I bought this last Spring for those days when you need a little wind protection but not much insulation. I'm happy with it for that purpose. Love the fit, not loose not tight. Good for light layering. Love the high viz color. It's good to be seen. Paid about $30 for it which is a good price these days. The zipper has held up so far, so I would recommend.
I use the vest from fall through spring and sometimes in the summer on cool mornings. I live in CA so the vest is perfect for this area. The size (Large) is true to form. I am 511 175 lbs and will wear clothes underneath and it fits fine. Good zipper and large rear pocket. Very satisfied,
