Dryarn provides top levels of breathability. Many other fibers don't allow the body to breathe properly, blocking the body's normal perspiration process altogether or, at best, allowing it to function for a limited period only. During light sports activities Dryarn controls the flow of perspiration vapor to keep the body's thermal regulation system well balanced and the skin dry. Where higher levels of physical effort are involved, Dryarn will transfer sweat from the skin to the surface of the fiber and onwards to the outside of the fabric and into the environment. It does this quickly and efficiently. Dryarn provides excellent insulation. This is because it has the lowest thermal conductivity of any fiber thereby providing the best insulation against the outside environment. Dryarn creates a breathing barrier which insulates from the outside world and carries sweat from the inside out. An insulating, protective barrier which also breathes to ensure that the skin stays dry; warm in winter and cool in summer. In competition sport just a few grams less will save precious seconds. In free time activities, the lightness of garment will make it more pleasing and comfortable to wear. Dryarn has low specific weight. This means that garments made of Dryarn will be much, much lighter while maintaining excellent levels of thermal insulation. Much more comfortable because you won’t need so many layers of clothing to keep warm.
