Mares XR Doubles Donut wings utilize a 360 degree toroidal shape bladder design that provides an even volume of inflation on top, sides and bottom, which improves buoyancy control and promotes an efficient, horizontal trim. Available in { 44 lb | 20 kg} lift and { 52 lb | 24 kg} lift versions.

Features of the Mares XR Doubles Donut wing:

• Two pairs of webbing reinforced stainless steel grommet holes on 11-inch centers to allow assembly on doubles at your optimum height for trim.
• Heavy-duty polyurethane inner bladder is pinch and puncture resistant.
• Fabric outer shell (1200 Denier ballistic nylon on diver's side and 600 Denier polyester on exterior) with six large stainless steel grommet drain holes (2 on top and 4 on the bottom).
• Plain 90-degree elbow is positioned at the upper middle of the bladder so as not to interfere with the regulator first stages on the doubles manifold.
• Quality K-style oral/power inflator features two power inflation speeds (standard and turbo) with chrome plated brass buttons. This wing's new inflator is NOT affected by the March 2019 voluntary recall of previous models.
• Crushproof {16 in | 41 cm} low-profile corrugated hose along with a {23 in | 58 cm} rubber low-pressure BC hose.
• Combination over-pressure and pull-to-dump low profile valve on the divers right side, but the dump can optionally be moved to the left side by swapping the left side blanking plug to the right side.
• Black with grey stripe and embroidered Mares XR logo

Assembled with the combination over-pressure and pull-to-dump low profile valve on the divers right side, there are two modular fittings on the wing at both the lower bottom left and right sides. This allows the diver to swap the blanking plug and the pull-to-dump valve to either side depending on their preference.
