Thought I'd post a link to what has become one of the most versatile bits of my outdoor wardrobe. Might be of some interest to folks for winter use.
I was recommended mine by a mountaineer who swore by them.
Thick pile lining with a pertex shell, really warm, excellent wicking, light and fast drying.
Mines been used for everything from highish altitude mountain walking to camping and general loafing around. It's 3 years old and still going strong.
Can be used next to skin although I use mine over a helly so it doesn't need washing as often. They would be excellent for highseat use andf I find mine great under a DPM jacket when laid up sniping rabbits.
