Hollis SMS75 Harness Size Chart
How to measure your BCD
- Ask someone to help. Stand upright, look forward and keep your feet flat on the floor. Use a soft tape held close to the body without pulling it tight.
- Height: measure barefoot from the floor to the top of your head.
- Chest or bust: measure around the fullest part, keeping the tape level.
- Waist: measure around your natural waist between your ribs and hips.
- 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.
If you are between sizes, contact Dive Gear Australia with your height, weight, waist and shoulder measurements, plus the suit you plan to wear.
Have the sidemount harness fitted for your configuration and training requirements.

Hollis SMS 75 BCD
Hollis has become a leader in the sidemount market. It is not just a fad and not just a tool for cavers, it’s here to stay and is growing. The SMS 75 is an evolution from years of sidemount development, which started with the SMS 100.
A product that has been copied, modified and a benchmark for technical sidemount for years. Even more popular has been the lightweight SMS 50 line. These two have taken sidemount mainstream and the building blocks this new harness. While it will cater more to hardcore cave divers, SMS 75 was created to handle all environments.
Proper trim is key and the wing is designed to promote horizontal diving with increased lift towards the hips where it’s needed most and without modification. The SMS 75 will also support rear mounted tanks and reversible inflator positions.
Features
- Trapezoid shape to promote horizontal trim
- Adjustable and removable wing bungee
- Designed for cave or open water sidemount
- Cam slots for single tank and grommets at 11” for banded doubles
- Reversible Inflator & Dump assembly
- Rigging kit included: Tank bungees, SS Cam bands, SS Bolt snaps & nylon line
- Includes sternum strap & crotch strap
- Inner located elbow to avoid overhead interference
