There's good news and bad news in the word of ski gloves. The good news is there's something for everyone and everyone sport, activity and weather condition. The bad news is technology has developed in such a way that one pair of gloves no longer covers you for winter.
You could open a small boutique glove shop with what I have in my closet. I have spring gloves, snowboarding gloves, mountaineering gloves, driving gloves, Deer Valley gloves (chic ones that match my outfits and look better than they function), powder gloves, and mittens for the brutal -0 temp days. This, of course, is overkill, but I'm the first one to admit my winter fashion sense far outweighs any summer or spring style. I horde gear the way a Beverly Hills housewife covets shoes and handbags.
Pick a spring and a winter glove if you can only have two pairs and plan to ski all season.
Cold weather gloves are designed for warmth in temperatures primarily ranging from 10 to 40 degrees. Swany uses a triplex insulating system in many of their cold weather styles like the NFX-1 Bad boy which uses a ComforMax Radiant Shield Heat reflecting membrane that reflects your radiant heat back to the hand. It's also windproof, breathable, and non-bulky.
