I just can't find a pair of gloves that will keep my hands warm.

When winter weather hits us, I can prepare for my walks with the dog at night.  Hat, coat, scarf, boots, all no problem.  But I have never been able to find a pair of gloves that will keep my hands warm.

I have tried everything.  Work gloves, Thinsulate gloves, sheepskin gloves, barn gloves, ski gloves, thermal gloves and others.  Maybe it is just me.  But no matter what I buy, or how much I spend, the gloves are always a big FAIL for my outdoor adventures.

Any advice?
