Technical and anatomically shaped balaclava: The Kama GTX DW29 is made of two functional materials. Windproof, breathable GORE-TEX INFINIUM™ WINDSTOPPER® Soft Shell protects the face area.A nose hole and laser-cut vents ensure free breathing. The mechanically durable flexible perPETual fleece provides thermoregulation and an overall good feeling of comfort and protection from the weather. This product is from our new and special line that uses an eco-friendly 100% PET bottle recycling program called "perPETual". It is a unique technology where it starts as a plastic bottle and ends up being a high quality fibre with Oeko-Tex® Standard 100 certification for use in the clothing industry. KAMA thus joins the ranks of global brands that strive for environmental sustainability. It takes about 3 pet bottles to make a hood.
