The Acrux Difference – Superfine Merino First Layers

Acrux First Layer Merino outperforms regular merino designs where it matters most. Engineered for superior durability and an anti-pill finish, our merino stays softer and looks newer, longer—all while being conveniently machine washable. The seamless second-skin construction eliminates rub points for superior comfort and provides a flawless fit that actively resists losing its shape. It’s not just merino; it’s merino perfected for lasting performance.

Merino wool is the ultimate performance fabric for first layers. It naturally regulates temperature by being highly breathable and moisture-wicking, helping keep you dry and comfortable as conditions change. Its innate odour resistance also means you stay fresher, longer, with less washing.
