DTD Backrest Set with Adjustable Harness

DTD's constructive perfection meets maximum donning practicality without plastic components.

The DTD Adjustable set, available at DIR-STORE, is the definitive configuration for divers seeking perfect buoyancy control (trim) and the stability of a technical back-volume system, but who desire smooth and immediate donning. Unlike commercial adjustable systems, this DTD kit eliminates any structural plastic clips or buckles, entrusting shoulder strap adjustment to a geometric sliding system entirely made of stainless steel.

DTD Construction Excellence and Finishes:

The backplate and metal hardware are distinguished by an uncompromising manufacturing process:

• CNC Chamfering and Manual Polishing: All perimeter profiles of the backplate and slot holes are chamfered using computer numerical control (CNC) milling machines and then manually finished and polished. This precision eliminates the risk of fraying or cutting the harness and protects the wetsuit from any premature wear.

What the Complete Set Includes:

1. 3mm Stainless Steel Backplate

The backbone of the system, solid, rigid, and completely resistant to saltwater corrosion. It functions as an excellent fixed weight (weight ~2.22 kg) positioned exactly along the diver's center of gravity, facilitating a perfectly horizontal position in the water.

• Hole Spacing: Standard 280 mm (11 inches), universally compatible with all technical wings/donuts on the market.

2. DTD Adjustable Harness (PA Webbing)

An advanced harness system made of high-strength Polyamide (PA), optimized to facilitate donning:

• 2 Adjustable Stainless Steel Buckles: Positioned on the shoulder straps, they allow the harness to be loosened in an instant to remove the cylinder group effortlessly (ideal on inflatables or with thick drysuits) and to tighten it millimeter by millimeter once worn.
• Complete Stainless Steel Hardware: Includes D-Rings and corresponding weight stoppers made of marine-grade stainless steel for impeccably arranging primary lights, backup regulators, and pressure gauges.
• Waist Buckle: Quick-release stainless steel for a firm and secure fit at the waist.
• Retaining Bungees: Integrated on the straps to secure regulator hoses or keep backup lights in a hydrodynamic position.

3. Integrated Safety Accessories Kit (Included in the Set):

• SMB Pouch (Colored Plate Cover): Attaches to the back of the backplate to protect the diver's back from chafing and serves as a hidden housing for the decompression buoy or lift bag. It is available in various colors to customize the system's aesthetics.
• Pouch with Technical Knife: Positioned on the waist strap to ensure immediate and ambidextrous access in case of entanglement in nets or lines.

4. Complete Crotch Strap

An indispensable vertical webbing to prevent the cylinder block from oscillating and to stop the plate-wing assembly from sliding upwards during vertical ascent. Complete with a front D-ring for DPV (scooter) towing and a rear D-ring.
