OhByTheWay:
I've never used my ski gloves, just figuring they wouldn't give me enough dexterity to shift, brake, blow snot, flip off drivers [kidding!], etc., but ... I tried them out, today, and they were just fine.
I'm using old-school Deore XT shifters
Toasty warm fingers, too!
Only disadvantage I thought of (vs. my thin Seirus gloves + a shell) is: if you need dexterity, being able to pull off a layer without freezing is a plus. Guess you could accomplish that with fairly
thin liners, under ski gloves, too....
