Wore this under a shell on a windy 20-degree day and never once felt a chill creep in. The intraknit panels stretch where you need them to, so swinging my arms on the climb didn't tug at the shoulders at all.

Fit is slim but not restrictive—I can layer it under a shell and still do full arm swings without bunching. The knit feels almost like a second skin, and it’s still holding up after a dozen icy trail runs with no pilling. Exactly what I wanted for those brutal single-digit mornings.

The merino is genuinely soft against skin, no itch at all, and it breathes well on climbs. Only gripe is the sleeves run a bit long on me, but it layers fine under a jacket.
