Wore this under a flannel on a cold hike and never once felt clammy, which is rare for me with wool base layers. The updated fit sits close without bunching at the shoulders, and the 100% merino somehow doesn't itch at all.
The merino is genuinely soft against my skin, no itch at all, which surprised me since wool usually bothers me. I wore it skiing all day and it never got clammy, and the updated fit sits close without bunching.
