I tried on this wetsuit in our local dive shop when I was trying to decided which wetsuit I wanted to purchase. I found it at for much less than our local store. It is super stretchy, which makes it easy to get on and off. I am very pleased with this purchase.

Questions and Answers for Aqua Lung 3mm AquaFlex Super-Stretch Wetsuit:

  • Holly:

    Just got this wet suit in the 10 long fits perfect in the leg and arm length and is a perfect snug fit (thank goodness for longs) and the chest seems to fit fine however it puckers in the upper back area. Being a new diver and my first wetsuit is this ok or should I try a size smaller

    Bill  (Certified Scuba Instructor at

    No based on the fit you have the right size.

  • Gwenn:

    In checking aqua lung sizing chart I notice the sizing for women ends at up to 130#". I do believe there are some of us diving that tip the scale beyond 130#. How do we figure a wet suit that fits?

    Darrick  (Certified Scuba Instructor at

    Hello Gwenn, when you are sizing a wet suit the two most important measurements are going to be your chest/bust and waist. Height is a secondary measurement and weight is the last measurement to take into account.

  • Evy:

    Im 5 2 & 120 -125 lbs on given days. Am I considered a small 5-6 or a medium 7-8?

    Bob  (Certified Scuba Instructor at

    The most important measurements any time you purchase a wetsuit or drysuit using the manufacturer's sizing charts will always be your waist and chest/bust measurements. The suit needs to fit your torso correctly in order to do its job properly. Keep in mind there is no such thing as a comfortable wetsuit on the surface. You want it to be snug, but not cut off circulation to your extremities. The more snug it is, the thinner the layer of water your body is heating. If its too loose you will remain warm for awhile, but eventually your body won't be able to keep up with the greater amount of water flowing through the suit and you'll wind up getting cold faster. After that your height is a secondary measurement. The manufacturers realize that generally speaking your boots and gloves can overlap slightly short arms and legs, or the diver can push or roll up longer sleeves and/or arms if need be. Weight is a measurement the diver can usually ignore. It really has little to no bearing what so ever on the sizing and fit of your suit. The manufacturers do not take into account muscle being more dense than fat, so based simply on fitness levels 2 people can be the exact same size but quite different in weight. This measurement should only be used if the person is literally on the fence between 2 sizes in all categories.

  • Colleen:

    To continue Gwens question below. Your womens sizing chart still does not give measurement dimensions for sizes above L. How can I get them?

    Darrick  (Certified Scuba Instructor at

    Hello Colleen, if you go directly to the product and if you click on the size chart for Aqua Lung and scroll down to the bottom of the size chart page it lists women size all the way up to size 2XL-short for women.

  • Donna:

    I just bought the 3mm AquaFlex Superstretch suit. Ordered based on chest and waist size, and also the height. I got a 12 short. It fits good thru the chest and waist, but there is some extra room behind the knees. The arms are tight but there is a little room around the arm pit area. What scared me is how easy it slid on. Is this a feature of the wet suit or should it be hard to put on like a standard neoprene suit.

    Bob  (Certified Scuba Instructor at

    The manufacturers put the most emphasis on the fit at the torso, so if it's snug there, the rest is okay, with the possible exception of the excess under the arms. The room behind the knees isn't nearly as critical, though. One of the biggest benefits of the super-stretch type neoprene is how easy it goes on comes off. Check the suit for excess fabric around the waist and have somebody check the small of your back. They should not be able to easily grab fabric there. If they can, it sounds like the suit may be too large.

  • Justin:

    My wife is 97lbs 55", Chest 33in, Waist 27in. Which size is suggest for this wetsuit? Thank you.

    Darrick  (Certified Scuba Instructor at

    Hello Justin, going by your wife sizing she would be a size medium in the Aqua Lung size chart.

Wetsuit Care and Maintenance


There are several different types of materials used in wetsuits to achieve specific functions. It is helpful to better understand each of these materials in order to properly care for them.

Neoprene - Neoprene is the base material that virtually all wetsuits are made of. Neoprene is a type of rubber foam and is typically laminated with other materials depending on the desired function of the material.
Standard Nylon - A standard nylon outer lining is very durable against normal wear and tear. Normal care must be taken to prevent snagging, abrasion, and cuts.
Skin material - 'skin' material may be used either inside our outside of your wetsuit and often around the wrists, ankles, and neck area. This material has a rubber like appearance either being smooth or textured, and is commonly referred to as 'skin-in' or 'skin-out'. 'Skin' neoprene material is typically used in areas where a water tight seal is desired or a benefit can be derived from it's water shedding properties. Some additional care is needed to prevent cutting, or abrasion of this material. Sharp fingernails may cut this material if care is not taken.
Thermo-skin - This material may be used inside of your wetsuit. Thermo-skin material has a silver-colored smooth skin type surface. This material has beneficial heat reflective properties and also provides a sealing surface similar to standard 'skin' materials. Some additional care is needed to prevent cutting, or abrasion of this material. Sharp fingernails may cut this material if care is not taken.
X-Flex or Iso-Flex Neoprene - X-Flex and Iso-Flex neoprene are special materials designed specifically to have a much higher rate of stretch than conventional materials. Due primarily to the looser nit needed to achieve this high degree of stretch; these materials may be more prone to snagging. Velcro may also cause some light snagging and pilling of the material. Some additional care is needed to prevent excessive abrasion or snagging.
Care before the Dive:

With any of the skin surfaces including Thermo-skin, care should be taken when donning the wetsuit to not snag the interior skin surfaces with a fingernail or toenail as this material can be cut. Avoid placing your wetsuit on or near any hot surfaces.

Care During the Dive:

The exterior surface of your wetsuit is designed to withstand the normal wear and tear you might encounter during a normal dive. Abrasion against sharp rocks or other sharp objects can cut or puncture the exterior nylon surface so reasonable care should be taken to avoid these situations. Small cuts or tears can be easily repaired with wetsuit glue. Ask your dive professional for assistance.

Care After the Dive:

When removing your wetsuit, first unzip all the zippers completely. Then remove one section at a time taking care to avoid puncturing any of skin surface panels with a fingernail.
Wetsuit Cleaning:

Salt water and especially chlorine can 'dry out' the neoprene material. When neoprene material 'dries out' it looses it's flexibility. To ensure the wetsuit material retains it's flexibility for a extended period of time, it is important to thoroughly soak and rinse the wetsuit.
Soak the wetsuit in a tub of warm fresh water (not over 120°F) for at least 15-20 minutes.
After soaking, thoroughly hose off the wetsuit with fresh water
Place the suit on a thick hanger with all the zippers open to ensure maximum air circulation and complete drying.
Wetsuit Storage:

Wetsuit material can develop a permanent crease if left folded for a extended period of time. It is best to store your wetsuit laying flat. If that is not possible, you can store your suit on a hanger. Use as thick a hanger as possible to better support the weight of the suit. The thicker the suit, the heavier, and therefore the thicker your hanger should be. There are several after-market hangers available designed specifically for this purpose.
Store in a cool, dry and protected place out of direct sunlight.
Do not store your wetsuit in garage if the garage is used to park a vehicle. The exhaust emissions from the vehicle can over time deteriorate the neoprene.
Wetsuit Zipper Care and Maintenance:

Zippers are designed to be pulled closed or open in a straight line. Try to avoid pulling on the zipper pulls at an excessive angle to their intended path of travel. It is best to ask your dive buddy for zipper assistance in either opening or closing the back-zipper of a one piece back-zipped jumpsuit.

Avoid any contact with oil, gasoline, aerosols, or chemical solvents.
Do not expose any part to aerosol spray, as some aerosol propellants attack or degrade rubber and plastic materials.
Do not use any type of alcohol, solvent or petroleum based substances to clean or lubricate any part.
Do not store your equipment near any oil, gasoline, chemicals, or solvents.
