Even the $600 Simms G4 get holes in them... It really does depend on what kind of fishing you're doing.. Humping through the bush to your fav steelhead spot will end up with pin holes/tears in your waders regardless of how much you spent on them. I run two pairs... Simms G3 and a set of cheaper Simms Riverteks. When one set has a hole/leak I use the back up set..
If you're walking from the Erindale Parking lot down to the Credit, you can pretty much get away with anything
