Product details

After months of development and testing, the Espin vest is treated with an advanced Polygiene treatment which guarantees anti-microbial protection for the lifetime of the garment. Polygiene utilises recycled silver to tackle odour producing bacteria at source to keep you stench free. Polygiene does not interfere with the bodies natural bacteria equibirium. Allowing you to pack light and train harder.

Laser cut holes placed in strategically body mapped sweat zones provide impeccable moisture transfer and enhanced drying time, allowing you to train longer and harder. Complimented by the unique honeycomb structure of our warp knit fabric which evaporates moisture before it turns to sweat.

The tridimensional structure of our fabric allows for a slim, athletic cut providing an enhanced range of motion in all environments. The Hoddle tee has been tailored to an athletes profile, eliminating excess fabric to act as a second skin and providing the aerodynamic benefits of a streamlined cut. We have also incorporated a curved dropped hem and raglan sleeves allowing for the ultimate athletic fit.
