The CODEZERO ELITE Suits/Tops uses biokinetic inserts with the most advanced technology for superior impact protection and minimal interference. When you're working hard on the water, your vulnerable to the continuous impact. the force of the impact generates energy that the unprotected muscles have to absorb, leading to tissue damage and overall muscular deterioration. Gul Elite Impact Protection uses an ultra-light, ultra-thin layer of high density ACF® foam which provides superior contusion protection by absorbing 90% of the shock from impact. ACF® is Gul’s high performance open-cell foam that absorbs most of the energy not only from the impact, it also minimizes the energy bounce back that a sailor experiences when sailing, allowing you to perform beyond what’s necessary.
