Not a simple question it seems.
Problem is this. Suppose I do a decent climb where the top is around freezing. It seems that if I put down enough power, I’ll heat up enough that a short finger glove will work. The problem is downhill. My fingers freeze and can barely move anymore (could also be a padding issue, and me doing the death grip for the rim brakes). On the Haute Route Dolomites I solved this problem by using full on winter gloves (think about skiing gloves), which of course has the downside taking up an insane amount in your jersey pockets.
So what I am looking for is a pair of gloves, that keep my fingers warm enough around freezing, avoid numbness as much as possible, but do not need to be water proof (which is where full on winter gloves go over board). And of course the smallest space requirement in the jersey pockets.
The glove that comes closet to what I am looking for were the LeCol “Pro Lightweight Glove” … But they are not warm enough …
