Whether worn with a long-sleeved jersey for autumn or spring outings, or as an insulating layer on the coldest winter days under a jacket, the KSYRIUM THERMO VEST is a highly versatile sleeveless waistcoat for men.
Easy to take anywhere, this sleeveless jacket can be stowed away in a pocket when the weather warms up. It provides innovative thermal regulation thanks to its Polartec® Alpha® fabric with windproof and water-repellent properties, successfully combining warmth, compressibility and extreme breathability like no other insulation. This makes it perfectly suited to the needs of all cyclists when combined with a lightweight windproof fabric.
This waistcoat adds the essential zipped back pockets and reflective elements.
