Mizuno Breath Thermo Running Jacket for Women - Lightweight, Insulated & Windproof - Perfect for Cold Weather Jogging, Hiking & Outdoor Workouts

I was extremely surprised when I tried on my jacket to find it was much larger than expected. I typically wear an XS but ordered a size up just in case. Even with a mid layer and base layer, it is still quite large. Despite the oversize, it served me well on my run in the lower temperature.Lite weight and love running in it.
