Product Information
The Seac Black Shark Man 5mm Wetsuit is a two-piece spearfishing suit, a hooded jacket paired with high-waisted pants. Built from nylon-lined neoprene outside and open cell neoprene inside, with 7mm, 5mm, and 3mm offered for different water temperatures. It is designed for freedivers and spearfishers who need warmth, flexibility, and targeted abrasion protection for long sessions in the water.
Who it is for
This suit suits spearfishers and freedivers who want a dedicated two-piece setup rather than a single-piece dive suit, including those who load a speargun against their chest regularly and need reinforced protection there. The 5mm thickness sits in the middle of the Black Shark line, which is also offered in 7mm and 3mm, so divers can match the suit to their local water temperature.
Key details
- 5mm neoprene, nylon-lined exterior and open cell interior, glued and stitched construction
- Raw cut neoprene edging at the hood, wrists, and ankles for comfort.
- Jacket closes with a double-lock beaver tail closure using two frogs
- Sternal protection in Melco Tape material to cushion speargun loading on the jacket
- High-waisted pants with Powertex fabric reinforcement on the knees and shins
Compatibility and sizing
The Seac Black Shark Man 5mm is available in sizes Small, Medium, Large, X-Large, 2X-Large, and 3X-Large. Because the open cell interior works by suctioning to bare skin, the manufacturer recommends soaking the suit before donning it to ease entry and protect the neoprene from tearing.

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.
Is the Seac Black Shark 5mm wetsuit a one-piece or a two-piece suit?
It is a two-piece suit: a hooded jacket and separate high-waisted pants, sold together as a set.
What sizes does the Seac Black Shark Man 5mm come in?
This wetsuit is available in Small, Medium, Large, X-Large, 2X-Large, and 3X-Large. Since fit is critical for warmth and flexibility in a spearfishing suit, call or chat with DiveCatalog.com if you are between sizes or unsure which size matches your measurements.
Why does the Black Shark jacket have padding on the chest?
The jacket includes sternal protection in Melco Tape material for speargun loading.
Do I need to soak the Seac Black Shark wetsuit before putting it on?
Yes, the manufacturer recommends soaking the suit before donning it. Because the interior is open cell neoprene, which grips bare skin for insulation, soaking it first makes the suit easier to pull on and helps prevent tearing the delicate open cell fabric.
