In reply to Romain87s:
Everyone is different so you may need some experimentation to find what works for you. My clothing set up for most winter climbing is as follows:
* socks, one pair liner socks with a pair of thick wooly ones on top
* merino long johns
* Paramo Aspira trousers - bomb proof, not fully waterproof but I avoid winter climbing in the rain
* Short sleeved cheapo synthetic t-shirt***
* 200 weight or similar type weight long sleeved merino top.
* Fleece top, just a thin 50-100 weight one
* Arcteryx Atom LT hoody**
* Montane Extreme Jacket or a very bulky Haglofs belay jacket.
* Goretex shell on top
* Thick hat for climbing in - I have a thin merino one for the walk in
* More gloves than you can shake a stick at - I'll climb in one pair and have another pair of dry ones stuffed in my jacket with at least one or two more pairs in my pack!
I wear all my layers from the start to the end of the climb. I've never got too hot yet. I invariably look like the michelin man/woman but if I'm warm I don't care.
** Not always, depends on the temperature, if it's cold then I'll probably wear this too!
*** Just for walking in, I change into the other layers at the gearing up spot. I get hot walking in and like to start a climb with a dry base layer etc
