I am not a Simms fan. We have two of the jackets, and since we live on and fish saltwater I would not expect their zippers to be made of inferior metals which corrode in the presense of saltwater. They did replace them (the zippers) with more metal ones. Plastic would have worked very nicely....which I suggested when I sent them in. They did do the job promptly.

Chota makes much better quality, at less cost too.
