Product Information

The Aqualung HydroFlex 3/2mm Shorty is a men's short-sleeve, short-leg wetsuit built for warm-water diving, snorkeling, swimming and watersports, combining 3/2mm neoprene for core warmth with a back-zip entry and flatlock seams. It is offered in eight sizes, XS through 3XL, so it suits travel-friendly dive kits.

Who it is for

This shorty is for divers and snorkelers working in tropical and temperate water who want thermal protection without the bulk and heat of a full suit. The cut keeps the shoulders, arms and legs free, which makes it a practical choice for pool training, surface watersports, boat days in the tropics and as a packable layer in a travel bag. If you dive mostly in warm conditions, a 3/2mm shorty is quick to put on, rinse and dry.

Key details

3/2mm neoprene construction for core warmth with unrestricted movement.
Short-sleeve, short-leg shorty cut for tropical and temperate conditions.
Flatlock seams for comfort against the skin and durability through repeated saltwater and freshwater use.
Back zipper entry with an extended pull cord for easier donning and doffing.
Adjustable hook-and-loop collar to help reduce water flushing at the neck.
Neoprene free of petroleum-based PAHs and water-based lamination adhesives.

Compatibility and sizing

Sizes run XS, S, M, ML, L, XL, 2XL and 3XL, including the ML size for divers between Medium and Large. A shorty should feel snug everywhere with no loose pockets at the lower back, armpits or behind the knees, since trapped water flushes and cools you. The adjustable collar lets you fine-tune the neck closure once the suit is on.

DiveCatalog.com is an authorized AquaLung dealer and a real dive shop in Irvine, California since 2003. If you are between sizes or want help deciding between a shorty and a full suit for your usual water, call or chat with us at 888-701-4017 and we will walk you through it.

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 sizes does the Aqualung HydroFlex 3/2mm men's shorty come in?

It is offered in eight men's sizes: XS, S, M, ML, L, XL, 2XL and 3XL. The ML size is useful if you fall between Medium and Large. Because a shorty works best when it is snug with no loose pockets of water, call or chat with us if your measurements straddle two sizes.

Is a 3/2mm shorty enough for warm-water diving?

This HydroFlex shorty is designed for warm-water diving, snorkeling, swimming and watersports where you want core warmth without bulk. The 3/2mm neoprene covers the torso with short sleeves and short legs, leaving the forearms and lower legs exposed, so it fits tropical and temperate conditions and pool training. For longer or cooler dives, many divers step up to a full suit or add layers instead.

How does the HydroFlex shorty zip up?

It uses a back zipper with an extended pull cord, which simplifies donning and doffing. The adjustable hook-and-loop collar then tightens at the neck to limit water flushing. This combination makes the suit quick to put on and take off between dives or watersports sessions.

What makes this shorty a more environmentally considerate wetsuit?

The HydroFlex shorty uses neoprene free of petroleum-based PAHs along with water-based lamination adhesives. Those material choices are part of Aqualung's more environmentally considerate construction for this suit. Everything else about the build, including the flatlock seams, is aimed at comfort against the skin and durability through repeated use in saltwater and freshwater.
