How long a wader lasts depends on how well it was made and how badly you abuse it. Duck guides will often run through a single pair (or at least have a failure that will need repair) in one season because they hunt so much. If you only hunt a handful of times each season, you can get years out of a wader. There’s no national average on how long waders will last, that’s why it’s important to check the warranty before buying. Because any wader, no matter the price, can leak out the box.
