The Chrono? Expert Wind Jacket is a go-to barrier against wind and chill thanks to 2-way stretch windproof ripstop fabric that packs down into a jersey pocket with ease. The form-fitting silhouette features a DWR coating to resist damp conditions and grime, while a perforated back panel helps to optimize temperature and moisture management inside. Genuine 3M Reflective logos and highlights add visual pop to enhance visibility in low light conditions.
