I remember that. i think cathe stopped selling them, because there was a problem with the weights fastening in the glove. the closure/zipper was coming open or maybe it just felt too bulky for the user. i think I remember reading about both problems. i never owned weighted gloves myself, but I was seriously considering buying some at the time.
so I would just be wary when you read the reviews for the gloves, make sure that's not an issue.
