Why choose it

Merino wool is nature's performance fabric—it regulates body temperature, wicks moisture, and resists odour, so you stay fresh even after multiple wears. The Corespun technology wraps Merino fibres around a nylon core, enhancing durability without sacrificing softness. The slim fit and flatlock seams ensure a smooth, chafe-free experience under any outer layer.
