Divers who have entered the XR world and decided to switch to a double tank will only have to buy this donut. Its circular shape allows air to circulate easily and have the technical diver direct it towards the valves. According to your teaching guidelines, this bag offers you the option of placing the drain valve on the left or right.

The key features of the Donut Bladder Twin Tank are:
 

• Drains: 6 large grommets, 2 on the top and 4 on the bottom
• 1000D Cordura and 600D polyester exterior
• A heavy-duty plastic zipper and slider with elongated teeth
• 4 heavy-duty grommets positioned to allow optimum trim
• A stretchy, low profile, oval corrugated hose
• A K-style inflator with metal buttons
• The mid position of the inflator does not interfere with the 1st stage
• A right and left modular low profile dump valve and blinder
• Extremely streamlined - very stable continuous loop shape
