These easy to store aquatic barbells are a perfect addition to your water aerobics workout. They come as a set of 2. Made from EVA foam, they measure 12"long x 6"wide. While the EVA foam has low water absorption, we recommend storing the weights on end in a tray so any water that may have accumulated can drain. The resistance of the barbells will provide an overall workout for your upper body, lower back and abs. Warning: These are not to be used as a flotation device. Made by Trademark Innovations.
