The New Aqua Lock line features: enhanced stretch, revolutionary Quik Dry interior and locking zipperless wrist and ankle closures. At the heart of the Aqua Lock series are the industry's original interlocking wetsuit wrist, ankle and neck openings. Each opening is designed specifically to mate with interlocking Aqua Lock hoods, boots and gloves using a new zipperless sealing system to form a nearly impenetrable seal that minimizes cold water entry into the Aqua Lock ensemble.
