This is one of the best gear investments i have made. i used it in 12 degree conditions with some wind, with only 1 layer on underneath, and then again yesterday in 40 degree with nothing but boxers on under. tons of vents, and pockets. it is a bit baggy. i got the L, and i am 6' 210.
these gloves are good. they are not too bulky, and was able to go the day without taking them off, as i still felt i had good dexterity. kept my hands warm in some cold conditions(12 degrees wind, and deep powder)
