The Insulated Coffee/Tea Flask is a double-wall stainless steel vacuum insulated bottle from MIRA Brands. It is free of BPA and Phthalates and claims to keep drinks cold up to 24 hours and hot up to 12 hours.
This bottle is an 11-ounce size, so it's smaller than a normal coffee mug but that makes it great for travel and on-the-go. It has a screw-on cover similar to a thermos, and it doesn't leak at all. The outside of the bottle is a nice white matte finish and doesn't sweat or radiate any heat or cold from inside the bottle so you can have your hand around it even filled with steaming hot liquid.
I wanted to see if it really did keep beverages hot for a long time, so I filled it up with almost-boiling water, and sealed it shut. Keep in mind, I only opened it during the times I checked it, so I wasn't constantly opening to take sips which would cool off the liquid faster. Here are the results:
45 minutes - Scalding
2.5 hours - Burning
4 hours - Hot
6 hours - Hot
8 hours - Still Hot!!
I couldn't believe that after 8 hours - a full day at work - the water still hurt when I put my finger in it for the test. It wasn't even "just warm" but actually still hot. Again, this is after keeping it sealed most of the time and also starting out with really hot liquid, but this just proves how well the insulation works on this flask. It is definitely a great travel flask for coffee, tea, or water. It's easy to throw in a bag or purse and doesn't leak. Highly recommended (just know that it is smaller than a normal mug.)
