Review on Men'S & Women'S 3M Thinsulate Insulated Winter Ski Mittens OZERO Heated Glove Thermal For Snow Work by Mike Wieneke

I moved to the Chicago area and decided it would be a good idea to have some cold-weather, heavy duty mittens, for when I have to clear snow and the temps are single-digits or below. When these mittens arrived I thought they felt too thin and light to have good insulation. That 3M Thinsulate is awesome! These have been really great cold-weather mittens. They have an inner "glove" liner (individual finger sleeves inside the main mitten) to help add layers for warmth without adding bulk or weight. The leather in the "touch" areas is soft and pliable but tough, like leather. I've used them in weather as cold as -5f so far, and as long as I keep my hands busy, they stay plenty warm. If my hands are still, like when I'm pushing my snowblower for a long length of time, the cold does come through. They claim they are usable down to "-40." Um.that's a stretch. But they are warm enough for winter use, so long as you're south of the Yukon territory.
