The Matterhorn is a highly functional deep-freezing coverall that protects you perfectly in extremely cold temperatures of -40°C thanks to its fixed quilted thermal lining. The inner collar is made of fleece. The waist is elasticated to make it easier to put on the overalls, and a zipper is provided at the bottom of the leg section. This is covered with a flap with Velcro fastening to prevent heat loss. Areas sensitive to abrasion, such as the shoulders, elbows and knees, have been given extra reinforcement.
