Spiro Pro Base Layer

Made in INNERGY® 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.

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.
