If you get cold just push the ttr up a hill for 10-20 yards, instant heat / heart failure. I'd recommend the jkt I have but doesn't look like they make/sell em anymore.

Wind/Water proof, breathable, light weight, loose fitting to get armor extra layers in, tight fitting cuffs / high collar to stop draughts and cheap. Only one choice.

Army gore-tex loads of stuff out there.

Preaching to the choir here but it's good advice for anyone else looking.

Keep your hands and feet warm, you can have the worlds warmest coat but if your feet/hands are cold the body pumps the warm blood from the body core to the cold bits.

For the tootsies Gortex boot liners really only use these in the cold or if doing a "wet one".

Gloves for me the best are neoprene, really thin (I don't like thick gloves offroad), and work like a wetsuit, bit cold if they're wet when you put em back on but soon warm up.

Stop the draughts getting in any cold air getting in via the cuffs or collar will soon displace the warm air generated by body heat.

Layers, I use the same gear winter/summer with just different layers underneath. Use the man made stuff lighter and dries out quick.

Food, take a flask for a hot drink or stop at cafe etc and get summit hot.

HTH.
