Men’s functional underwear: The Sensor MERINO BOLD is made of extra fine Australian merino wool with a thickness of 16.5 microns that guarantees a very comfortable wearing experience that is similar to cotton clothing. The yarn dyeing, knitting and sewing are done in the Czech Republic, so the manufacturer has 100% control over the final product. Thanks to its 220 g/m2 weight and higher elasticity, the Merino Bold knit can be used as a first or second layer. Natural and permanent antibacterial, thermoregulating and insulating properties are a matter of course. The ethical, ecological and sustainable production of Merino Bold is proven by certificates such as WOOLMARK, RWS (Responsible Wool Standard), OEKOTEX.
