Blue Nike running jacket, size M

I lost my blue Nike running jacket, size M, yesterday around 3pm. It's a lightweight windbreaker in electric cobalt with a white swoosh on the chest and a small reflective stripe along the back. I had it on while I was walking along Whatcom Creek Trailhead at Railroad Ave and Maple Street in downtown Bellingham, near the old train depot. There's a tiny coffee stain on the left sleeve and a red carabiner clipped to the zipper. It has sentimental value—it’s the jacket I wear for my daily runs and it was a gift from my sister. If anyone found it, I’d really appreciate getting it back; please leave it at the Lost & Found desk at the downtown library and I’ll pick it up there.
