Tech Fabric Merino

A bi-component thermal fabric combining 51% merino wool and 49% polyester. Superfine 18.5 micron New Zealand merino wicks sweat away from your skin while the polyester provides a durable, non-pill outer. Lightweight at just 160gm/m2 and machine washable. Developed by Ground Effect and knitted for us in New Zealand.

▹ Man vs Wild

Merino is unrivalled for comfort as a body layer. It absorbs more moisture than synthetic fibres, mopping up excess sweat rather than letting it settle and cool on your skin. However high-aerobic activities like cycling will often overload ordinary merino. Heatwave's polyester component repels moisture to avoid total saturation of the fabric - so it dries faster to keep you toasty.

▹ Snug-as-a-Bug Fit

Heatwave™ Merino tops are intended to hug your body, ensuring the fabric sits against your skin to wick sweat away - keeping you dry and not chilling out.

▹ Hot 'n' Cold

As a single garment Heatwave™ Merino regulates your temperature through a wide range of conditions. Delivering comfort in all but the hottest climes. Yet it is versatile enough to layer under a WindFoil™, Vortex™ or HydroFoil™ shell in winter.
