I've recently got into fly fishing, using a donut tube to troll around in. So far I've gone out twice using my river neoprenes (Protac "River Rat" from Army & Navy) and noticed that after each outing my calves are covered in a red BURNING rash (I've been wearing shorts under my neos when it's hot out like this, for the river I've always worn jeans under them). Now I'm assuming this is due to some kind of allergy to the neoprene material, which I wasn't aware of because I've always worn pants under them. The weird thing is, that I've had these things in contact with my chest, arms etc momentarily and they never broke out with a rash. Initially I thought it might just be from the material chafing against my skin cause they do tend to get quite sweaty inside at times, but I don't think that's the case cause I'm a pretty skinny guy and barely fill up up the neos at all (they're size "L")... they're more loose on me then anything. I could barely take a shower yesterday cause even lukewarm water stings like hell, imagine 100 hornets stinging your legs!
Have any of you guys experienced this?
