I have heard that the Lobster gloves of various brands are good for winter cycling. The current
gloves that I have are good down to 25, but after that my fingers arrive at work cold and red. Can anyone suggest gloves that work down to -10 or -20?

For temps that cold, I would get a pair of shell mitts to pull over my current gloves. Less than dexterous, but in temps like that, that's the least of my worries.

+1 on mittens. I use ski mitts- I never found gloves that work in cold weather.

I use Burton Snowboarding glove liners down to about 25F, which is about as cold as i care to bike in. Past that, i have some wool/thinsulate gloves that have a flip-down mitten up top and fingerless gloves if the mittens aren't down. I have a thin wool glove as a liner for those, which makes up for the fingerless part. I've never gotten cold wearing those.

My hands haven't been cold since I started using them. Down to 10°F so far, or something like that (maybe less) and I expect them to work much lower. You mount them on your handlebars, and then wear gloves under them. You need a lot less glove when the wind, rain, and snow never reach your hands.

+1 as well. I use Dakine snoboard mittens over my regular riding gloves. You have to get used to shifting with them, but your hands will be toasty warm...

I wore my MEC lobster gloves all day Monday building snow forts, tobogganing, and snowmobiling. It was -12C and my hands were toasty. You can also combine them with a pair of thin gloves for extra warmth.

I don't ride a bike when it's below freezing. Personally, I think you guys are nuts - but in a nice way.

Having spent alot of time outside in the mountains, I agree that alot of the same clothing items should work for cycling - with emphasis on preventing wind chill.
