The men's ultralight running vest Klimatex AREVIG is made of a very durable densely woven material that protects you from the wind and repels water. The back part is complemented by a very breathable mesh so you don't have to worry about an uncomfortably sweaty back. The mesh takes care of the ventilation perfectly and is also stretchy, so the vest won't restrict your movement. The lower edge and armholes are finished with an elastic band and reflective elements are effectively placed on the front and back. There are no pockets on the vest to ensure the lowest possible weight and volume after packing.
