What the differences mean when you buy
Shell and construction
Waterproof D3 Ergo
- Material
- Lightweight trilaminate
Dive Rite 905 Active Series Drysuit
- Fabric
- 370 g/m² Parmasoft Active trilaminate
- Seams
- HF welded with reinforcing tape
Compare the actual shell, reinforcement and lining rather than treating all trilaminates as equivalent. Denier, fabric mass and neoprene thickness measure different things. An integrated mesh lining changes the system being evaluated, but does not establish a universal exposure limit. Durability claims need suitable testing, not just a material name.
Entry, fit and boots
Waterproof D3 Ergo
- Zipper
- Plastic dry zipper
- Boots
- Flexible neoprene
- Listed weight
- 4.1 kg, complete men’s medium
Dive Rite 905 Active Series Drysuit
- Entry
- YKK Aquaseal front zipper; telescopic torso
- Boots
- Hybrid rubber and neoprene
Fit the suit over the undergarments intended for use and check reach, bending, boot fit and entry. A quoted weight applies to its named size and configuration; do not compare it with an unweighed made-to-measure order. Front and rear entry create different dressing requirements that should be tried before purchase.
Seals, pockets and ordered options
Waterproof D3 Ergo
- Seals
- Silicone; Quick Neck and QCS Oval systems
Dive Rite 905 Active Series Drysuit
- Seals
- Latex or SI TECH rings with silicone
Write down the exact neck and wrist system, replacement parts and pocket configuration. Similar model names can use different rings and zippers. A field-replaceable seal system is useful only with the correct spares and knowledge; it does not make unrelated components interchangeable. Confirm current production changes and the options on your quotation.
A closer look at both
D3 Ergo
The D3 Ergo is a lightweight trilaminate drysuit with silicone seals, a plastic dry zipper and flexible neoprene boots. Waterproof lists a complete men’s medium at 4.1 kg, including valves, boots, seals and suspenders. The cut is slimmer through the torso and legs, with additional shoulder room, so it deserves attention from divers trying to reduce bulk.
What we like
We would shortlist D3 Ergo for a lightweight-trilaminate brief and its replaceable silicone seal systems.

More about the 905 Active Series Drysuit →Four checks before you place an order
- Arrange a full fitting over the intended undergarments, including boot and fin compatibility.
- Check the actual entry procedure and range of movement with qualified fitting assistance.
- Record the ordered seals, rings, zipper, boots, pockets and alterations in writing.
- Ask about suitable training, servicing, repair turnaround, replacement seals and warranty conditions.
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
Price the complete exposure system, including undergarments, any dry-glove arrangement, alterations and required spares. Made-to-measure and stock suits can have different delivery and return conditions. A base price comparison becomes misleading if one quote includes boots or seal systems that the other treats as options.
Changing suit construction should prompt a review of fit and equipment compatibility with qualified support. A drysuit comparison is not operational training. Follow the model’s zipper, seal and storage instructions, and avoid assuming that a repair method or spare from another model is suitable.
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.

Product details and further reading →Questions worth settling
Does the suit material tell me how warm I will be?
No. The whole exposure system, including undergarments, fit, conditions and duration, needs assessment. A shell material or nominal neoprene thickness does not provide a safe temperature limit, and we do not have a controlled thermal test establishing a winner.
Which is the better buy for this particular comparison?
Decide on latex or ring-mounted silicone seals with the supplier before comparing the final quote. We would shortlist D3 Ergo for a lightweight-trilaminate brief and its replaceable silicone seal systems.
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.
