The winter sucks since it gets super dark early, and that's when I usually try to fit a run in. I looked around for a flattering, reflective jacket that wouldn't make me look like some sort of boxy neon square and this jacket seems to fix the problem. It's definitely more of a light windbreaker fabric, more for layering in the winter. The cuffs/thumb holes are made of a super comfy fabric. Very soft.
I'm 5'5", 130ish lbs and while the sleeves and shoulders fit well, the torso was slightly wider than I wanted (I prefer fitted like the photo). But this really isn't an issue since it makes room for layers underneath.
Visibility at night is also great. Feel much safer.
