Product Information
The AKONA 7mm Quantum Stretch Full Suit - Men's is a cold water full wetsuit built with AKONA's Quantum Stretch construction, pairing a proprietary four-way stretch nylon weave with lightweight, limestone-based neoprene for flexibility in all directions. It uses a saltwater resistant back zipper and flush-cut glide skin seals, and is offered in nine men's sizes from SM to 5XL.
Who it is for
This suit is for the male diver who dives cold water and wants 7mm neoprene with AKONA's four-way stretch Quantum Stretch construction. The back zip entry is the familiar, easy-to-manage style for divers who suit up with a buddy. AKONA classifies it as a cold water suit, so it suits divers who want maximum neoprene thickness for cold conditions. The size run through 5XL also makes it a practical choice for larger divers who struggle to find a 7mm full suit that fits snugly.
Key details
- Thickness: 7mm, classified by AKONA as a cold water suit.
- Material: Four-way stretch nylon weave laminated to lightweight, limestone-based neoprene rubber.
- Entry: Back zip with a saltwater resistant zipper.
- Seals: Flush-cut, glide skin seals at the openings to limit water flushing.
- Sizes: SM, MD, ML, LG, XL, 2XL, 3XL, 4XL, 5XL.
Compatibility and sizing
Nine sizes are published for this AKMS539 series, including the ML (Medium Large) intermediate size that helps divers who fall between Medium and Large. A 7mm full suit should feel snug everywhere with no loose pockets at the lower back, armpits, or behind the knees, and it pairs naturally with a hood, boots, and gloves for cold water dives.

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 AKONA 7mm Quantum Stretch Full Suit warm enough for cold water diving?
Yes. AKONA classifies this 7mm suit as a cold water suit, and it has flush-cut, glide skin seals. Warmth also depends on fit, dive length, and accessories, so most divers in cold water pair a 7mm full suit with a hood, boots, and gloves for longer or repetitive dives.
What makes Quantum Stretch neoprene different from standard neoprene?
Quantum Stretch uses a proprietary lamination process that bonds a four-way stretch nylon weave to lightweight, limestone-based neoprene rubber. Unlike standard neoprene, this construction stretches in all directions and is built for harsh diving conditions.
What sizes does this AKONA men's 7mm wetsuit come in?
The AKMS539 series is published in nine men's sizes: SM, MD, ML, LG, XL, 2XL, 3XL, 4XL, and 5XL. The ML (Medium Large) size is useful if you fall between a Medium and a Large. If you are unsure which size to order, call DiveCatalog.com at 888-701-4017 and we will walk through your measurements with you.
Does this suit have a back zip or a front zip?
It is a back zip full suit, listed by AKONA as the Men's Classic Line 7mm Back Zip. The zipper is saltwater resistant.
