I’m grateful for this jacket as it works on so many levels. I use it for running, early morning walks, and errands. I might grab a backup.
My son loves it. Great for spring track.
Perfect fit for running. Trim but not tight. Disappears when not needed. Super soft next to the skin. Love the back vents.
So many pockets! This is an awesome top and surprisingly breathable. Highly recommend!
