Gloves:
Last winter I was using a pair of Swix "lobster claw" ski mittens on my winter commute. They were okay, not extremely warm but warm enough for my relatively short commute, and flexible enough not to hinder gear changing.
I've been wearing them in the cold/wet Autumn this year (-2C to +5) and they aren't waterproof (or at least they aren't any more) and I can feel the wind through them these days so I decided to look around for some new ones.
Seems like there is a lot of choice of gloves but not a lot of
good choice out there for bike specific winter gloves that can really deal with sub zero temperatures.
I finally came across the 45 North gloves (I should have know as I have their winter tires and they are just awesome).

I decided on the Sturmfist 4 which are a halfway house between glove and lobster mitten and are rated to -18C.
Strangely, the price I found them for in Norway was lower than what I could find elsewhere and I got free shipping - $120 is a pretty good price considering what you get for your money; a heavy duty, waterproof glove, with goat leather palm and merino wool lining plus removable merino wool liners. The removable liners have a silicon strip pattern on the palm so they can be used separately on less cold, dry days.
First impressions - just one ride this morning - warm without the liners. It was only +5C this morning so not very cold. Wind proof without a doubt. The feel bulky compared to my old winter gloves and a little stiff but I hope they will become more supple over the next few weeks. Size seems to be spot on for the outer glove (I usually use a large glove, large here is a size 9) and is a comfortable fit. With the liner, they feel a little tight but not unwearable. I hope they will loosen up a little after a few more days. If certainly recommend going up to the XL if you're borderline though.
All in all, so far, I'm pleased with them and they look like they will keep me toasty in most of the weather Norway can throw at me and I'll not be on a bike for anything they can't.
