Thermos DF2170 24-Ounce Briefcase Bottle

At first I loved this thermos for the size and ease of cleaning. But everytime I use it I love it more. It keeps coffee hot for hours. Over 7 hours after filling this thermos with coffee, it was still hot enough to burn my tongue. It also works great with cold liquids. I had ice water in it one afternoon and the *next evening* when I went to open and clean my thermos, there was still ice! I was amazed. I recommend this product to anyone. :-)

Everyday I used to take a cuisinart mug with coffee along with me on my way to school. Having to lug around my large bookbag, computer, and sometimes my digital camera, carrying an easy to spill coffee mug was no easy task. Not to mention I'd finish the whole thing before I ever finished my train ride. Now I can just throw the briefcase mug into my bookbag, and have no worries of spilling. Coffee stays warm for a ridiculously long time. I've cut bag on buying dunkin donuts coffee everyday, to almost never. This thing is the best investment ever. Also, it's sleek, the cheapest I could find for the size, and also keeps my iced tea cold on warmer days. Highly recommended.

My favorite for summer. Stays cold for 24 hours or more. Not just for briefcase. Nice size; I replaced my 16 oz. Fish, travel, whatever you want. Thermos is the best.
