  • Thickness: 3 / 4 / 1.5 mm
  • Design: Regular Full-Length
  • Ironman & USAT Approved: Yes
  • Other: Thinner Arms and leg holes, strategically placed super-stretch nylon

If you’re looking for a good entry level suit, then check out the Blueseventy 2019 Women’s Sprint Triathlon Wetsuit.

Perfect for open water swimming while maintaining a high level of comfort, you’ll actually enjoy wearing it. As it’s Ironman & USAT approved, you can count on it lasting through rigorous conditions, too.

As the best triathlon wetsuit for women, you can count on the brand’s Super Composite Skin (SCS) which is coated in the legs and arms to give you a protective barrier against fingernails, wetsuit strippers, and other threats to the material.

The oversized arm gussets make them super easy to move around in, with the super stretch jersey offering not only excellent flex but visibility.

The shoulders, upper chest and arms are all very stretchy and flexible, so you have a complete range of motion that won’t restrict you in your abilities.

The lowered collar is perfect because it doesn’t cut into nor chafe the sensitive skin, while the curved closure flap reduces collar height to further increase comfort.

When you’re done, you’ll love the easy-out ankles so you can quickly take it off and move to the next challenge, or go home if you’re practicing.

Synergy Triathlon Wetsuit Women’s Endorphin Sleeveless at a Glance:

  • Thickness: 5/3 mm
  • Design: Sleeveless, Full-Length
  • Ironman & USAT Approved: Yes
  • Other: 5mm Thick Core Buoyancy Panel, 680% Flexibility

Next up is one of the best sleeveless wetsuits available today: the Synergy Triathlon Women’s Endorphin Sleeveless Wetsuit.

As this one is also Ironman & USAT approved, as well as athlete endorsed, you can count on a professional level of quality in durability and performance.

Coming in a large variety of sizes, you can ensure it fits your body perfectly.

With some of the most modern technology in the game, you’ll get hydrodynamic neoprene comprised of Yamamoto #39 with SCS silicone coated SyPrene.

That is kind of a mouthful, but essentially it means that it’s made for you to go as fast as possible in the water, allowing it to roll off of you.

The 5mm thick core buoyancy panel and 3mm lower legs and back panels will also help you to perform your best and float higher.

With a full range of motion and a whopping 680% flexibility, you’ll never feel restricted. In fact, this may just be the freest you’ve ever felt out in the water.

With every single component of this wetsuit, you’ll find quality. Even the zipper is made to last you for years! You’ll find the highest-grade, anti-corrosion internal wetsuit zipper from YKK which also helps reduce drag, increasing your speed while never snagging.

An ultra-soft low neck features smoothskin on each side, which will never make you feel restricted nor like you’re being choked. Rather, you’ll forget you even have anything around your neck.

Sundried Women’s Premium Padded Triathlon Tri Suit Compression at a Glance:

  • Thickness: n/a
  • Design: Shorty
  • Ironman & USAT Approved: No
  • Other: Thinner Arms and leg holes, strategically placed super-stretch nylon

The Sundried Women’s Premium Padded Triathlon Tri Suit is perfectly crafted and precision-made for triathlon athletes.

The shorty design will give you exceptional performance, no matter if you’re just starting out or if you’re a seasoned pro. Even among the best triathlon wetsuits, this one stands out amongst the crowd.

First off, Sundried is one of our favorite brands. Not just because of the incredible quality they produce, but how everything they do is ethical.

Made specifically for swimming, cycling, and running, it’s made to fit like a second skin. This ultra-thin material is made to keep you dynamic and faster through air and water.

Not only that, but it’s made to not chafe or rub against the skin, which is going to allow you to focus on your athletic performance instead of discomfort.

The fast-drying fabric is perfect for when you need to be biking or running, and as it’s chlorine-resistant it won’t irritate your skin, nor will it break down.

In addition, you’ll find a subtle but effective hypoallergenic pad to add to your level of comfort while keeping you healthy. Smart leg grippers on the leg openings will ensure it always stays in perfect place, no matter what you’re doing.

SLS3 Women’s Triathlon Suit FX at a Glance:

  • Thickness: n/a
  • Design:Shorty/Sleeveless
  • Ironman & USAT Approved: No
  • Other: Safe pocket in rear for bars/gels, no built-in bra (use your own), sweat-wicking

If anyone is good at engineering, it’s the Germans. That’s why we weren’t surprised when we fell in love with the style and technology that the SLS3 Women’s Triathlon Suit FX offers.

This unique design has easily remained at the top of our favorites, as well as countless other athletes due to the comfort and quality that’s hard to compete with.

The design itself stands out, with a black body and either Bright Rose or Martinica Blue accents along the edges.

You get a shorty/sleeveless design that works perfectly for biking, running, and of course, swimming.

This model allows for complete control and flexibility over your body without having to worry about being restrained by your clothing.

For your comfort, they’ve added in a custom foam-cushioned pad that will give you extra protection and durability during bike rides. The good thing is it hardly adds any weight to the suit and is practically impossible to tell there’s a pad.

This best swimming wetsuit is made up of a flex fabric blend which stretches in all directions to provide support without itchiness or chafing.

The legs are long enough to prevent this, while the soft grippers keep the suit in place without being too tight. As opposed to many others, the Trisuit has a “BYOB” philosophy:

Bring Your Own Bra. The reason behind this choice is so you can choose the sports bra that works best for you.

Finally, we really appreciated the added back pocket which is easily large enough for you to securely store your energy gels, bars, and chews.

NeoSport Sleeveless Triathlon Wetsuit at a Glance:

  • Thickness: 5/3 mm
  • Design: Sleeveless, Full-Length
  • Ironman & USAT Approved: No
  • Other: Adjustable Velcro collar, reinforced spot taping

As one of the best wetsuits for open water swimming, the NeoSport Sleevless Triathlon Wetsuit is made to last and provide you with incredible protection and comfort.

Made with Advanced Wetsuit Technology, this suit will allow you to perform your absolute best, and in some cases even boost your performance.

No matter if this is your first time or you’re a veteran to triathlons, you won’t regret getting this one.

Made with exclusive speed skin neoprene, we were hard-pressed to find a more lightweight suit. Not only does this make it more comfortable, but it allows you to travel faster.

Not only that, but the special coating it comes with provides buoyancy, flex, and added comfort. This means less drag so faster times for you.

The sleeveless design provides you with a full range of motion, while the 5mm neoprene on the chest panel and 3mm back panels help with your stroke while even further reducing drag.

An anatomical cut ensures a natural fit, moving as you do, while the skin-in collar helps to both lock out water and prevent scooping.

The mid-calf openings provide a bit more protection than the shorter alternatives, while the easy-out zipper makes it quick and easy to transition.

After all, you shouldn’t have time added on with something that has nothing to do with athletic skills, right?

Made with tough YKK zippers along with reinforced stress areas and sewn/glued seams, you can rest assured this suit will last you many triathlons to come.

How to Choose the Best Swimming & Triathlon Wetsuit

 Best Swimming & Triathlon Wetsuit

Now that you’ve had the opportunity to read all about women’s triathlon wetsuits, which one will you be using in the future?

If you’ve still not made a decision or are stuck between a couple different products, that’s okay. That’s actually why we’ve decided to go ahead and create the comprehensive buying guide, below.

This guide will lead you through every step of the selection process, so you don’t have to worry about if you made the right choice. By the time you’re done, there will be no doubt as to which is the suit for your athletic endeavors.


It doesn’t matter how cutting-edge the technology is or how durable the suit is if it doesn’t fit you correctly. This is undoubtedly the most important aspect in buying the right wetsuit for triathlons, open water swimming, biking, and just about any situation.

A loose-fitting or improperly-fitting wetsuit will leave you carrying around extra weight in water while you swim which will undoubtedly slow you down, aside from just being outright uncomfortable. Look for a solid fit and seal, particularly around your neck, wrists, and legs/ankles.

If you’re still unsure, then we highly recommend taking a look at the various manufacturers’ sizing charts so you can have a good concept of how the design is cut and how well it works with your individual body measurements.


While it’s not an absolute rule, there seems to be a trend where the highest-quality triathlon wetsuits are made out of closed-cell neoprene. What is closed-cell neoprene?

It’s neoprene which is lined on the interior surface with a fabric like nylon, polyester, or more modern quick-dry materials. Closed-cell neoprene doesn’t stick to the skin, letting water move freely between you and the wetsuit.

This also makes them much easier to put on and take off, which is ideal when you’re dealing with time constraints in a triathlon.

Thickness will typically vary anywhere between 1.5mm and 5mm. You will find some models that go thicker than that, but anything more than 5mm isn’t usually legal more triathlon races.

You’ll want a suit that’s thin and flexible, anyway – particularly around the shoulders and arms to allow for quick movements with a full range of motion so you’re not restricted, which can greatly inhibit your skills. The chest and leg areas are typically going to be thicker which will help keep you buoyant in the water.

You may also find paneling around the shoulders, arms, chest, and thighs. These panels are designed to help you breathe easier while also allowing you to pull off better and smoother strokes.

This kind of goes hand-in-hand with choosing the proper fit, but is still a bit different. After all, some people don’t judge a proper fit off of whether or not it’s comfortable, but solely if it will provide the best performance.

We’re firm believers that the best performing wetsuit is also that which provides you with the best feel. Performance fitting suits are often too tight, and we never want discomfort – nor do we want gaps or loose-fitting areas as they can cause chafing. You want it to be somewhere in-between too tight and too loose.

Also keep in mind that a loose wetsuit is just going to become even looser once it’s been in the water and been worn.

Neoprene is a very stretchy fabric which relaxes in the water, so if you’re training in it you do need it to be relatively tight. A looser suit is going to be more likely to carry water which will create drag and lower your performance level.

We have both types on our guide, so which is better? There is no “better” when it comes to triathlons; it’s all up to your own personal preference.

There are many manufacturers and users who claim that sleeveless models allow for a wider range of motion which will thus make you faster. This depends on the suit, though. There are many sleeved models which provide just about the same amount of flexibility and freedom.

Sleeveless suits are more geared towards warmer water use, though sleeved wetsuits are overall more popular.

Special Features

In all honesty, the wetsuits on our guide all carry quite a few similar features. What really starts to make them stand out are the special features which on their own may not be your reason for buying them, but when you add them all together may sway you towards one over another.

Look for things like coated rubber, breakaway zippers, reverse zippers, special panels, or pockets to keep your bars and gels. These can greatly impact your performance in a positive way, and that’s what we’re looking for, right?

Experience Level

It’s important to note that you may want to select a particular suit depending on your experience level.


If you’re just starting out, you’ll want a suit that can hold up to regular training, provide you insulation, as well as a basic range of motion. Seams should be quite tough but never chafe against your skin. They’re not the most comfortable, but they’re not a pain to wear, either. If you’re a beginner, we’d highly suggest going for the Blueseventy (#1 on our guide).


Moving up a level, you’ll get an improved range of motion as well as more flexible materials on notable pressure points so you can move freely. You may also find some extra features to help you take off the wetsuit faster during transitions.


These will allow just about the most perfect fit possible for you. They offer comfort and durability while coming in a sleek and minimal package. You’ll have the greatest range of motion with these, and will typically have the highest-quality material with cutting-edge technology. Seams will be as perfect as humanly possible.


How much are you willing to spend on your swimming wetsuit? It’s really a good idea to have this number in mind before you start shopping and make sure you don’t go over it.

However, it’s also important to remember that this is going to be a good investment if you’re serious about being a triathlon athlete. If you want to make your best time yet, then spending a bit more is typically going to be worth it.

FAQs About Wetsuits

Q: How should I put on my wetsuit to avoid damaging it?

1. Slide your feet into the wetsuit, putting leg openings a good amount above the ankle bone.

2. Fold the wetsuit inside out wo you can pull from the inside which will help eliminate the chance of tearing the neoprene.

3. Slowly work the wetsuit up to the crotch area and ensure seams are placed correctly.

4. Roll the wetsuit above the waist and smooth out any wrinkles, putting on one sleeve at a time. Push one hand out of a sleeve and use the other to push the sleeve up past your wrist and over your shoulder. Repeat for the other.

5. Bend forward to grab the material around your stomach, pulling it towards your neck.

6. Zip the back and secure the neck strap.

Q: What happens if one size if too small and the next is too big?

A: Keep in mind that a wetsuit is going to be pretty tight when you first put it on. As previously mentioned, it’s important to remember that wetsuits are going to loosen up, and will also get looser once you start training in them. With that being said, you should generally opt for the smaller size so long as it’s not causing you serious discomfort or pain.

Q: How should I store my wetsuit?

A: Try your best to stow it away without folding or creasing it in any way. The best way to do this would be to put a newspaper or something around it, avoiding the use of hangers if you can as this can also leave creases. Also make sure you rinse it out and dry it before putting it away for longer periods of time.

Q: How can I travel with my wetsuit?

A: Again, try to avoid folding or creasing it as much as you can. If you must fold it, place it away from any sharp or hard objects to avoid any kind of damage towards it.

Tips For Choosing Women’s Swimming & Triathlon Wetsuits

#1: If you’re going to be swimming in cold water, go for a fullsuit.

These are the suits which have full-length sleeves and legs. They offer more protection from the cold. Keep in mind that if you’re going for particularly long distances, these may make you overheat.

#2: Make sure your suit has added buoyancy.

This feature will give you more lift so you don’t have to try as hard to keep afloat, basically. This will lower your heart rate so you can focus on swimming faster and more efficiently.

#3: Consider longevity and durability when choosing your triathlon suit.

It’s not always the best idea to opt for the most popular brand, as many times they don’t last very long. Instead, go for a more reputable brand which have been around for years and essentially proven how durable they are. It’s never a bad idea to take a look at the warranty on your prospective suit, either.


Now that you’re practically an expert when it comes to choosing the best swimming & triathlon wetsuits, which is the one for you?

While each of the aforementioned products are the best models on the market today, what’s most important is that you select the perfect product for your athletic needs, experience level, and individual body. We hope that this guide has helped you to do exactly that.

Thanks for tuning in and we’ll see you again soon.
