Mine is generic sweater and sweat pants with thin rain jacket and pants over top. Pogies are godsend and enable super basic gloves to be enough. I tried insulated and heated gloves but the extra insulation increases fatigue when braking and shifting and wind chill negates the heating at even low to moderate speeds. Shows I have tried a bunch of wacky stuff like silicone socks that go over the shoes and up the leg a bit, heated insoles, etc but just a proper winter cycling boot ended up being the most comfortable and effective. Helmet I just have two. One with vents and one without and I wear them with a thin toque if it’s cold enough, and the hood of the raincoat is thin enough to go under the helmet.
