The Mons Royale SANTA ROSA MERINO FLEX 200 is a warm, unisex balaclava made from merino wool. The system of connecting the upper part to the lower part allows you to adjust everything so that the balaclava fits you perfectly and does not interfere anywhere under the helmet. The long and practical front panel covers the neck perfectly. For girls or long-haired mountaineers, there is a ponytail opening on the back. Merino is a soft sheep's wool that wicks the sweat away while keeping the body temperature at an optimal level without any odours.
