Which one suits you?
Waterproof W40

Our 5 mm shortlist leader for divers who like stretch neoprene and a useful hip pocket. A great specification cannot compensate for water flushing through a loose fit.
Get to know this model →Sherwood Scuba Men's SSMC 5mm Back Zip Wetsuit

We like its 5 mm stretch neoprene and glued, blind-stitched seams for a conventional full-suit setup. Back-zip access is less convenient if you prefer getting into a suit entirely on your own.

What the differences mean when you buy
Thickness and intended exposure
Waterproof W40
- Thickness
- 5 mm
- Intended conditions
- Temperate water, subject to fit and personal exposure needs
Sherwood Scuba Men's SSMC 5mm Back Zip Wetsuit
- Thickness
- 5 mm
Thickness is a useful starting specification, not a complete thermal rating. Fit, water movement, duration, repeated dives and individual response affect the protection required. Compare the actual suit thickness and role rather than transferring a number from an older listing. This comparison does not set a safe minimum water temperature.
Cut, entry and movement
Waterproof W40
Ask the brand about this detail before ordering.
Sherwood Scuba Men's SSMC 5mm Back Zip Wetsuit
- Cut
- Men’s; topographical graphic
- Entry
- Back zipper with long pull cord
Try the correct body cut and size, then check shoulder reach, bending and the entry arrangement. Front and back zippers can affect dressing convenience, but convenience should not override fit. Look for gaps and uncomfortable restriction. A men’s or women’s label alone does not establish that the measurements suit an individual body.
Seams, barriers and wear areas
Waterproof W40
- Material
- Ultraflex neoprene
- Storage
- Hip pocket
Sherwood Scuba Men's SSMC 5mm Back Zip Wetsuit
- Material
- Quantum Stretch neoprene
- Seams
- Glued and blind stitched
Read seam and water-barrier descriptions alongside the fit result. A pocket or reinforcement may be useful for a particular job, while a stretch-material name is not a measured flexibility advantage. Where seam details are missing, ask the manufacturer; do not treat absent research as proof that the suit lacks the feature.
A closer look at both
W40
The W40 is Waterproof’s blue 5 mm full wetsuit, built from Ultraflex neoprene and fitted with a hip pocket. It is aimed at temperate-water diving, with a close fit intended to reduce flushing. The pocket is a useful distinction from simpler full suits when you want somewhere to stow a small item without adding a separate pouch.

More about the W40 →Men's SSMC 5mm Back Zip Wetsuit
The men’s SSMC is Sherwood’s Marine Conservation 5 mm full suit, using Quantum Stretch neoprene with glued and blind-stitched seams. Abrasion-resistant knees and a rear zipper with a long pull cord are the principal practical features. The men’s version uses its own sizing and a topographical graphic rather than the women’s wave pattern.

More about the Men's SSMC 5mm Back Zip Wetsuit →Four checks before you place an order
- Select exposure protection for the planned conditions with appropriate local guidance, then compare suitable thicknesses.
- Try the actual cut and size through the movements needed to reach your equipment.
- Check the neck, cuffs, lower back and zipper area for uncomfortable restriction or obvious gaps.
- Confirm the exact model generation, especially outlet stock, and obtain size-exchange and return 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
Include any required hood, boots or other compatible exposure equipment when comparing the total purchase. A clearance suit can be good value only if it is the correct model, fits properly and has acceptable condition and return terms. Do not substitute a current premium model’s specifications for an older similarly named suit.
A replacement is easier to justify when it fixes fit, wear or a clearly assessed exposure need. A thicker suit is not automatically the more comfortable or suitable purchase. Follow the specific cleaning and storage instructions, and reassess equipment fit and configuration if changing exposure thickness.
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
Are two suits of the same thickness equally warm?
No such conclusion follows from thickness alone. Their cut, water barriers, seams, condition and fit can differ, and the diver’s exposure needs matter. We do not have a controlled thermal comparison that establishes an overall warmth winner for this pair.
Which is the better buy for this particular comparison?
A great specification cannot compensate for water flushing through a loose fit. We like its 5 mm stretch neoprene and glued, blind-stitched seams for a conventional full-suit setup.
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.
