I have a pair of those Wal-mart hodgeman's.
I'll tell you, I cannot complain. They were absolutely a life saver in late October goin down Pine Creek Gorge a few days after heavy rain. I was able to comfortably wear them all day while sitting in a canoe and they came in handy. I had to jump out of the canoe several times to dodge some pretty wicked looking rapids with water in the 40's.
If they're $15 at my Wal-mart... I might have to pick up a pair for my little bro.
