The Chrono Expert Wind Vest is a go-to barrier against wind and chill, and an ideal mid layer that pairs perfectly with a jacket when rain or colder temperatures demand it. The 2-way stretch windproof ripstop fabric packs down into a built-in pack sack, fitting into a jersey pocket with ease, and the form-fitting silhouette features a DWR coating to resist damp conditions and grime. A perforated back panel helps to optimize temperature and moisture management, while genuine 3M reflective logos and highlights add visual pop in low light conditions.
