The SENSITIVE collection is specially designed for people with sensitive skin, for whom all wool qualities are irritating to the skin. The hood has a non-itchy bamboo fiber knit on the inside. Double knit (outside 100% merino, inside 100% bamboo) guarantees heat insulation, moisture transfer and antibacterial properties of the helmet hood. Merino wool fibers bind warming air between the skin and the shell layer. The merino bamboo knit effectively moves moisture away from the skin. Thanks to the antibacterial property, simply airing is often enough to refresh the garment. The merino wool used by North Outdoor is ethically produced mulesing-free wool.
