I've got so many gloves, it's not even funny.
No, really-- it's not funny, the pairs are EVERYWHERE. :joke:
For winter (I commute year-round, rain or snow), my current reliables:
1. Dainese Scout-Evo Gore-Tex gloves. The ones I use the most: very warm, armored, and TOTALLY waterproof. Only downside is that the gauntlet is too narrow to fit over most jackets, so I wear the gauntlet inside the jacket. Fine on my Spyder with a big windshield-- I don't get a lot of air hitting my hands at the grip-- but if you do have a lot of airflow, the wind may get up into your jacket.

2. Fly Terra-Trek gloves. A cheaper alternative, these are also warm, and somewhat waterproof. A softer glove, some padding but no real armor, it's a lot easier to throw on than my Dainese.

3. Klim Caribou Mittens. Not armored at all, but very warm and waterproof, and the easiest to throw on in a hurry.

4. Gerbing T5 heated gloves. Exceptionally warm when on; moderately warm when off (but strangely breezy, weird). Not armored, but leather is thick and padded in all the right places. I've never had any issues with the wiring being uncomfortable. If you've adapted your Spyder with a dashboard socket, heated gear is the best option for winter riding.

That all said, I ride with the heated gear down into the 30s all day, but cooler than that, the wind will overpower even the heated gear. This year, I'm seriously considering finally buying a pair of Hippo Hands-- again, blocking the wind is the single most valuable thing you can do to keep your hands warm, and that's what the Hippo Hands will give you. :thumbup:
