Mutanda Termica Classica in Merino Donna Nero

I wore these on a freezing morning hike and stayed warm without overheating. The interlock knit feels smooth against the skin, not scratchy like I expected from wool. They fit snugly but allow full range of motion for climbing.

I’ve been wearing these under jeans for hiking in 20-degree weather and they keep me warm without feeling bulky. The merino-covered elastic waistband is a nice touch—no pinching or rolling. They fit true to size and feel soft against the skin all day.

The interlock knit is denser than any other merino base layer I’ve owned, so it blocks wind without feeling stiff. The elastic waistband sits flat and doesn’t dig in, even after a full day of hiking. I’ve already worn these three times this week in freezing weather and stayed comfortably warm.
