Bought the hex dumbbell made with virgin rubber (pro hex virgin rubber with black handles and Vulcan logo) Absolutely a work of art (as far as dumbbells go:). I love that the handles are rubberized and clearly will not strip - that means they have been more comfortable in hand, and I don't end up with in hand rough spots from working with the dumbbells (all the benefits without tough spots developing in hand) who doesn't want that. Clearly a quality product. Just wish they were not out of the additional sizes i need during this COVID period. Team Vulcan you are missing out on invaluable revenue! Keep safe and thank you for a quality product.
