Product Information

The Waterproof W4 7mm Wetsuit - Mens (Yellow) is a back-zip full wetsuit built from 100% microcell CR neoprene, with 3D-moulded vulcanized rubber kneepads, a YKK Vislon back zipper with a bronze slider, and a retro-futuristic styling that reflects Waterproof's nearly 30 years of wetsuit-making experience.

Who it is for

This suit suits divers who want a 7mm full-coverage wetsuit for warmth and durability, including dive instructors who spend extended time on their knees thanks to the 3D-moulded kneepads with a hinge-effect design for unrestricted leg movement. The pre-bent, 3D-sculpted arms and legs give an anatomical fit for a relaxed body position in the water, and the WPAD accessory dock on the right thigh lets divers add an expandable pocket for a spare mask, slate, deco tables, or a GoPro when they want extra storage, or leave it off to keep the setup streamlined.

Key details

  • 100% microcell CR neoprene throughout, bonded with HiQ Nylon thread
  • Double smooth-skin neoprene seals at the arms and legs, designed to fit Waterproof boots and gloves
  • YKK Vislon back zipper with a bronze slider, plus a separate fully gusseted comfort zipper that relieves stress on the surface
  • 10mm pre-shaped spinepad at the neck area for an extra cold-water seal
  • ToughTex reinforcement panels at the elbows and knees, plus reinforced shoulders for abrasion and anti-slip protection
  • WaveFlex arm panels in the hollow of the arms for easier movement
  • Polyurethane embossing on the seat for a non-slip grip and integrated abrasion protection
  • Moulded hook and loop fastener tab with TPU teeth for a secure, durable closure
  • Reflective label for added high visibility
  • Computer strap anchor with an anti-slip surface to keep a dive computer from slipping off the arm

Frequently Asked Questions

How should a wetsuit fit?

A wetsuit should feel snug everywhere, with no loose pockets at the lower back, armpits, or behind the knees where water can collect and flush. It will feel tighter than normal clothing on land, which is expected, because the suit works by holding a thin layer of water that your body warms. If you cannot take a full breath or the neck chokes you it is too small, and if you can pinch loose folds of neoprene it is too big.

What do you wear under a wetsuit?

Most divers wear a swimsuit, a rash guard, or a thin dive-specific base layer under a wetsuit. A slick base layer makes a tight suit much easier to pull on and cuts down chafing at the neck, shoulders, and underarms. Avoid thick cotton clothing, which soaks up water, bunches, and makes you colder rather than warmer.

How do you put on a tight wetsuit?

Work upward in small sections, pulling a little neoprene at a time rather than yanking on one spot, and get the suit fully seated at the ankles and knees before working on the hips and shoulders. A plastic bag over each foot and hand, or wetting the suit first, helps it slide into place. Grip with flat palms rather than fingertips, since fingernails are the most common cause of torn neoprene.

Does a thicker wetsuit mean a warmer wetsuit?

As a general rule, thicker neoprene insulates more, so a higher millimeter rating is warmer in the same conditions. Warmth also depends heavily on fit, suit style, seam construction, whether you add a hood, boots, and gloves, how long the dive is, and your own cold tolerance, so two divers in identical suits can feel very differently. Use thickness as a starting point and refine it against your local conditions and personal experience.

How do I care for and store a wetsuit?

Rinse it inside and out in fresh water after every dive day, and use a wetsuit-specific wash occasionally to control odor. Dry it inside-out first and then flip it, always out of direct sunlight, because UV and heat break down neoprene faster than anything else. Store it hanging on a wide-shouldered hanger or laid flat rather than folded, so you do not set permanent creases.

How long does a wetsuit last?

Lifespan depends far more on use and care than on age, so a suit dived hard in sun and chlorine may soften within a couple of seasons while a well-rinsed occasional-use suit can last many years. Signs a suit is finished include compressed neoprene that no longer feels buoyant or warm, splitting seams, and looseness in areas that used to be snug. Repairing small cuts and seam separations early adds meaningfully to a suit's life.

What is the difference between a full suit, a shorty, and wetsuit separates?

A full suit covers arms and legs, a shorty stops at the upper arms and thighs, and separates such as tops, bottoms, and hooded vests layer to add warmth where you want it. Layering a vest or top under a full suit adds core warmth and can extend the range of a suit you already own. Choose based on how much coverage you want, both for warmth and for protection against stings and abrasion.

What do the Tall sizes on the Waterproof W4 mean?

The W4 is offered in Tall sizes MT, MLT, LT, XLT, 2XLT and 3XLT+ alongside regular sizes. Contact us for Waterproof's size chart before ordering.

What is the WPAD on the W4 wetsuit used for?

WPAD stands for Waterproof Personal Accessory Dock, a docking station on the right thigh that lets you attach an expandable pocket. The pocket is large enough for a spare mask, slate, deco tables, or a GoPro, and you can leave it off when you want a streamlined setup.

Is the Waterproof W4 a front-zip or back-zip wetsuit?

The W4 is a back-zip wetsuit with a YKK Vislon zipper and bronze slider, plus a separate fully gusseted comfort zipper.

Will the W4's wrist and ankle seals work with other brands' boots and gloves?

The W4's double smooth-skin neoprene seals at the arms and legs are designed to fit Waterproof boots and gloves.
