It's a stereotype, but my Dr. says keeping your CORE warm (fleece vests and such) is key to keeping Reynaud's controlled. It seems to be working for me ... I never have problems during exercise, but have problems immediately after a workout (especially in cold weather, but not always), the blood flow to hands and feet just shuts down...even with a proper cooldown and everything. A hat & a fuzzy vest seem to work to minimize this ... which is good. Purple popsicle fingers are understandable in January ... but in June???? That's a little much.
