For the past decade, my go-to wetsuit for a wide range of diving experiences has been a 3 mm women’s Aqualung, and the Aqualung HydroFlex has all the durable, trusted features of my well-worn wetsuit, plus even more to love.

With exceptional comfort, incredible stretch, and mobility on another level, the HydroFlex has made it easy for me to find a new everyday suit to rely on. It is constructed with environmentally friendly, petroleum-free neoprene and water-based glues, and supports reef conservation through Aqualung’s long-term partnership with Coral Guardian, shown off through the suit’s appealing macro coral print on the arms and legs.

Dive in to read more about the Aqualung HydroFlex and its best qualities.

Things we like:

  • Extra-stretchy neoprene for mobility and easy on and off
  • Easy to use back-zip
  • Snug and leak-proof entry points
  • Reinforced in high-abrasion areas for durability
  • Eye-catching coral print design
  • Made of petroleum-free neoprene with a PAH-free formula
  • Supports Coral Guardian, a non-profit that protects Indonesian reefs

Things we don't like:

  • It won’t suit those who want a plant-based (Yulex) neoprene wetsuit

DIVEIN's take
Why buy from Amazon?

Amazon has a documented Prime delivery program that covers millions of items, and that is the most concrete order-related support behind buying here.

Worth knowing

Some customers report slower replies or needing more follow-up than expected when they asked for help after ordering. If an order needs post-purchase support, that part of the experience is not always smooth.

Some customers also report delivery problems after ordering. That keeps follow-up and delivery as the areas to watch if you place the order here.

Aqualung HydroFlex: Do Your Toe Touches

Super stretching in Aqualung’s HydroFlex super-stretch neoprene

When they say flex, they mean all the way. The super-stretchy material in this innovative neoprene gets you up to 250% more stretch than conventional neoprene, according to Aqualung. The material is also used throughout the suit, meaning nothing will hold you back from those underwater splits we all do.

This key feature, combined with the comfort and reputation of Aqualung gear, make this wetsuit an easy top pick for most divers. The suit is suitable for water temperatures from 70 F (21 C) and warmer, and it comes in your choice of black/blue or black/white.

Genuinely, I could easily tell the difference between this super-stretch material and any other wetsuit I’ve donned. I could feel the unrestricted mobility in any direction I bent, stretched, or squatted, and relished the fact that I might even be able to do some extra-steamy hot yoga in this thing (I stuck to diving).

The stretchiness seems quite invaluable when it comes to maneuvering into and out of the suit itself, as well as into other gear on a dive boat with limited space. The same could be said for the freedom it allows underwater, with a full range of flexibility and dexterity in any situation.


Comfort and Design

The stretch and perfectly snug fit of the suit (size small for me at 5’4” and 120 lbs.), along with added features like a V-shaped collar, flatlock stitching, and well-sealed O-ring wrists and ankles, offered a snug and leak-free experience while swimming across a labyrinth of coral.

Altogether, the HydroFlex felt like an easy and comfortable standard wetsuit, complete with a trim look and striking patterns of tentacled coral polyps on the arms and legs that I will love for years to come.

The suit also has additional reinforcements in the laminated chest panel and powertex knee panels. Printed designs on the shoulders and wrists offer extra durability and resistance to abrasion, as well as helping to keep gear like wrist dive computers and BCDs in place.


Aqualung HydroFlex Materials

Aqualung uses a high quality, petroleum-free 3 mm neoprene to construct this suit, which adheres to a PAH-free formula, meaning the fabric is tested to ensure lower levels of pollutants.

It would be nice to have more readily available details for consumers on the materials used on the Aqualung product page online, rather than denoting their methods as simply “environmentally friendly,” but this is at least a criterion Aqualung is paying attention to.


Price/Quality Ratio

Coming in at a moderate $215 at the time of writing, the Aqualung HydroFlex is not the cheapest wetsuit out there, but it offers a solid, mid-range price option for a solid 3 mm wetsuit.

Because of the comfort factor, the suit’s durability, and quality of construction with non-petroleum-based neoprene, this wetsuit is worth a step up in price from a budget option in my book.

The HydroFlex is one first-rate option, but check out our full guide for comparisons and further recommendations on finding the right wetsuit for you, along with any other dive gear you may need.

Do we recommend the Aqualung HydroFlex?

With its super-stretch neoprene, superior performance, comfort underwater, and petroleum-free construction, the Aqualung HydroFlex comes with our strong recommendation.

This quality mid-range suit offers an excellent, standard go-to for a women’s 3 mm, and will continue to keep me warm and trim on a world of underwater adventures into the future.
