Just want to go on the record about this "we don't need no steenking waders" concept. I've been in rivers in SE Minnesota in August without waders...I actually forgot them...brought everything else but forgot to throw the wader bag in the car. August is the time when the locals will tell you that it's already gotten too warm and the trout aren't there...BUT...

...it was still cold enough that I realized that I was beginning to exhibit signs of hypothermia after a while. It was sort of subtle because I was concentrating on the fishing and not my state of being but I realized that i was slowing down and that I could very well have made one or more of those little errors in judgement that could have resulted in my getting seriously hurt. I got out and walked back to camp to warm up.

As long as the water temperature is lower than 98.6, it's cooling off your body. If you're only in for a short time, that's one thing but if you're on a major expedition, you could very well get hypothermic and it does creep up on you. Please be careful.

Best
