The Comfort Wool Men's Long Sleeve T-Shirt is the highest quality everyday underwear for active and exceptional customers. The outer layer is made of soft, very thin, and delicate 100% Merino sheep wool. Thanks to the high elasticity of the wool, the underwear does not wrinkle and does not constrict. It fits the body perfectly and allows for plenty of freedom in choosing the next layers of clothing. The combination of natural fibers with polyamide and the use of a two-layer, seamless construction provide exceptional thermoregulating properties while ensuring maximum comfort. The underwear effectively helps to maintain a constant body temperature and protects the body from cooling down and overheating. The product has been dermatologically tested – it does not irritate and does not cause allergies. Composition: 57% polyamide, 41% wool, 2% elastane. Weight: 160 g/m².
