I've worn this on chilly morning runs and even while lounging around the house, and it keeps me comfortable without any itchiness. The lightweight feel is perfect for layering under a jacket, and it's held up great after several washes already.

The 88% merino and 12% nylon blend feels soft against the skin without any itch, and it kept me comfortable during a chilly morning hike. It breathes well when I work up a sweat, so I can wear it all day without overheating.

I've been wearing this base layer for weekend hikes and it breathes really well even when I start sweating, then dries fast before I get cold. The wool-nylon blend feels soft against my skin without any itchiness.
