I bought a Rab Valiance late last year and it's honestly the best Jacket I've ever had. It's warm as hell, windproof and waterproof (pertex). Down insulation in some parts, but parts which get wetter (hood, sleeves) are synthetic.
I can second that. I have one and it’s brilliant. You don’t need to be precious about it getting wet and the shell makes it totally windproof so increases the warmth. Love it!
