The gloves I wear most through the winter are my Defeet dura gloves, not bulky so easy to carry a spare pair and you can double up on colder days. But I understand these won’t be enough for some people. There are only one or two rides a year when I need to go full sealskinz. My one item I wear every ride is a Ground Effect baked Alaska, it can be used on its own, as an outer layer or as a mid layer. If I’m not wearing one I’ll always have a gilet with me for the next 6 months, my preferred one just now is an Altura job with a light fleece on the inside of the front but a very breathable back, packs really small but is a bit more than just a windproof.
