Sports Bras You Can Swim In
Updated November 2026 for the NZ summer 2026/27.
Finding swimwear that supports bigger boobs can be frustrating. You want enough coverage to feel comfortable, a secure fit and straps that don’t leave your shoulders doing all the work.
So, can you wear a sports bra for swimming instead?
Yes - a suitable sports bra can double as a swim top or provide extra support underneath a swimsuit. Here’s what to look for, with examples from my range.
Can I really swim in a sports bra?
You can, but it’s worth choosing carefully. Think about the fabric, coverage, straps and how the bra fits when you move.
A bra you’ll wear for an occasional dip at the beach has a different job from something you’ll use for swimming lengths in a chlorinated pool every morning. Regular pool use can shorten a sports bra’s life, so factor that into your choice.
And if you have a bigger bust, start with fit. A swimming bra should feel secure without restricting your breathing or making it difficult to move your arms.
What makes a sports bra a good option for swimming?
Lightweight fabric without bulky padding
Heavy padding and thick cups can hold water, leaving you feeling soggy long after you’ve finished your swim.
Look for a less bulky style that gives you the support and coverage you need.
The Parfait Active D+ moisture-wicking wirefree sports bra is one of my examples. Its unpadded design offers fuller-bust support without thick foam cups, while the higher neckline gives you more coverage.
It’s a useful option to consider if you prefer wirefree support and want a bra that can work for exercise as well as summer outings.
Supportive straps and comfortable movement
Your straps need to stay put while allowing you to move comfortably. Before choosing a sports bra for swimming, reach overhead and move your arms through a swimming stroke. Check for pulling, rubbing or slipping.
Adjustable and crossback options can help you find a comfortable fit, but you don’t have to wear a racerback to feel supported.
For a softer option with wide straps, consider the ENELL LITE. It combines wirefree support with a front fastening, and its coverage makes it an option to wear as a bikini-style top.
It also works for walking, yoga, Pilates and everyday wear, so you can get use from it beyond the beach.
Secure fastenings and straps that stay where you put them
Check that the hooks, eyes and strap fittings are secure and in good condition. You don’t want to spend your swim readjusting your top.
If you prefer underwire support, the Simone underwire sports bra is another option. Its ladder-style strap adjustment lets you set the strap length securely, while the cups offer support and separation.
Simone has been discontinued, so the sizes available are my remaining stock.
Coverage you feel comfortable wearing on its own
If you’re using a sports bra as a swim top, think about how it feels when you lean forward, reach up or move around.
Check that your breasts sit inside the cups and that you feel secure around the neckline and sides. You should be able to enjoy yourself without constantly checking or adjusting your top.
You can pair a sports bra with your favourite swim bottoms - you don’t need a matching bikini set to feel comfortable at the beach.
Can I wear a sports bra under my swimsuit?
Yes, a suitable sports bra can provide additional support underneath a swimsuit.
This can be useful if you like your swimsuit but its built-in support isn’t enough for your bust.
Try the two together before heading out. Your swimsuit needs enough room for the bra without flattening your breasts uncomfortably or pulling at the neckline. Check for rubbing where the straps and seams overlap, too.
Will chlorine and saltwater ruin my bra?
- Here's the truth: chlorine and saltwater can be tough on any swimwear, including sports bras. But that doesn't mean you can't enjoy a swim!
- Just be prepared for a slightly shorter lifespan compared to a regular swimsuit.
- The good news is, with proper care (like rinsing it with fresh water after each swim, like you would do to your swimsuit), you can extend its life and enjoy maximum support in the water.
Does moisture-wicking mean waterproof?
No. Moisture-wicking describes how fabric moves sweat away from your skin. It doesn’t mean a bra repels water or is chlorine-resistant.
If you’re looking for a quick-drying sports bra for swimming, consider the whole garment—including its lining and padding—rather than relying on the moisture-wicking label alone.
