Aquawing Max is the one-size donut jacket designed to adapt to all anatomies (male and female) using the new patented MAS (Modular Adjustment System): in fact, the single 50 mm belt that embraces the shoulders and waist can be rapidly adjusted to your size. The shape of the air bladder has been designed to ensure perfect buoyancy with a monocylinder. The anodized light alloy back plate reduces the overall weight of the jacket while guaranteeing stability and safety in use. The special cylinder rest in thermoplastic rubber integrated with the back of the jacket guarantees the positioning of the tank for optimum trim. The shoulder straps and back cover are made with an air-net material to enhance comfort and improve water drainage. The back cover is equipped with a special pocket designed to house the decompression buoy One-size-fits-all (xs / xl) Air bladder: 210 d nylon Air bladder cover: 1500 d cordura Modular adjustment system MAS - easy to adapt 4 stainless steel D-rings Volume: 17 liters Rear trim weight pockets included - max. 2.5kg per pocket Weight bags included - max 3 kg per bag
