Ibex also makes a "Climawool" (74% nylon, 20% merino wool, 6% spandex) soft-shell jacket that fits close and layers well. The spandex stretchiness makes it very easy to move about in. I wear mine on its own or under a light-weight rain jacket or cycling jacket. I forget what name they have for this model, tho. Been sitting here turning it inside out looking for a model label, but don't see a name on or in it anywhere.
