As well as ergonomically placed Max Wick™ for increased breathability in areas where we run hot and Polygiene® anti-microbial mesh in highest vent areas.

The heat reflective properties of the Seirus® exclusive Heatwave™ material mean you can get the warmth you need in just one base layer, no more piling on so many layers just to go outside.
