BCD SET MONO COMFORT (Donut 15) - Tecline

The Tecline Mono Comfort BCD Set is a professional-grade modular single-tank back-mounted system designed to offer the perfect balance between ergonomic comfort, durable materials, and precise buoyancy control. Built around the proven Donut 15 buoyancy chamber with an integrated single-tank adapter, this set includes a heavy-duty stainless steel backplate, a fully adjustable harness, and a complete system of weight pockets.

Technical and Construction Specifications of the Bag:

• Design and Capacity: A double-layer bag with a capacity of 15 liters (35 lbs / 147 N). Its distinctive oval shape makes it easy to use in any position, allowing for completely unobstructed and smooth airflow for optimal trim control.
• Outer Bag: Made from special 1000D heavy-duty nylon, an extremely durable fabric that is soft to the touch, stain-resistant, and highly resistant to mechanical damage (abrasions and cuts).
• Inner Tube: An inner tube made of 840-denier nylon, a highly reliable material with enhanced resistance to aging and cracking.
• Control Unit (Inflator): Equipped with a high-quality 40-cm inflator and a 55-cm Proflex IFLP hose. The hose is positioned on the left side of the bag to prevent any interference with the tank, and its upper connection elbow is structurally reinforced by a wide strap.
• Release Valve: Equipped with a low-profile pressure relief/quick-release valve, featuring a small, highly visible red knob and specially shaped slots that facilitate rapid gas release.

Items Included in the Set:

Tecline Donut 15 Bag:

Rear tank with integrated single-tank adapter, a technical solution that allows the tank to be attached directly and securely to the system without the need for an external metal backing plate.

3 mm Stainless Steel Back Panel:

A heavy, rigid plate with extremely high strength, ideal for ensuring structural stability and distributing part of the weight evenly along the diver’s spine.

Adjustable Comfort Harness:

An anatomical, adjustable harness system that makes it much easier to put on and take off the heavy tank assembly, both on land and on board. The harness comes with D-rings that can be configured in a fixed or adjustable position, depending on your preference.

2 Cylinder Carriers:

Set of two standard high-strength straps, designed to securely and stably attach a single tank to the bag and the plate.

Set of Lead Pouch:

A pair of integrated weight pockets designed to be attached to the waist belt, ideal for modular, secure weight management with quick release in case of an emergency.

Intended Use:

The BCD Set Mono Comfort Donut 15 is an excellent choice for advanced recreational divers, guides, or instructors who want the clean lines and hydrodynamic benefits of a 15-liter single-tank back-pack, but don’t want to sacrifice the comfort of a fully adjustable harness or the convenience of weights integrated into dedicated pockets.
