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 ensures extremely fast drying of the t-shirt after any physical exertion.
