The gloves is normal Chrome leather gloves. I picked this up with my first Python. The python just refused to get handled and continualy bit me, even with slow movement. I started using the gloves to save my hands from the bites trying to get the Python used to me. Several weeks later, the Python calmed down, and I was able to handle it as long as I had the gloves on. Any other way, and it would bite me. I later figured that the Python is picking up it's own scent from the gloves, and calms down because of this. Each snake has it's own pair of gloves I handle them with. The king snake don't mind the bare hands, but the others got raised with the gloves, so they don't like being handled any other way.
I fully agree that the gloves wont help much in a bite situation, but from what I have learned from my Python experience, it seems to be a safer option to barehands.
If anyone have a different reason as to why the gloves seem to work on snakes, please do assist. Like I said, the only possible reason I can come up with is that it smells it-self on the gloves and know that the gloves don't hurt him/her.
