1) They will be too large for my cup holder and this is a must as I spend a good of time on the road.

2) They leak when you take a sip and then you have an awkward stain across your attire and nobody likes this.

3) Lastly they tend not to keep my drinks warm or cold for longer than 30 mins. 

This was unfortunate because I really enjoy a good latte or cold tea on the road.  A friend of mine knew of this dilemma and suggested the Thermos brand.   I was hesitant but he mentioned to me how he has had his travel tumbler for nearly 8 years and was very happy with its constancy to keep his drinks cold or hot.  I looked online and saw that they boast that it will keep drinks hot for 3 hours or drinks cold for 6.  I was skeptical but deiced to purchase a 14oz travel tumbler.  I was pleasantly surprised that it really did keep my drinks piping hot for hours! If you’re a disbeliever like I was, I know that this travel mug will suit your needs. It did not break the bank @ a little under $20 offered on JL Hufford!
