Made a similar thread a couple of months ago and the general consensus seemed to be that those windowcleaners Glacier Gloves were the ones to go for. I bought some a while ago but have only just had my first actual cold(ish) weather ride in them and to sum them up in a few words would be utter utter gash. As in they're worse than the aldi gloves, which aren't even very good. And it's not even really that cold yet! First signs of numbness 5 minutes into a road ride and by 10 minutes my fingers were throbbing from the cold!
I have a feeling a lot of it is down to me having poor circulation as my hands/toes go numb very easily when it gets a bit cold. Questionable internet diagnosis seems like it might be raynaud's as my fingers and toes go white/purple very easily. Not sure what can be done about that tbh.
So who makes a good set of winter gloves that will work for those of us with poor circulation? I think I might try those mitten style ones rather than individual fingers - I'll only need them for road anyway so finger dexterity isn't that important.
