7 Sports Bras with Keyhole Cut-Outs for Extra Breathability

Fewer things in life are more frustrating than a swampy underboob—the last thing that should take up space in your mind mid-workout is a sweat stain pooling at the base of your sports bra, or trying to unstick yourself from wet, sweaty fabric.

Luckily, sports bras with keyhole designs are the latest-and-greatest in sports bra design. While brands have made strides in breathability by strategically adding cut-outs and mesh inserts to otherwise swampy places, the keyhole design circulates air right in the middle of things. So bye bye, underboob sweat, and hello, maximum airflow.

1. Nike Indy Yoga Essentials Dri-FIT Sports Bra

Minimalists, Nike’s black sports bra jumps on the keyhole bandwagon without going overboard. This supportive sports bra has two teensy-tiny designs in the front and the back that provide extra ventilation on even the sweatiest days. Other features include adjustable straps, removable cups, and a light lining for extra cushion.

2. Ethos Strappy Cut Out Bra

This pretty sports bra by Ethos takes breathability to the next level. It has a large cut-out on the bra line, right where sweat likes to drip and absorb into the fabric. In addition to the cut-out, it’s also lightweight and strappy for extra ventilation. If you want a bit more support, Ethos also makes a scoop-neck sports bra with a thicker strap that leverages the same simple design.

3. Miss Selfridge Athletic Ribbed Sports Bra

Another minimalist look, this camel sports bra offers just the right amount of peek-a-boo at your chest. For $17, it’s a budget-friendly bra that doesn’t skimp on support. Plus, it’s featherlight, making it a great everyday bralette to wear under tanks and tees.

4. Spanx Workout to Waves Mesh Panel Sports Bra

A sports bra that doubles as a bikini top?! Count me in. Spanx’s ultra-supportive bra is wire-free and lightly lined while still ensuring support during low and medium-impact workouts. Literally go from workout to the waves (or the pool) in this bad boy—the materials are all chlorine- and saltwater-resistant. Just hang dry it after your dip until your next swim (or sweat) sesh.

5. Beyond Yoga Totally Woven Racerback Sports Bra

Beyond Yoga’s merlot-colored sports bra features criss-crossing bands in the center to create a keyhole design. While some elastic bands can be itchy and restrictive, these are woven to be soft and comfortable. It’s machine washable, too, so no shrinking or stretching post-wash.

6. Under Armour Mid-Support Keyhole Bra

Instead of a keyhole design in the front of the bra, Under Armour’s version places the design in the back to circulate air from behind. The racerback straps and extra-stretchy band allow for flexible movement during cardio, circuit training, and yoga. Available in purple, pink, and black.

7. Michi Empress Bra

If you want your sports bra to make a statement, look no further than Michi’s Empress Bra. The vibrant yellow alone is enough to stand out in a sea of black and gray, but the delicate straps and keyhole design make it all the more fashionable. And if yellow isn’t really your color, black, magenta, and a dusty pink are available, too.
