The #1 tip to prolonging the life of a wader is drying your waders. It is important to dry your waders out after each use. We recommend drying the inside first (if damp) and then the outside. When drying the outside you can pull your gravel guards up until the feet are dry and then flip them down to dry the rest of the wader
Washing - Use a front load machine or hand wash. Use cold water and normal detergent that does not contain bleach. Once you have washed the waders make sure you dry them properly start by drying the inside first. Never put your waders in the dryer, the heat will adversely affect the seam tape on your waders and will void your warranty.
Fit - We offer more sizes than anyone, a good fit goes a long way to extending the life of your wader. Make it clear that people should use their exact measurements as we have already provided extra room for layering and movement.
General Care - Do not store inside your car for long periods of time excess heat will damage your waders.
Use A Mat - Always put your waders on using a protective mat to shield the neoprene feet from rocks.
Proper Layering - Do not wear jeans under your waders. Jeans are highly abrasive wearing on your waders from the inside out. More importantly jeans and sweatpants do not transfer moisture away from the body. Use proper layering (to view our layering collection, go here). Using layers such as these will help wick moisture away from your body and assist in the waders ability to breathe.
Stains - most stain removers will work fine on our waders. As long as the stain remover does not contain bleach you should be o.k.

Wet and Cold, 11/6/2015
Had my G3s for about 10 years without a leak. Too bad I gave them to my buddy.
Bought the G4s this summer and they're leaking within a month of first use, and not just in one place. I can't recall any harm/trauma/roughness that would have caused this, I've barely used them.
Repairs and warranties are great but with a 3/4-week ship and repair time, I'm going without them for November, which actually means I'm SOL for fishing for November. Guess I should have tested them before the 30-day period but It was too hot this summer/fall to even need them. Now when I do need them, they don't work.

I went fishing today and it was the most comfortable waders I ever wore. I am so glad I bought these. I can't wait to go again.

...These are the ones you want! Going on three years in my G4 Pros, they have kept me comfortable and dry all season lomng guiding in Maine, and beyond, Great Lakes, Alaskan, etc... Simply Bombproof!

I recently purchased a pair of these, and I am more than satisfied. These waders are a godsend! After going through several pairs of cheap waders, I decided to save up and get these. They are worth every penny! They are extremely comfortable, and warm in the cold water, yet cool and breathable in the sun. They block the wind 100%! They fit great, and seem very durable given how light they are. The pockets keep my stuff completely dry and the gravel guards work better against the sand than any I have used on other waders. As a surf fisherman the breathability of these waders is priceless. Walking miles through sand and in the sun, its very easy to overheat, but not in these. They keep me very very comfortable in any weather.

Ive gone through a couple of waders before decided to go over for a more high end pair of waders and then the G4 Pro was the obvious choice.
At the first try they really felt solid and you could see and feel the quality of every stitch and seem.
They really make you feel comfortable by the water and keeps you warm and dry by the river.
The only downside with this model is the size-chart that leaves no room for a perfect fit at least for my body.
A typical medium guy with a 31-32 inseam has to go around with too long legs and have a higher risk of leakage since the only choices for me is to go up or down 1 size since Medium/Short is to short and Regular Medium is to long.
Think the span of 4 inches between Medium and Medium/Short is to much, would love to see an option for people between sizes since I would love to see a Medium sized wader with Inseam 31-32

I have not yet begun to fish! At least that's what I feel these waders are telling me. I picked these bad boys up late 2012, have over a hundred days on the water with them, and they have yet to have a problem.
No leaks, no noticeable signs of wear. I am still totally dry!
Not only are these great for fly fishing SW Colorado; I would also feel confident in taking these waders into battle in a bog or swamp against a pack of baby T-rexes.
Take care of your waders, they will take care of you! You never know when you will be in the middle of a swamp, carnivores on your tail, warmth and comfort something that isn't even a problem thanks to the G4 Pros.

These waders are tough! I'm in them every chance I get and the only damage has been in the gravel guards from a stick getting stuck and the rear belt loop started to Frey but I just nicked that with a lighter and it melted and stopped the frey! My only gripe is now they put those nifty shoulder straps on! Wish they would of done that from the beginning!

Wow! Great set of waders have spent some serious time in these now and I have nothing but good to say. Very comfortable, you feel bulletproof ripping through the river in these things. Will buy another set in a second.

Love Simms but...., 5/12/2014
I'm a big fan of all Simms gear. I have plenty and the coats and technical clothing rock... however.... I have been through 3 different waders in a year. I have the same problem with the g4, the g3, and the classic guides.... they all leak. I have sent all 3 back and they still leak. granted I am in waders 200+ days a year but still.... these things should be bomb proof for the price and they aren't. everywhere there is a seem I end up with random significant wet spots on my lower legs time in and time out. It's very frustrating. I love the features and they seem to be built well but the fact is they leak.

I had over 700 days on my last pair of G4 waders, and I would bet my new pair will get just as many. Being a full time guide in the Great Smoky Mountains you punish gear and need waders that can withstand not only the elements, but you as well. My G4 waders do that with ease. I put my waders on at 6am everyday and many days wear them 14 hours or more. All day comfort, unrestricted movement, perfect fit, and most of all, superior durability. Simms waders are the best on the planet!
