@Cerberus ^^^^ That is one each of the various handshoes I regularly wear under this or that condition, depending. Sometimes I wear two upon a single hand. Numbering clockwise from the shiny black mitten at the northwest corner, that's likely the warmest. It's fuzzy inside. #2 is only for mild weather. I'm just guessing that #3 would suit you better for biking. #4&5 are liners. The OR one I mentioned earlier is #6. #7 is a grey Patagonia hybrid mitten. #8 is serious.
Anything that splits your fingers will be less good at keeping those fingers warm than something that does not.
Those are variously sized, but they're all either Men's Mediums or Men's Larges. You'd need a large, perhaps greater but you'd have to check.
Women's Large is like Men's Medium. Or less. Be careful of that.
@Cerberus I have winter here, and I expect to face it daily.
Some of those are too light for honest winter.
