The Tecline Donut 13-wing is a classic design for single-tank divers who believe: "If it ain't broke, don't fix it." Tecline has kept the design, made it more durable and added some innovations to make it even better.

The oval shape of the Donut 13 is a proven design that allows for easy operation in any position with free unobstructed airflow between the sides, top and bottom, when shifting the air. It has a lifting capacity of 13kg / 29lbs for positive buoyancy on the surface. Built with special Heavy Duty Nylon 1000D, the soft outer shell is extremely durable and resistant to abrasion. The quality YKK zipper reveals an internal bladder made of Nylon 840 with high resistance to aging and cracking. A reinforced inflator elbow loop with wide strip strip is placed to the left of the wing so as not to interfere with the cylinder's tap. The wing also comes with a removable integrated stabilizer for a single tank, which helps keep the cylinder level when used without a standard tank adapter (STA). An OPV dump valve is located in an easy to locate position, useful for releasing air when the diver is horizontal or upside down. Exterior grommet holes allow for easy water drainage when packing up after a dive. The wing comes with a 55 cm / 22 inch Proflex braided inflator hose and 2 ribbed hoses of 30 cm and 40 cm, with the 40 cm installed and you can adjust it.

Tecline's wings are fully compatible with most backplates from other manufacturers, as long as there are mounting holes on the backplate with a spacing of 28 cm / 11 inches (center to center of the grommet opening), for mounting with a single tank adapter (STA). They can also be used without STA, by threading a tank strap through the slots on both the wing and backplate.
