This soft touch base layer is to be worn next to the skin to optimise use. Anatomically designed, the Spiro provides comfort and unrestricted movement. The zip collar allows for venting or keeping warm and the long back with silicone tape keeps the base layer tucked in. The Spiro Pro base layer is the perfect blend between materials and technical design resulting in an ideal mid layering for polo.

ONA SPIRO base layer

SKU: ON060103
  • Ultra light insulating and moisture wicking base layer made in INNERGY® a performance fabric engineered for high intensity sport. INNERGY® is a polyamide (PA) 6.6 microfiber with built in FIR (far infrared ray) properties. The mineral additive found in the yarn converts the thermo energy of the human body into FIR and reflects it back to the skin tissues causing deep, gentle heating. The gentle heat emitted by the fibers invigorates the body and enhances performance: boosting muscle elasticity during exercise and improving muscle recovery after. The interior knit of the fabric is highly efficient as a thermal regulator as it reacts to body temperature. This means that when the body warms up, the structure of the fabric ‘opens’ to release excessive body heat. Moisture-wicking and quick drying properties improve thermal efficiency and ensures comfort. Integrated silver ion fibres for long lasting odor control.
