I tried this vest in a medium (5'9, 160lb) and it was slightly too baggy/flappy in the wind, so I downsized, and this one is perfect - as long as I don't put on my usual winter weight. Zipper is great, and it surpasses my old PNS vest that had a lousy zipper, poor fit, and didn't last very long.

Exactly what I was looking for at a great price!

Fit is a tad larger thab expected. Quality material.

While the quality of this product is very good, it is sized extremely small. Size 4xl was too small for me and I am 6', 245lbs and have a 48"chest. Size chart was not even close for my fit.

Far too small. 2XL is equivalent to like a pearl izumi large
