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 when you’re chilly and cool as your ride intensity and body temperature kicks up. It’s fast-drying, sweat-wicking and odour-resistant, and can hang dry between sessions or on multi-day rides without the need for washing after every use. Blended with premium synthetic fibres for 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 body, enhancing the effectiveness of its thermal regulating and moisture-wicking properties while ensuring freedom of movement.

Also available in sleeveless and short sleeved options.

James N. ★★★★★

Wore this on a chilly morning hike and it kept me comfortable the whole time without getting clammy underneath. The merino blend does exactly what it claims for temperature regulation.

George N. ★★★★★

The fabric is noticeably finer and softer than other merino layers I've owned, and that Biella weave has held its shape through multiple wears without washing. It’s been great at regulating my temperature on chilly morning runs and then sitting in a cold office afterward.

Sofia ★★★★★

Took this on a damp 40-degree hike yesterday and the fabric kept me perfectly dry under my shell—the temperature regulation is no joke. The merino blend feels noticeably smoother against the skin than my old synthetic layers, and it’s still my first choice once the sun goes down.
