This versatile and high-tech long-sleeved undershirt is perfect for changing conditions. Suitable for professional and leisure use all year round, this tight-fitting design has a round neckline and fitted sleeves. The hem is also longer on the back for extra comfort. This shirt is specially designed for hunters, hikers and all other backpack carriers: there is a smooth knit on the shoulders so that the strap does not rub or press. This is a very popular shirt among hunters and motorcyclists, but is suitable for all types of hobbies on land, on water or in the air. Technology The material is made of a very supple and skin-friendly silver ionized polypropylene mesh. The loops of the knitwear store air which then adapts to the body temperature and compensates for any fluctuations in the ambient temperature. Polypropylene does not absorb moisture, but wicks it away from the skin, so it always stays dry. Silver ionization prevents the growth of bacteria, so that the garment remains odorless and fresh for longer. The treatment is carried out at the manufacturing stage in the core of the fiber, so that the garment retains its properties throughout its life cycle. All seams are sewn flat so that the product is comfortable to wear and does not press or rub on the skin. Maintenance Wash at 60°C. We recommend washing the garment in a laundry bag to prevent the mesh fabric from sticking to the zippers/etc of other clothes. If you hang the garment outside between two washes and let it air for a while, you don't need to wash it as often.
