7 Best Training and Lap Swimming Suits for Women

8 Best Training and Lap Swimming Suits for Women

Looking to suit up and hit the pool? Here’s a breakdown of the best women’s swimsuits for lap swimming and training.

Having the right swimsuit at the pool can make or break your swim workout. A women’s practice swimsuit needs to durable, comfortable, and of course, should look good.

Fortunately, there are plenty of options when it comes to women’s swimsuits that will align with your goals in the pool and your body type.

Most women’s swimsuits designed for swim practices and lap swimming are constructed of a blend of durable and high-performance fabrics. But the biggest thing to consider when picking out the right swimsuit is finding the right fit.

When your suit is too constrictive, it hampers your ability to execute your swim stroke, streamline, and use a full range of motion. Conversely, a swimsuit that is too big or baggy will chafe and slow you down.

Below are our favorite swimsuits for women according to experienced competitive swimmers, recreational swimmers, and reviewers.

Let’s dive right in!

Speedo’s line of athletic swimwear for women is extensive, from two-piece training suits to tech suits for women competing at elite swim meets.

With their long history of creating superior products for swimmers, we had to rank the Speedo Endurance+ One Piece as our favorite training swimsuit for women.

Best Swimsuit for Swimming Laps – FAQs

How do I choose the best swimsuit for swimming laps?

Here are the key things to look for when pouring over the nearly endless number of women’s swimsuits designed for swimming laps:


The cut of the swimsuit is just about everything, as a good cut means you have full range of motion along with minimal drag from reducing extra fabric.

Swimsuits with a higher cut allow swimmers to kick with full freedom in the water, and an open back helps swimmers use the shoulders and upper back unimpeded to perform arm strokes while swimming up and down the pool.


Swimsuits for lap swimming come with thin straps, regular straps, or even oversized straps. Thin straps provide great freedom of movement and are ideal for outdoor swimming as they reduce tan lines.

Thicker straps are more prone to staying in place, however, so some swimmers will opt for a regular or thick strap as they stay in place better during swim practices, which feature lots of overhead movements.

How to Choose a Womens Lap Swimming Swimsuit


Lap swimming suits are made primarily of two types of fabrics. The durability fabrics are mainly polyester and occasionally nylon. This group of fabrics are resistant to fading and stretching from chlorine. The downside of this is that suits made of 100% polyester can feel “stiff” and can be uncomfortable if not sized properly.

The second group includes the stretch and performance fabrics, namely elastane (also known as Spandex or Lycra). These fabrics are thin, stretchy, and allow swimmers to get a custom fit from their swimsuits. Because of the thinness, however, they fade faster and will stretch out.

The perfect lap swimming suit for you has the right blend of these fabrics that ensure both comfort and durability.


All of the swimsuits in this list feature a lining that provide modesty coverage. Unlined swimsuits, particularly once wet, can quickly hug the contours of the body and even become see-through. When choosing a swimsuit for doing laps, look for suits that sport an inner lining.

Can you swim laps in a two-piece swimsuit?

The best two-piece swimsuits for lap swimming are tankinis, which are designed to stay in place when swimming while also providing adequate coverage.

This is thanks to the drawstrings included with the bottom piece, a hydrodynamic top that won’t “catch” water, and more coverage compared to bikinis and other two-piece swimsuits better designed for leisure activities.

What lap swimming swimsuits last the longest?

Swimsuits that are made completely of polyester will last the longest. This fabric is awesome for standing up against pool chemicals like chlorine and also can be exposed to UV rays without fading too aggressively. Polyester, however, is a stiffer fabric and doesn’t have as much give.

For women who want a lap swimming suit that is going to fit to the shape of their body, look for a swimsuit that has a blend of mostly polyester with a splash (ha!) of elastane, Lycra, or Spandex. The latter fabrics aren’t as resilient as polyester (or a common poly substitute, nylon) and will stretch and thin faster.

The Bottom Line

The right swimsuit for swimming laps doesn’t just keep you comfortable, it helps you swim with proper technique and range of motion, provides coverage, and by extension, keeps you motivated to keep heading down to the lap pool.

Although there are a metric buttload of swimsuits for lap swimming on the market, all you need to do is find the swimsuit that has the cut you like, the right fabric blend, and the colors and/or print that you want.

To recap:

⭐ The Speedo Endurance + Women’s One Piece Swimsuit is our top overall choice thanks to its maximum durability, color options, and thin shoulder straps and open back for freedom of movement.

Sporti’s Solid One Piece Lap Swimming Swimsuit has an excellent blend of polyester and Lycra for a custom suit fit without breaking the bank.

⭐ For women who want a two-piece swimsuit for the pool, the TYR Durafast Tankini Swimsuit is fully lined, made with 100% polyester, and will stay in place while you motor up and down the pool.

Choose the right swimsuit for you and hit the pool and your next swim workout with confidence!
