Solis heated mittens - I was able to test them a couple of times on the slope while downhills skiing. I am one that my finger get frozen pretty quick normally. This is the reason i purchase these mittens. I was a bit worry since these are somewhat expensive . But I had enough of freezing my fingers while skiing. Well they do what their suppose to do . They did keep my finger warm at minus 15c. I used the middle setting and they were still working after 3 hours. They instructions said that they could last longer at that setting. I don’t know since I stop before the batteries ran down of juice. Charging is very simple with the magnetic connection. Time will tell about reliability. All and all I like them.

Confortable -

merveilleux pour les mains - Très chaude et confortable, j'adore les porter pour mes activités extérieures
