This classic design allows for optimal protection in a variety of water temperatures. The step-in jacket can be worn alone or paired with a john for full-length protection and a double-layer of insulation around the body's core. And, the unique Gold Core interior covers 100-percent of both pieces, so divers always get the thermal and anti-microbial benefits of this high-performance neoprene. Available in a wide range of sizes, you can mix and match pieces to fit your needs. The most important benefit of Gold Core is how easy the suits are to put on. Its specially formulated interior lining provides an ultra-low-friction surface. You'll think you're putting on a pair of comfortable jeans rather than wrestling with an alligator.
