I have yet to find a solutions to my cold fingers when the temp is just above freezing with rain. My hands are extra large and any rubberized gloves in that size will not allow a descent liner to be added, resulting in very cold fingers. At temps below freezing with no rain there is no problem. I'm about ready to just try covering my normal gloves with a plastic bag when it's raining ! Any ideas?

When we still lived in Michigan years ago, used to wear snowmobile mittens . . . worked great!

I carry light waterproof shell mittens which go over my gloves no matter what kind of glove it is... cycling gloves in the summer and wool gloves in the winter.

When it's cold enough for snow, I have no problem, it's only with rain and temps just above freezing when it's an issue for me.

Have you tried neoprene gloves?
You can often find reasonably priced ones meant for kayaking, and they are designed to insulate after getting wet.

Benefit is they also usually have rubberized fingers/palms to promote a good grip. MEC in Canada is where here i buy mine. REI should have something similar.

Now, I like this idea, thanks.

Paddling gloves are best for this..

Thanks, that's exactly what I was referring to. If the OP is searching online, you'll likely have more success with "paddling" glove as I think that's the more common term.

Cheers.

I like my neoprene Bar Mitts over regular cycling gloves.

Operating my brifters was a problem when I tried wearing thicker gloves particularly non-cycling gloves. Also adjusting zippers, other things requiring manual dexterity.

The Bar Mitts worked well for commuting. I would use them for the morning ride; then stash them in my panniers for the evening return when temps were warmer. Insulated gloves were too warm for the afternoon ride and took up more space in the panniers.
