Aqualung Dimension BCD Size Chart
How to measure your BCD
- Waist: measure at the waistline shown in the diagram, rather than using the size on your jeans. Keep the tape level.
- Over the shoulder (OTS): run the tape from your waistline at the back, over one shoulder, to your waistline at the front.
- Check the BCD over the exposure suit and layers you will dive in. Adjust the shoulder and waist straps, then check that you can breathe and move comfortably with the BCD inflated.
- Use the chart for the exact BCD model. Height and weight are guides; waist and harness fit also matter.
If you are between sizes, contact Dive Gear Australia with your height, weight, waist and shoulder measurements, plus the suit you plan to wear.
Measuring guide based on Aqualung information.
Body measurements are in centimetres (cm); weight is in kilograms (kg). These are approximate fit ranges for this older BCD model. Check the fit over your diving suit.
This is a general size guide for older Aqualung BCDs. Contact Dive Gear Australia to confirm the fit for your exact model before ordering.

Keep the buoyancy cell behind you while retaining a complete fitted harness with the Aqualung Dimension BCD. The back-inflation design leaves the front of your torso open, and Wrapture support brings the cylinder close to your back. SureLock II pockets provide accessible releasable ballast for a compatible single-cylinder recreational setup.
Features and benefits
Support close to the body
The Wrapture harness positions the cylinder close to your back and distributes its load through the harness, helping reduce the feeling of the cylinder pulling away from you.
Accessible weight handling
The SureLock II pockets use a mechanical locking connection to secure removable ballast. Check that each pocket is fully engaged after loading and keep the release handles unobstructed.
Trim-weight positioning
The trim pockets let you place part of your ballast near the cylinder to help adjust your position in the water. Keep the distinction between trim ballast and the system’s ditchable weights clear.
Low-profile dump valves
The low-profile valves sit close to the BCD to reduce protruding hardware. The right-shoulder pull gives you an additional venting control; practise locating it in your complete equipment.
Rolled collar
The rolled collar cushions the upper edge where the BCD rests around your neck, helping make carrying the fitted system more comfortable.
ResisteK outer material
The ResisteK material is designed to resist fading and abrasion during regular use in diving environments. Rinsing away salt or chlorine, shade drying and inspection of high-wear areas remain part of looking after the BCD.
Hose routing and bladder retraction
Routing points through the back help keep compatible instrument hoses close to the fitted BCD. The bladder-retraction system draws the sides inward as you vent, supporting a neater profile when the air cell contains less gas. Check hose movement and control access with the full rig assembled.
Fit and configuration
Choose a size using this Dimension listing’s guide and check the harness over your normal exposure suit. Practise the back-inflation BCD’s surface and underwater handling with suitable instruction, then confirm that all controls and weight releases are easy to reach. For another back-inflation fit, compare the Aqualung Lotus women’s BCD. Ask our Hallam team for fitting advice to assess the lift required for your complete rig.
What is included?
The listed BCD with its fitted harness and inflation system. Scuba cylinder, lead weights and regulator are separate. Review the selected size and any additional items on the page before ordering.
Care, rinsing and storage
After every dive, rinse the BCD, harness, buckles and accessible fittings with fresh water, paying attention to salt and sand around the inflator, dump valves and weight-pocket releases. Follow the Aqualung manual’s procedure for the fitted inflation system, including keeping the power inflator pressurised where specified.
Dive Gear Australia recommends Gear Aid Revivex BC Cleaner 10 oz for cleaning the outer surfaces and internal air cell. It helps remove salt, chlorine and residue while conditioning suitable rubber and plastic parts. Use the dilution on the cleaner’s label and follow the equipment manual.
Rinse the air cell internally through the opening specified in the manual, using fresh water and the recommended cleaner dilution when needed. Gently rotate the equipment to reach the inside surfaces, drain through the specified outlet, then rinse until the water runs clear. Drain thoroughly before drying.
Allow the BCD to dry in the shade, then store it slightly inflated in a cool, dry place without tight folds or heavy gear on top. Before diving, check that it holds air and that inflation controls, dump valves, straps and weight releases work correctly. Follow the manufacturer’s service schedule and have leaks, sticking controls or damage checked by an authorised technician.
Choose from the variations offered above, or Ask our Hallam team for fitting advice before completing your BCD selection.
