Wow, a LOT of things to think about, thank you all for your suggestions. I will take a look at all the non-Simms waders that have been mentioned. I certainly appreciate all the advice.
I've been in the same pair of Dryfts since the fall of 2015 (~30-40 days a year) with no patches or aquaseal. The only part of the waders which are beat up are the gravel guards which have been updated to neoprene since I purchased mine.
I don't fish a ton of salt water, so I have no experience there. My fishing buddies with more expensive waders have done multiple repairs to their waders which they purchased well after I got mine.
They can get toasty on a sunny day in the warmer months but that is really the only negative comment I can make about them.
Great product at a very reasonable price. I will get a new pair from them once my current pair is no longer serviceable.
That seems to be happening with a lot of my clothing!but their stuff used to be much roomier then it is now in my opinion.
