I too suffer from Raynaulds and have tried many options.
This year I’m trying the Gerbing Gyde Featherweight Heated gloves. They are very lightweight and dexterous. Easy to shift with. I just got them and have only done one ride using them, but my hands were sweating. I think the battery placement may be too low and I’ll end up pushing the batteries up my sleeves. But as far as warmth, they seem to work well.
