Functional shirt Omaha in black. Material: 57% polypropylene, 34% polyamide, 9% elastane. The shirt is odor-resistant, moisture-regulating, and antimicrobial. Polypropylene is a durable and lightweight synthetic fiber that is particularly well-suited for sweat-inducing activities. It retains body heat similarly to wool, but is more elastic and lighter. Since the fiber hardly absorbs moisture, the material remains almost dry as it effectively wicks away moisture. Functional underwear made from these yarns is very resilient and long-lasting. The blend with polyamide ensures optimal drying properties. The use of elastane makes the underwear highly elastic and provides a perfect fit. The antimicrobial treatment prevents the growth of bacteria on the surface and the formation of odors.
