The magic is in the premium merino blend fabric, sourced from the renowned textile region of Biella, Italy. It's incredibly soft against the skin, offers natural temperature regulation, breathability and odour-resistant properties, making it ideal for a wide range of conditions – from cool mornings to warm summer afternoons.

A relaxed fit provides ease of movement. From hard rugged climbs to leisurely explorations, the lightweight airy construction further enhances comfort as pace and terrain varies. Finished with reflective detailed for enhanced visibility in low light.

The ARC Merino T-Shirt also comes in a short sleeve for warmer weather.

Wore this on a chilly morning hike and never once felt clammy or overheated, which is wild for a long sleeve. The temperature regulation actually works, and it still looks clean enough to wear straight to lunch after.

The merino blend is noticeably softer than my other wool shirts, no itch at all even on bare skin. It kept me comfortable on a long flight where cabins usually leave me either clammy or freezing.

Wore this on a chilly morning hike and stayed comfortable the whole time, no clammy feeling even when I worked up a sweat. The merino breathes way better than the cotton tees I used to wear.
