The best waders are ones that are on sale and don’t leak. Look into any manufacturers warranty’s as that would make me sway toward a company. Fact is all brands suck all brands are nice. It’s sewn together material. But waders with the goop on the seams tend to be bettter (yet still leak when new). Really hit or miss. I would buy the best deal at a place close to home for quick returns. Cabelas still randomly allows wader exchanges, not a bad deal. Ultimately you can forget about your 20 year experience with one set of waders. I hunt 20 times a year not including fishing and In my garage is 6 pairs of waders. Some expensive some cheap. Most have been exchanged severs times. Point is. Don’t waste a ton of money, buy from bass pro/cabelas/Rogers on sale and they *might* back you up when you have a problem.
Buy aqua seal and use a flashlight in waders in a dark room. See light? Patch it
