The Tecline Donut 15 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 a few innovations to make it even better.

The oval shape of the Donut 15 is a proven design that allows for easy handling in any position with free, unobstructed airflow between the sides, top and bottom, when shifting air. It has a lifting capacity of 15kg / 33lbs for positive buoyancy at the surface. Built with special Heavy Duty Nylon 1000D, the soft 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 webbing strip is placed to the left of the wing so as not to interfere with the cylinder valve. The wing also comes with a removable integrated single tank stabilizer, which helps keep the cylinder level when used without a Standard Tank Adaptor (STA). An OPV dump valve is located in an easy to locate position, useful for releasing air when the diver is horizontal or inverted. External pass through holes allow for easy water drainage when packing up after a dive. The wing is supplied with a 55cm / 22in Proflex braided inflator hose and 2 corrugated hoses of 30cm and 40cm, with the 40cm already installed and adjustable.
