Build muscle without wearing lifting gloves. Neoprene Dumbbells are covered in a synthetic rubber, giving them a cushioned feel for a comfortable grip so gloves are no longer needed. They are resistant to oil and sweat so you are less likely to accidentally drop them and are sealed off from moisture so they won’t rust like their metal counterparts. Soft neoprene weights don’t damage floors or tables. These dumbbells are priced individually, stack easily and are made in a variety of attractive colors so you can quickly find the weights you need.
