How Ocean Reef measures
It is essential to choose a suitable size. You can choose between size S/M (for adults with smaller faces, women and children over 12 years old) and size M/L (for an adult male, or larger faces).
- Nose bridge to chin: Measure the distance between the bridge at the top of your nose and the bottom of your chin.
- Try-on: There are two different size categories on the chart: Small/Medium and Medium/Large. If the measurements fall within the both ranges, then the diver should technically be able to wear either full face mask (M/L or S/M), and in that case should try on a mask to select the best fit. Once the mask is tight on your face, if there is NO SPACE between your chin and the silicone skirt of the mask, you've got the right size.

Product Information
The Ocean Reef Neptune Space IRON Mask is a Chem Haz rated integrated full face dive mask built for divers working in contaminated or hydrocarbon laden water, pairing a pneumatically balanced, on-demand second-stage regulator with an AISI 316 stainless steel frame and an FVMQ rubber face seal for chemical resistance. Total mask weight is 1090 g (2.40 lb) with only 172 g (0.40 lb) of positive buoyancy, and it ships with a Surface Air Valve (SAV) that lets the diver breathe ambient air without removing the mask.
Who it is for
This IDM is designed for diving in contaminated or hydrocarbon-laden water environments, with a Chem Haz rating and chemically resistant materials. It is offered with either an INT (Yoke) or DIN first stage, so divers can match it to the cylinder valve configuration they already use.
Key details
- Regulator cover in Anodized Anticorodal aluminum; frame, buckles (FRB II fast-rotating system), and adjustment knob in AISI 316 stainless steel.
- FVMQ rubber face seal, inhalation diaphragm, exhalation valve, and purge button for resistance to contaminated water.
- Polycarbonate visor with siloxane scratch-resistant coating, 92% light transmission.
- Patented 3-D equalization system, four-directional adjustable exhaust valve, Dive/Pre-dive (Venturi) lever, and six-strap head harness.
- SL35TX first stage rated to 232 bar, balanced diaphragm design with anti-freeze kit, brass chrome-plated body, stainless steel piston and spring, Teflon seat, 2 high-pressure ports (7/16-20 UNF) and 4 low-pressure ports (3/8-24 UNF), flow rate of approximately 4800 l/min at 140 bar.
- Backed by a lifetime warranty with free annual service for 4 years from the purchase date at Ocean Reef facilities.
Compatibility and sizing
This listing is the Medium/Large size in Red/Gold/Steel, available with either the INT or DIN first stage. An Extender Frame and Kit cannot be mounted on this mask unless the clamping band is switched to nylon; ask for a quote on that swap when ordering.
