I have a pair of Hodgman's neoprene stocking foots and a pair of their regular lightweight, stocking foots. The "Neo's" are for cold water streams and winter steelheading and I also use them on cold days for digging clams down on the beach.
The clam digging, I think, actually puts the waders to a better test than their stream use, due to being subjected to salt water, sand, sharp shell fragments and sharp rocks.
Of course, after every use, I rinse them very well with fresh water and my current pair,(they're 3mm), are over 4 years old and still going strong! I've had to patch them a few times, but that's another nice thing with the Hodgman's...............they patch easily and the patches seem to hold.
However, I haven't been too impressed with my lightweights!?! It's probably just ME, but I don't care for the way they "fit" and they're not as "breathable" to me, as claimed.
I finally turned in my pop cans and bought a pair of Ghillie's, and a pair of Fishpond's bearthables. Both, of these waders are extrememly tough to abrasions and tears, have several really nice features other brands don't and are far, far, superior to anything I've owned for comfort, fit and true beathablity.
As for the "cheap and disposable factor". I fish often enough that I don't want the "disposable factor" to happen suddenly, when I'm mid-stream, or 300 miles away, and on the first day of a trip!
