The Winter Run Jacket from Dæhlie is a women's running jacket, perfect for cold days. The jacket feels almost weightless, even with insulating padding in the front with Primaloft Aerogel; one of the world's lightest insulation that provides low weight, while providing optimal insulation and ventilation in the right places. The jacket has a two-way zipper in the front so you can run with the jacket partially open, either from the bottom or from the top. The sleeves are shaped for the best possible fit, finished with elastic cuffs. It has many reflective details both in the front and back that provide good visibility in the dark.
