Women's lightweight merino zippered sweatshirt is a great functional piece for all conditions. You can use it for year-round wear in the city and in nature. 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. 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.
