The Kilpi FLOW-M is a men's ultra lightweight vest suitable for cycling, running or outdoor activities. The SIBERIUM DWR WB material serves as protection against the wind and the cold. The mesh material on the back improves micro-ventilation. The weight of the vest in a size M is only 90g and is easily folded into the side pocket. Distinctive reflective elements on the front and back improve visibility in the dark and twilight. There are two handy access openings on the back into the pockets on the jersey. The Kilpi FLOW-M is available in several colours.
