I wear waterproof ski gloves that have kept my fingers warm and dry for the past 3 years. The fingers are soft and flexible with no strain with my hands curled around the grips but they are bulky. I find I have to use 3 fingers on the brake levers or when I squeeze them with 2 fingers, the bulky stuffing gets in the way of actually slowing and stopping.
The waterproofness is excellent and I was reminded of how well the gloves keep my hands warm and dry when we had a downpour last week. My gloves were soaked but my hands were bone dry.
The gloves are most comfortable when the temps are close to freezing to about -10 Celsius.
I think the gloves were $19 at a camping store in Toronto. They were a gift for Christmas several years ago and I don't recall the name of the company that made the gloves. Auden? I'd have to check the label.
