We’d pick the TLS350 - DUI Drysuit.
Our pick is DUI TLS350 - DUI Drysuit. Our choice for divers who value a configurable trilaminate suit and telescopic fit.
Which one suits you?
Waterproof D8 ORIGO
We like the front-entry layout, telescopic torso and lighter-style boot arrangement as a straightforward shell-suit package. Its latex seals are a different ownership proposition from the replaceable silicone systems elsewhere here.

What the differences mean when you buy
Shell and construction
Waterproof D8 ORIGO
- Material
- Poly 300D trilaminate
DUI TLS350 - DUI Drysuit
- Material
- Nylon / butyl rubber / nylon trilaminate
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 D8 ORIGO
- Entry
- Curved YKK Aquaseal #10 front zip
- Fit adjustment
- Telescopic torso and suspenders
- Boots
- Xlite Flexboots
DUI TLS350 - DUI Drysuit
- Entry
- Front diagonal or shoulder-entry options
- Zipper
- YKK metal
- Torso
- Telescopic with internal waist adjustment
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 D8 ORIGO
- Seals
- Latex neck and wrist seals
DUI TLS350 - DUI Drysuit
- 2026 specification
- Two leg pockets included; confirm order configuration
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
D8 ORIGO
The D8 Origo is a front-entry trilaminate drysuit with a telescopic torso and suspenders. It uses Poly 300D fabric, latex seals and a curved YKK Aquaseal #10 zipper. Cordura knee reinforcement, lightweight pockets and Xlite Flexboots keep the specification focused on the main suit functions rather than the interchangeable silicone systems of some other Waterproof models.
What we like
We like the front-entry layout, telescopic torso and lighter-style boot arrangement as a straightforward shell-suit package.
What would make us think twice
Its latex seals are a different ownership proposition from the replaceable silicone systems elsewhere here.
More about the D8 ORIGO →TLS350 - DUI Drysuit
The TLS350 uses nylon/butyl-rubber/nylon trilaminate and is offered with different entry, boot and seal configurations. Its telescopic torso and waist adjustment help tailor the fit around insulation. DUI now lists two leg pockets as included for 2026, a detail worth checking when comparing current orders with older stock or second-hand examples.

What would make us think twice

More about the TLS350 - DUI 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.
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?
Entry, seals and boots need to be agreed on the order; the name does not describe one fixed package. We like the front-entry layout, telescopic torso and lighter-style boot arrangement as a straightforward shell-suit package.
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.
