My vote goes to Marmot. These are the only gloves I'll ever use. Solid and experienced outerwear company that knows thier shit and can keep your hands warm and dry. Go for the gloves they make that have removable liners, its so nice to just have one pair of gloves that you wont ever get too warm or cold in.
They also are making gloves this year that have some kind of special thumb and index fingertip that allows you to more easily use the scoll thing on your iPod, but I dont know if they work at all. I tried some on today, and while I didnt have an iPod, they were really really comfy, and have a fabric on the outside that allows you to slip other gloves on over them no problem. My friend (who will also swear by thier gear) and I have a unnofficial slogan for Marmot;
You gotta go for that Marmot.
