Nike's Best Wireless Bras

An underwire bra has its benefits—it helps provide lift, support and shape—but it may not feel right for every person or every occasion. Though Nike sports bras with underwire offer a boost of definition and can help contain extra movement, wireless sports bras come in all support levels, fabrics and fits to help you navigate your day, no matter what gets thrown your way.

Here are Nike's top picks for wireless bras, along with a few tips on how to choose the right one for you.

Light-Support Wireless Bra: Nike Indy

The adjustable straps and removable padding make the Nike Indy customisable. The bra comes in a range of styles from high-neck or scoop-neck, strappy-front to cut-outs and even zip styles.


If you want to showcase the strappy back of this low-impact, wire-free bra, try it with an open-back yoga top. If you're wearing it to sweat, opt for the Nike Dri-FIT fabric option, which is designed to disperse moisture across the surface of the bra for speedy evaporation. Or throw on this soft, breathable, everyday bra before running errands (or lounging on the sofa).

Medium-Support Wireless Bra: Nike Swoosh

If you're looking for a bit more support, try out the Nike Swoosh. These bras have wide straps, moderate coverage and stretchy fabric that keeps you in place. Non-padded and one-piece removable-pad styles are available and most Nike Swoosh bras are made using Dri-FIT Technology to wick moisture away from the skin, making this a reliable option for a range of workouts and activities.

Plus, as part of the maternity collection, Nike (M), Nike makes a nursing bra designed with discrete layers to make feeding or pumping a bit easier, with a special moisture-managing fabric for nursing.

High-Support Wireless Bra: Nike Alpha

The Nike Alpha is Nike's most supportive wireless bra for all cup sizes. Moulded cups provide shaping and the bra can be adjusted at the back, so you can feel comfortably contained. Ventilation on the front and back helps to cool through the heat of your workout. Try out this bra if you wear a size D cup or larger or if you like doing high-impact activity, like running or HIIT, whatever your cup size.

Tips for Getting the Most Out of Your Bra

  • Pick the Right Support Level: if you're a D cup and above, Nike recommends wearing a high-support bra with encapsulation (separate cups). Look for an option with wider and adjustable straps or a racerback style for all exercise intensities. To avoid any unnecessary strain or discomfort, make sure you consider options where you feel contained, but not suffocated. Those with smaller cup sizes may not always require high-support bras, though you might want to look at the level of support, depending on the activity. For lower-impact activities, light support might do the trick, but for higher-impact exercise, like running, a high-support bra will ensure proper coverage.

  • Aim for a Perfect Fit: even wire-free bras can rub and chafe if you don't find the right size. The straps should fit snugly but have room to fit two fingers underneath. The band should fit flat against your ribcage and not dig or ride up. And your breasts shouldn't spill over the sides or front of the bra. If that occurs, consider going up a size.

  • Treat Your Bras with Care: regularly wash your sports bras and try to keep them out of the dryer.

  • Replace Your Bras Regularly: if you notice your bra isn't as supportive as it once was, it's time to shop for a new one.

Frequently Asked Questions

How Many Bras Should I Have?

It's best to wash your bras after a workout or a day of wear. That means if you do laundry twice per week and you wear a bra every day, you should have three to four bras to rotate between.

How Tight Should My Sports Bra Be?

If you can't breathe comfortably, your bra is too tight. You should feel locked in, supported and able to breathe normally and exercise without noticing your bra. To test the fit, try to place two fingers between the underband and your ribcage and then under the straps. If you're able to do this, without feeling loose, you've found your match.
