A good running jacket is indispensable for a fanatical runner who is not deterred by a little cold. The Core jacket with windproof Airbloc fabric is specifically designed for windy winter days. The inside collar with woven trim provides extra warmth and comfort around your neck. The vents on the back create the ability to release heat and thus provide the necessary ventilation at the times when you are going all out. The environmentally friendly PFAS-free DWR treatment forms a protective layer against water and dirt. The jacket stays put thanks to the stretch finish in the hem. Also, the elastic sleeve cuffs make the Core jacket extra comfortable and ensure that the sleeves fit snugly. The chest pocket has room for personal items such as keys and phone. Are you going to run in the evening? The reflective details provide extra visibility in the dark.
