Warm functional sweatshirt of high weight made from quality merino wool and polyamide silk. It is said that it is windiest at the top. That's exactly why we developed Merino Extreme UP. The double-layer knit is the perfect partner for every top performance. The high Merino content perfectly warms you up to operating temperature and then ensures precise moisture wicking. Wool with added lanolin also excels in antibacterial properties and a self-cleaning effect. You can sweat through your clothes completely, and even a top-trained police dog wouldn't be able to sniff you out by the smell. The added polyamide silk then ensures high elasticity and strength.
