I couldn't manipulate anything to get the flat fixed with cycling gloves on. And when I took them off my finger got too cold for it in a minute. I was dressed fine for cycling. But when I stopped, all sweaty, and had to walk about a mile (in cycling shoes no less)...I was freezing!!! Since then...I try to make sure my rides on really cold days remain somewhat close to civilization.
