We’d pick the IQ LITE CB Harness w/ Cummerbund Package.
Our pick is OMS IQ LITE CB Harness w/ Cummerbund Package. Our wing-style choice for a single-cylinder diver who wants a cummerbund rather than bare webbing.
Which one suits you?
Atomic Aquatics BC2
Our preference of the two Atomic layouts for buyers who want back inflation. A separate inflator adds another decision and cost to the complete setup.

What the differences mean when you buy
Fit and inflation arrangement
Atomic Aquatics BC2
- Inflation layout
- Back inflation
OMS IQ LITE CB Harness w/ Cummerbund Package
- Harness sizes
- XS, S, M/L, XL
Fit the actual BCD or harness over the exposure equipment you intend to wear. Check reach to controls, releases and pockets and have the cylinder arrangement assessed. Jacket, back-inflation and separate-wing packages can differ in adjustment and layout; the largest lift number does not establish the most suitable recreational BCD.
Lift and ballast systems
Atomic Aquatics BC2
Ask the brand about this detail before ordering.
OMS IQ LITE CB Harness w/ Cummerbund Package
- Wing options
- Performance Mono 27 or 32 lb
- Ballast capacity listed
- 6 lb per side
Keep lift, ballast capacity and release function separate. A rear weight pocket is not automatically an equivalent releasable main pocket. Some models vary by size or release system, so record the exact configuration. Required lift and ballast should be assessed for the full equipment setup rather than chosen by filling the maximum stated capacities.
Dry weight, storage and supplied parts
Atomic Aquatics BC2
- Inflator assembly
- Sold separately
OMS IQ LITE CB Harness w/ Cummerbund Package
- Tested package weight
- 3.4 kg in the DIVER review
Compare dry weights for the same size and included components. A reviewed wing package may include parts that a current base listing does not. Check the inflator, pockets, mounting accessories and cylinder attachment in the quote. Higher fabric denier is a specification, not a standalone durability test across complete BCDs.
A closer look at both
BC2
BC2 is the back-inflation model in Atomic’s BC range. The manufacturer provides several sizes and states that the inflator assembly is sold separately.
What we like
Our preference of the two Atomic layouts for buyers who want back inflation.
What would make us think twice
A separate inflator adds another decision and cost to the complete setup.

More about the IQ LITE CB Harness w/ Cummerbund Package →Four checks before you place an order
- Arrange a fitting with the intended exposure suit and cylinder setup, including access to every control.
- Record the exact size, wing or bladder and release-system variant.
- Confirm assessed lift requirements and which ballast pockets are releasable; have the release system demonstrated.
- Get the complete package list and weight, including any separately sold inflator or accessories.
Ask for a quote for the complete kit, including the accessories you need. That makes the price comparison much more useful.
Price, accessories and owning the equipment
Compare the price of a ready-to-dive package. Include the inflator, ballast pockets and mounting hardware you need. A tempting body-only price can look quite different once the missing pieces are added.
For travel, weigh the complete BCD in your size. We would choose a comfortable, suitable setup over extra lift or rescue features we would never use.
How we scored these models & further reading
These are our subjective buying scores out of 100. We weigh the usefulness of the features, the intended diving or carrying job, and the compromises involved in owning the gear. They are not laboratory measurements, safety grades or customer averages. The verdict applies to the two named models, not everything either brand makes.
90–100: one of our first choices for the stated job. 80–89: a strong option with trade-offs. 70–79: a more specific fit. A different fit, camera, valve or dive plan can change which one you should buy.

Questions worth settling
Should I buy the BCD with the most lift?
Not simply because the number is larger. Fit, the intended cylinder and exposure configuration, control access and suitable assessed lift all matter. The stated capacity cannot by itself establish whether a BCD is appropriate for your setup.
Which is the better buy for this particular comparison?
Check which 27 or 32 lb wing and ballast components are included in the quoted package. Our preference of the two Atomic layouts for buyers who want back inflation.
Our pick is where we would start. Choose the other model if its fit or features better match your setup—especially where a camera, valve, boot or exposure suit needs an exact match.
