how thin do wetsuits go? ive been toying with the idea of getting one, the water here is never cold enough to need a wetsuit, but those little stingy creatures out there can get very irritating, especially after about 10 or 12 stings in a few hours.. how do they hold out to poking around in holes? ive got a few scratches on my arms when searching for lobster, would the wetsuit material live up to diving like that? ive never used one/seen anyone using one here, so i cant ask any locals for advice (the scuba guys use some short armed/legged suits, but i get jellyfish on my arms a lot so they wouldnt be much help)
