Men's Klimatex vest with a back part supplemented with highly breathable mesh Men's ultralight running vest Klimatex AREVIG (code AREVIG 540) consists of a very durable densely woven material that protects you against wind and repels water. The back part is supplemented with a very breathable mesh, so you don't have to worry about an unpleasantly sweaty back. The mesh takes care of the ventilation perfectly and is also flexible, so the vest will not restrict your movement. The bottom edge and the armholes are finished with flexible elastic and reflective elements are effectively distributed on the front and back. For the lowest possible weight and volume after packing, there are no pockets on the vest. A combination of functional materials. The woven material protects against wind and repels water. 1: Mesh: 86% Polyester, 14% Elastane
