The Dragon SLS Jacket is comfortable, convenient, innovative and incredibly robust. The tank is equipped with the new SLS ballast system - Slide and Lock System. The features of this system are: a stable hold on the ballast, increased holding surfaces, active mechanical locking system, quick release mechanism, guide tunnel for easier insertion, audible feedback of correct insertion. The SLS system has a capacity of 4+4 kg on sizes XS to S, and 6+6 kg on sizes M, L and XL. There is also a stretch pocket with a neoprene panel made from the same neoprene used for wetsuits: it is abrasion resistant and has a strong horizontal zip. The fit is excellent and the performance is enhanced by the separation between the bag and straps. This permits a wider range of movement and greater stability of the bag itself, even when making adjustments during the dive. The bag is joined to the shoulder strap by a buckle that can slide on a strap, thus ensuring that there is no traction on the shoulders during inflation. The Dragon SLS Jacket allows you to change the position of the ribbon that holds the corrugate in two different positions, to satisfy both those who want maximum ease in releasing air by raising the corrugate and those who prefer a corrugate that is more restrained and close to the body.
