I’m 65 and have a problem with cold fingers when skiing, even in moderate temperatures in the mid 20s. I have used a pair of heated gloves the last year and a half, but they recently quit working. Not good when they cost $450. So, I bought these gloves because they are rated to -20 degrees. I used them for the first time skiing yesterday in 10 degree, foggy weather. The gloves are big and bulky due to all the insulation. I’m thinking this is good. The mitt part of the glove kept my fingers toasty, but my index finger was frozen cold all day and my thumb was a little cold, but not like my index finger. I was a bit disappointed. The gloves are well made and a quality product, so hopefully will work better when temperatures return to more normal mid-20s for my area.
