I bought the 5 mm Aqua Flex for a dive trip off the coast of South Carolina. Even in late May the water temperature was a cool 72 degrees. I cant say the suit kept me toasty warm, but it did allow me to concentrate on the dives and not on how cold it was. I would recommend this wetsuit, but be careful using the sizing chart. I had to return a medium large for a large.

Yes, this suit is truly "super-stretch"! Seriously, its like no wetsuit I have used over the past 30 years. Here are the benefits of the stretchiness: First, no more struggle to get into the suit. Dont worry about the lack of ankle/wrist zippers, they are unnecessary with this material. Second, it conforms to your individual body contours, keeping you warm. Third, and fairly obvious, the freedom of movement in and out of the water is excellent. This is my second AquaFlex. I have a 7mm that I use for cool water (I go to a drysuit in cold water). I bought the 5mm for use in Cozumel, where I find my 3mm suit leaves me a bit chilled on the second dive (I chill easily). As to size, given the wide range available, and the flexibility of the material, you will find something that fits. After looking at the chart, if you seem to be between sizes, I recommend going to the larger of the two. Pay more attention to the height than the weight indicated.

  • katja:

    Hello, I currently dive in a 3mm 9-10 quantum stretch aqua lung wetsuite (womens)... I am looking to purchase a 5mm.. I am wondering if the sizing will be smaller at the 5mm and if I should get a 11-12 (I fit my 9-10 but not with much room). If you have thoughts, Id be gratefu. thanks!

    Hello Katja, you would be the same size in a 3mm that you would in a 5mm or 7mm if you stay with the same manufacture. Each manufacture has there own sizing chart.

  • Joan:

    I would like to swim in 60* to 75* water. Will this wetsuit keep me warm? What about gloves and shoes?

    Bob  (Certified Scuba Instructor at

    This is a fairly common suit for swimmers in cold water. Boots can make it difficult to swim, with their lessened resistance in the water, unless using fins. Gloves are typically not used by open water swimmers either.

  • Josh:

    hi im getting ready to buy my first wetsuit and i was wondering what is best wetsuit to use in the months of august to june in Florida USA cause thats the only time i can dive

    Darrick  (Certified Scuba Instructor at

    Hello Josh, your looking at a 5mm thickness suit for that time of year. When you are sizing a wetsuit or dive skin. 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 you take into account. This Aqua Lung suit is a very good choice.

  • Ann:

    What is the difference between the 2013 and 2014 Aqua Lung 5mm Aquaflex super stretch Wetsuit. And which is better the Aqua Lung above or the Henderson 5mm AquaLock Hyperstretch wetsuit. Thanks

    Arthur  (Certified Scuba Instructor at

    Hello, the only difference between the 2 years is the design. I would go with the Aqualock. It is top of the line!

Whether 5mm neoprene is for seasonal needs or year-round needs, this will quickly become your favorite suit. What’s not to like? The AquaFlex 5mm jumpsuit is comfortable, warm and looks good too! From its functional kneepads to its sharp graphics, attention to detail is evident throughout.

Wetsuit Care and Maintenance

Materials: 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.
