The Fjällräven Singi Heater is a unisex winter hat designed for very cold and windy conditions, made from durable G-1000® HeavyDuty fabric that resists both wind and rain. A soft synthetic fur lining provides warmth, while the brim and adjustable ear flaps protect the face, cheeks, and chin from snow and cold. Additional fold-down ear panels with hearing openings provide extra protection without blocking surrounding sounds.
