The exact name of what I'm now using is: NeoSport Wetsuits Premium Neoprene 1.5mm 3/4 Finger Glove,Black,Medium
Excellent paddling gloves, and not terribly expensive. The palms seem to be leather (especially that tender place inside the thumbs). The back of the gloves is a stretchy material that dries quickly. They fasten with velco tabs on the top of the wrists.
I got a new paddle that had a design on the grips, and got awful blisters both times I used it. Once I got these gloves, I've had no more problem. Hooray!
