I`m not going into any research at all..the gaiters were tested with a Death Adder biting them.
I have nothing to do with them other than allowing the use of my photo`s.
And as far as thick cotton tell that to the multitude that have been bitten through thick jeans.
Note that most pro snake handlers "in the ring" at fairs/shows usually wear 'something substantial' under their trousers while doing the shows..i was told by one of the fellas and dont blame him when walking around all sorts slithering here and there through his legs.
