These Vinyl Coated Lace Thru Weights incorporate all the benefits of a traditional weight system. First and foremost, they increase your stability in the water, and unlike soft weights, they are lighter out-of-the-water, which also makes them easier to handle. Secondly, thanks to the curved inner surface and rounded edges, the weights are very comfortable to wear. These weights are also very durable. Manufactured with Antimony, they boast incredible hardness and resistance to deformation. Vinyl coating is chemically bonded to the weight so they won't peel and the color won’t fade. All in all, Sea Pearls Vinyl Coated Lace Thru Weights are a long favorite of many experienced divers.
