I have had a pair of Simms Classic Guide's, which are pretty well used up, and a pair of G3 Guide's most recently that have really held up well. I've never had any leak issues with either pair, except when I needed to take a leak. I bought a new pair of Dan Bailey Yellowstone Guide's on ebay about a month ago at a helluva good price, and they are good looking waders. I've not worn those enough to give a report on their sturdiness, although they have not leaked during the 2 or 3 times I have worn them. A couple of my regular fishing buddies have been wearing Dan Bailey Lightweight's for the past 3 years or so and have never had any issues with them. A lot of dealers are having closeouts on their waders right now, so you can probably get a bargain on a pair.
