The Rock diving jacket is super durable and guarantees an excellent fit. The Rock's Bag is made from strong 420 denier Cordura nylon, with Tyrpol reinforcements on the shoulder straps and pockets to ensure high wear resistance. The connection of the bag to the harness allows the bag to expand outwards, avoiding the annoying phenomena of chest compression that can occur during a dive. The back of the skirt is very stable and padded, with Tyrpol protection for better comfort. The skirt is equipped with no less than 6 stainless steel D-rings, folded and strategically placed for easy and safe use. The quick release buckles are made of high-strength technopolymer. The ventral buckle is 50 mm, the buckles on the shoulder straps are 40 mm. The skirt is also equipped with a 20 mm star buckle in which a special whistle is integrated to further improve safety. Inside the right pocket there is an elastic fastening ring. The pockets also have special openings for the octopus and pressure gauge or console. The jacket is equipped with two quick release and relief valves, one on the right shoulder and one on the lower right, in addition to the corrugated drain valve. All valves are "low profile" for minimal mass and resistance. The skirt is equipped with two straps to connect to the cylinder. In fact, in addition to the classic central strap, there is a second, higher up strap for a more stable and secure positioning. The main features of the skirt are: - Resistant to the most extreme conditions - Superior fit thanks to the more surrounding shoulder straps - Anatomical pocket cut to minimise water resistance when moving - Pockets with internal elastic for accessory clips - Padded backpack - Strategically placed steel D-rings
