ARC Merino Short Sleeve Base Layer

Wore this under a flannel for a breezy coastal walk and stayed comfortable the whole time, never clammy. The merino blend from Biella really does regulate temperature well, and it's soft enough that I forget I have a base layer on.

First wore it on a chilly morning hike and honestly forgot I had it on—no itch, no clammy feeling when I started sweating. The temperature regulation is real, and it dried out fast once I stopped moving.

The fabric from Biella feels noticeably finer than other merino I’ve worn, almost silky against the skin. Wore it on a chilly morning hike and stayed comfortable without any clamminess once I started sweating.
