Replying to Gloves

Ok, this season was my first skiing...was a boarder before that but that's not what I'm here to talk about. For the whole time I boarded I never really bothered with gloves outside of the Wal-Mart specials that I would get like 4 pairs of. I really have a problem with circulation in my hands, so they get cold real easily, making so I usually have to wear at least two pairs of gloves at one time.

What I want to know is, what makes the brand name gloves so special? is it grip that makes grabs easier, good flexibility, or is it how warm they keep you? I am looking to invest in a nice pair of gloves, but want a pair that will keep me warm with good grip that is not bulky at the same time. I am going to assume that I will have to wear my underarmor under gloves most of the time, but that is just something that I have always had to do.

Any suggestions on a nice pair of non bulky gloves that are warm and have a nice grip would be great.
