Category: Base Layers

We’ve selected a high-quality merino blend fabric sourced from the renowned textile region of Biella, Italy for its specific performance qualities. Temperature regulating, it keeps you warm and protected from windchill, whether descending or stopping to refuel and keeps you cool when the intensity of your ride kicks up. It’s exceptionally soft against the skin, fast-wicking and odour-resistant – so you can hang it to air out between sessions or on multi-day rides. Blended with premium synthetic fibres, the base layer ensures the added benefit of enhanced durability and stretch retention.

Featuring an open mesh structure for further optimised breathability and flatlocked low profile seams to prevent chafing - delivering exceptional comfort over long distances. Designed for a close fit, the base layer sits snugly against the skin.

Also available in sleeveless and long sleeved options.

Samuel R. ★★★★★

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.

Ryan ★★★★★

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.

Eva ★★★★★

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.
