OMS IQ Backpack Harness

OMS-115180** - Run-Out


One of OMS's signature products, the form-fitting, fast adjust OMS IQ Pack harness leads the way in comfort and durability. It comes complete with quick release clips, chest strap, shoulder pads, back pad, two corrugated hose retainers, stainless steel waist buckle, crotch strap and is capable of being utilised with or without a backplate.

The OMS IQ Pack harness balances weight across the hips and back, evenly distributing the weight of single or double tanks. The foam lumbar pad is contoured for comfort. The chest support strap provides ideal load distribution and the removable crotch strap provides stability and comfort in the water.

This BCD harness is an incredibly rugged back-mounted weight integrated modular system that offers you an incredible variety of choices to fit your precise diving needs. Choose from 30, 45, 60 and 100 lb single bladder wings, or 60 or 100 lb dual bladder wings. Pick between Aluminium or Stainless Steel back plate.

The OMS IQ Pack harness incorporates the "soft/hard" concept where the optional backplate slides in behind the back pad.

For double cylinders, we recommend either an OMS Stainless Steel backplate be used with the OMS IQ Pack. Single cylinders can be mounted with either the OMS single tank adaptor, or two cam bands (not included).

Note: If the OMS IQ Pack is purchased together with an OMS BC Wing on the same order, any required OMS Bookscrews are included.

The OMS IQ Pack can be customised with a wide range of options: Secure cumberbund, weight pockets, mask pocket, emergency deployment system, no-sag pockets etc.

The OMS IQ Pack is ideal for divers who do a wide range of diving. It can be used with a large wing with large double cylinders for technical diving, or smaller wings with single or double cylinders for recreational diving. You can even have a very light and small wing for travelling.

The OMS IQ Pack is without question the hard-core tech divers first choice when looking for comfort! This is the original and the best model of the IQ Harness.

Note from The Scuba Doctor: Many technical divers are continuous webbing fans who will tell you that you do not need a "padded" or "adjustable" harness. Try them both. We did and we appreciated (and ultimately preferred) the ability to quickly adjust the harness and the padding offered by the OMS IQ Pack and competitors like the Dive-Rite Trans-Pack or the Alpha Extreme Softpac. The main advantages to the continuous webbing harness are no failure points (plastic quick releases or ladder locks) and a lower cost than the adjustable harnesses. But if you can't get the fit or comfort dialled in with a basic harness, then an adjustable harness is the way to go. We like the OMS IQ Pack so much we use them on our hire and training gear for both recreational and technical divers, plus in our personal diving setups. So if you're not sure, come in and take one of our OMS IQ Pack setups out for a dive.
