“I have only used my Amsterdam Heated Mittens 2.0
twice. Both times I was skiing in Colorado and the temperature was in the mid teens too and got up to about 20 degrees Fahrenheit. I set them on the medium heat setting and my hands stayed warm most of the time. I was afraid to set them on high, fearing the battery would wear down too fast. Nexts time, I will bring the extra batteries I got and keep them on high to see how fast the battery runs out. I like that the mittens are long enough you can just pull them up over the outside of your coat cuffs and don't have to worry about tucking them into your coat cuffs. I measured as the website instructions dictated and the fit was perfect. Only reason I put "very good" for heating performance is that I have used them only twice.”
“My hands are ALWAYS cold and these are the first pair of affordable mittens I've found that allow me to ski all day easily.
The instructions for fit were easy and they are the perfect size.
I can't recommend these enough for those that are (like me) super sensitive to the cold.”
