Simms has released their newest iteration of the G4Z Waders, their premium zippered-front chest waders made in Bozeman, Montana. We’ve been fans of the G-series waders for a long time, so we were excited to check out the newest generation and compare it to the previous edition. In this review we’ll discuss the G4Z’s new features, what stayed the same, and what went away. We’ll also discuss whether or not these GORE-TEX waders are worth the hefty price, and who should consider buying them.
