These are terrific. My husband has a blood problem that causes him to be cold all the time. He has to go to work at 1:30 a.m. and his car doesn't have a heater. His hands get so cold he can't work them. These are great and he is able to warm his hands for hours.
At $1 per warmer, these are a true bargin. Much less expensive than buying them at a ski shop or lodge. I use them all winter when skiing - they really work well.
