Base Layers

Packing for an active weekend can provoke many a clothing conundrum; we aim to make clothing that does away with those ‘what shall I wear?’ moments altogether.
Base layers are designed to be worn next to the skin and perform day-in, day-out, no matter what you’re doing. We use anti-microbial, fast drying, and moisture wicking fabrics to be breathable summer and warm in winter. Our technical Koulin range is treated with Polygiene ™ odour control for pong-free activity; whereas the Kepler range uses pure ultrafine merino: nature’s technical fibre. Merino vs. Synthetic : Designer Ronnie shares her insight.
