It is designed for intervention teams and line units as a basic protective layer for all-day wear. It maintains the user's thermal comfort thanks to the unique structure of knitting finest merino fibers with a diameter of only 16.5 microns. 
At the same time, this latest technology provides an extremely fast drying after any physical exertion.

Special anti-bacterial properties Merino fibers do not burden your organism with foreign substances such as silver ions or chemical fiber treatment.
