The Mares 28XR-HR brings cutting-edge regulator technology to technical and overhead diving environments. At its core is a balanced diaphragm first stage with a double piston design, delivering consistent, high-performance airflow even at depth.

Built for harsh conditions, AST (Auto Sealing Technology) protects the first stage from sand, debris, and contaminants ideal for cave diving and polluted waters. The rotating swivel turret, featuring 4 low-pressure ports plus 1 vertical LP port, provides exceptional hose routing flexibility for twinsets, stage bottles, and sidemount configurations.

The HR second stage is constructed from ultralight technopolymer for durability without added bulk. A large, easy-to-grip side adjustment knob allows precise control of breathing effort even while wearing thick neoprene gloves.

Engineered for versatility, protection, and precision control, the 28XR-HR is built to perform wherever technical diving takes you.
