    Exceeds Expectations
    Ryan (PA) | February 9th, 2024
    Waited to purchase these for a good price and couldn't be more pleased with the decision. I'm 6'1", 240 lbs and opted for the XL. They are a little roomy which is good, booties fit perfect for some wool socks but could have benefited from an inseam 2" shorter. All in all, very well made and the perfect compliment to my Simms G3's and G3's wading pants. I'll save the G4Z's for cooler waters and when having to dress in layers for more warmth.

    Loyal Simms customer for years, still nursing along two older pairs of G4's from 4-7 years ago. Got a good deal on the latest G4Z from the good folks here. Using the size calculator on the Simms website, I was in between sizes, so opted for the larger pair. I found them roomy and so opted to exchange for the smaller pair. I ended up waiting about 5 months for Simms to ship the new pair. Attempts to contact Simms customer service was often futile, with either no one answering the phone, or no one able to give me an expected ship date. Finally the waders arrived and the first time on the water, I noticed the booties seemed uncomfortably snug which resulted in colder than normal feet in 50 degree water. Keep in mind, the size adjustment should not have affected the foot size. Furthermore, the waders seemed excessively long, such that the straps were adjusted to their tightest and were still loose. When I took the waders off, my lower legs were damp around the bootie seam. The staff at Reelflyrod, who always answer the phone, and are always eager to help, were quick to make things right. Unfortunately Simms informed them that they no longer had any stock to replace my waders since the new line would be released in 2024. Simms has new owners and let's hope they get their act together. I want to support American manufacturing, but I'll be wearing a competitor's wader for the next round because I already waited half a season for a defective product and don't feel like waiting another 5 months for a replacement. Kudos to Reelflyrod for their outstanding customer service. The stars are for them, not for Simms.

    Simms G4z
    Alan (CA) | August 31st, 2023
    I just replaced my old set of g4z’s that were over 10 years old and still functional without leak other than compression seepage on neoprene foot. Tried these more waders out in YNP area this year for one week and they functioned perfectly. These new waders are lighter and are more breathable than the original pairs due to the improvement in materials. The zipper is also slightly longer or better placed than the original pair. They say it’s also suppose to be just as durable but Time will tell… I would recommend this wader as it’s refined and meets all the fine requirements of a great set of waders

    Fits like a glove
    Donald E Goodwin (Maine) | May 4th, 2023
    Having been in the camp of buy cheap waders...this is my first foray into buying a 'high end' set. Always thought 'waste of money'. Couldn't have been more wrong. These things are worth every penny. The SIMMS AI bot told me my size...a leap of faith on my part. Was absolutely spot on. I usually go for the x-large...they suggested large King. Spot on fit. Quality is there...they are quite well built. Time will tell of course. But so far, so good. Love the straps, much more comfortable than the cheapos. Overall, very comfortable saying worth every penny. Expensive, for sure. But if I can get 4-5 years out of them, worth it.

    Awesome wader
    Joe Marchiano (Bath PA) | January 24th, 2023
    I’ve owned Simms g3 waders for years. I got tired of the hassle of stripping down to take a leak. The zipper is a total game changer. We’ll worth it!

    Excellent & Customizable!

    These are the best like other reviews have stated. You are paying top dollar but you are also getting one of the best warranties in the industry. I never used Simms b/c their sizing never worked for me (too large of foot booties on a Medium Wader 9-11 when I'm a size 8.5) UNTIL I found out Simms allows you to customize any wader for a small price. Check it out! I bought these G4Zs and sent them to Simms and for $50 they put a totally different foot / bootie on. I wish I had known this a decade ago and hopefully someone finds this helpful.
