Replying to Warm gloves????

alright so i need a pair of gloves/mittens that will keep my digits warm everyday i'm on the slope. Now i realize that there are probably hundreds of previous threads regarding gloves but instead of looking through every single thread i though i'd just be easier to make my own. So first off what are some of the better gloves out there today. Second what type of materials are better at retaining heat . and lastly how much is a good pair of gloves/mittens going to cost me. Any info is greatly appreciated (karma+), thanks.
