An extremely comfortable hat for training and other outdoor activities in spring, autumn, and winter. Merino wool is nature`s own insulation material - here in a mix with reinforcing polyester, which also provides good stretch. The soft, natural fibers, along with the optimal temperature regulation, give the hat high comfort. You stay warm when it`s cold and cool when it`s warm. The mulesing-free merino wool is self-cleaning and does not absorb sweat odor. And it can absorb a large amount of liquid without feeling wet. The merino wool mix is a Danish produced fabric.
