Product Information

Who it is for

This 3mm suit suits divers who want a flexible, snug-fitting wetsuit built around four-way stretch neoprene for ease of movement. As a general guide, thinner neoprine like this 3mm option is suited to warmer water, while the Aquaflex line also offers 5mm and 7mm suits for cooler conditions. The Canadian cuff and semi-dry zipper system are part of this suit's construction.

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 is Aqua Lung AquaFlex neoprene?

AquaFlex is Aqua Lung's 4-way stretch, petroleum-free neoprene. The line describes it as offering three times the stretch of standard neoprene, which makes the suit flexible and easy to move in. It is used across the Aquaflex fullsuit range.

What thicknesses does the Aqua Lung Aquaflex come in?

The Aqua Lung Aquaflex is offered in 3mm, 5mm, and 7mm. As a general guide, thinner suits are better for warmer water and thicker suits for cooler water, though your own cold tolerance and dive conditions matter too. The 5mm and 7mm add extra water-entry protection compared with the 3mm.

How does the Aqua Lung Aquaflex keep water out?

The Aquaflex uses several features to limit water entry. Its seams are sealed with liquid rubber, and the 5mm and 7mm versions add a semi-dry zipper along with Canadian-style cuffs and seals that reduce flushing. Powertex reinforcement at the knees adds durability.

What sizes does the Aqua Lung Aquaflex come in?

The men's Aquaflex size chart lists S, M, ML, L, XL, 2XL, and 3XL, with a separate women's range. If you are between sizes, send us your measurements and we will size you.

What color does the Aqualung Aquaflex 3mm wetsuit come in?

The men's Aquaflex 3mm wetsuit is offered in Black/Chine Grey. It is available in sizes S, M, ML, L, XL, 2XL, and 3XL, so you can match the color and size to what's in stock in your fit.

Does the Aqualung Aquaflex 3mm wetsuit have a semi-dry zipper?

Yes. The Aquaflex 3mm features a semi-dry zipper system, along with a Canadian cuff and Powertex knee protection.

Is the Aqualung Aquaflex 3mm wetsuit good for warm water diving?

As a general guide, thinner neoprene suits warmer water. The Aquaflex line also offers 5mm and 7mm versions for cooler conditions.
