The Klimatex ARVID KLIMAFEEL men's functional t-shirt is incredibly soft and pleasant to the touch, keeping you comfortable and fresh even during challenging mountain hikes. The material combines the natural softness of modal with the functionality of polypropylene and the flexibility of Lycra®. The inner polypropylene layer, in direct contact with your skin, insulates heat while efficiently wicking moisture away to the absorbent outer layer, keeping your body dry and comfortable - modal. Modal® is a natural fibre that is known primarily for its softness and pleasant feeling on the skin. The outer layer of the material facilitates quick moisture removal and gradual evaporation, effectively transporting sweat away from your skin and to the outer layers. It has a pleasant, cooling effect. The T-shirt is sewn with flat seams so that they do not irritate your sensitive skin.
