In reply to Dopey_172: I've got a VR that I've found great for winter climbing (with light shell over the top), winter hillwalking, ski touring, general autumn cragging top, and hillrunning in abysmal blizzardy weather.
it tends to be quite a warm garment when worn next to the skin - be careful with your layering.
A l,ot of people report fitting problems with it, and in particular sleeves that ride up when you lift your arms. Perosnally I have not had that problem but if you buy one, try it on, with a harness and lift your arms up high to see if it rides up on you.
I really rate them but it is not a piece of kit that everyone gets on with.
