Montane Featherlite top - One of the best and most useful pieces of clothing I possess. It's been going for years too. If it's blowing a real gale, it's quite noisy, but it keeps the wind out. For cragging it's nigh on perfect - pops into a back pocket and keeps the breeze off on stances. Zip's long enough that you can put it on over a helmet.
Does me over a baselayer for most Scottish winter walk-ins. I then wear it over a thin fleece and under a softshell - helps all the layers slide over each other and improves freedom of movement. Peel off the softshell at the top, and I'm set for the walk off.
