In addition, a corresponding lower center slot allows for lower band bolts that are misaligned. 4 upper and lower perimeter holes along either side and 4 holes along the bottom allow for the mounting of accessories and side-mount butt plate. Bended lower edges, Mares XR logos and laser cut shaped axis, highly technical pre-shape for unparalleled versatility. The back-plate has an ultra-rugged unfold-able backbone and the design was pushed to limits through intense testing. The Mares XR Aluminum Back-Plate provides total modularity: Fits all Mares donuts/wings.

The Donut Bladder Single Tank offers perfect buoyancy and trim, keeping the tank in a perfect position and maintaining comfort as well as a smooth left to right gas shift. These back inflator single tank donut bladders are built to last with a strong and durable 1200D bulletproof ballistic nylon with a 600D polyester exterior. The inner bladder is radio frequency (RF) welded black polyurethane with a heavy-duty plastic zipper and slider with elongated teeth for easy access to the internal bladder.

Buoyancy control is facilitated with the K style inflators with brass buttons equipped with a 35" (89cm) low profile, round-shaped hose and its left side position does not interfere with 1st stage regulator. In addition, trimming buoyancy when inverted is accomplished via the low-profile dump valve with micro pull cord. The low profile of the inflator, dump valve and pull cord all help prevent snagging when diving in tight spaces and in overhead environments. With the dual bag design (outer shell/inner bladder) the donut comes equipped with 6 large drain grommets, 2 on top and four on bottom to rapidly exhaust and trapped air between the outer and inner bags. These heavy-duty grommet position allows optimum trim.

Tank stabilizer body slide bars keep the cylinder perfectly aligned and nest inside the donut's wings when diving. This extremely streamlined, very stable continuous loop shape provides smooth gas shift from left to right. The XR Donut Bladder Single Tank comes in a 35 lbs. (16 kg) lift capacity. Included with the air cell is a 3/8" threaded low pressure QD hose. Finest quality materials, stylish, durable (resistant to tears, scuffs and abrasions), lightweight and long-lasting, top quality zipper: does not interfere with the woven textile tape, easy handling, strong and durable make the XR Donut Bladder Single Tank a buoyancy system for the intense diving community.
