Underpar, I dont' know because I've never used them, but I have never used them for that reason, they look like they'd be clumsy. My GF uses some non powdered vinyl gloves when she's gotta work in the tank, I use my good ol' bare hands. But I'm not as sensitive to the stings of my corals as she is...and some people can be very sensitive at that, take caution. Just because they don't bother me know, doesn't mean I won't find one eventually that puts me in the hospital with a baseball glove sized hand.
