I'm a Wisconsin resident. The winters are cool to cold (ex. today it's supposed to be mid-30s with 20+ mph wind, and two weeks ago it was below zero w/wind). How would these hold up?

not that warm,somehow wind resistant,but not that warm when it goes down 32,you might want to use a liner,u use 'em with a smartwool liner,and ufff! this babys are warm like that! but not alone

Live in the Boston area where it's very windy and very cold in the winter.These gloves are terrific as they block out the winds even when temps drop below freezing! But once the temp goes down to the teens to near zero Celsius, the warmth is diminished. For the most part, these gloves will keep you warm.Mind you... the gloves are not waterproof so when it gets wet (i.e. slush conditions), the wind effectiveness is reduced.Remember to keep the gloves DRY and Clean!It's really pricey but worth it (for a TNF product). IMHO, the only competitor would be Marmot's Windstopper gloves (which I also own) which is a bit snugger than these for relatively the same price but similar quality!
