Even the largest ice creams will be reliably warmed by our children's thermal set from the Merino thermal underwear line. Merino is a natural thermal material made from sheep's wool. It is also suitable for allergy sufferers and has a lot of great properties: It maintains body temperature. It warms up in winter, cools slightly in summer. It is perfectly breathable. It perfectly wicks moisture away from the body, while thanks to the structure of the fiber, it does not change the insulating properties, so even when wet, it does not get cold. The natural antibacterial property eliminates odors. Main advantages: Flat seams Anatomically shaped cut Raglan sleeve cut Underarm inserts for maximum comfort Please note that Merino is a natural material whose completely natural phenomenon is pilling, which therefore cannot be a reason for a later complaint about the product.
