We Found the 10 Best Cooling Bras to Keep You Comfortable on Sweltering Summer Days

Thirdlove is a San Francisco–based bra company that gives women a third option for bras — the assumption being that the existing choices are between sexy and comfortable. We’ll let you decide if they’ve bridged that gap, but we’re more interested in their TempSync fabric, which is specifically designed to regulate your body temperature.

The fabric is infused with natural minerals, which have a cooling effect on your skin, preventing you from breaking a sweat to begin with. If you’re looking for a traditional bra with typical foam cup liners and underwire that’s still designed to keep you cool, this is a great option. The bra is marketed as being “perfect for staying cool through menopausal hot flashes” and comes with typical back closure and adjustable straps. There’s also a wireless option made of the same TempSync fabric, if you prefer.

For the closest thing to wearing nothing at all, Eby puts an impressive level of support into what feels like a mere wisp of fabric. Seamless, nonslip flocking lines all the edges and cups of this completely mesh bra, holding everything in place with as little fabric as possible. There’s no thick band or liners to trap heat, and while the material is made of nylon and elastic, it’s such a small amount of fabric that it’s barely noticeable.

Many reviews from users with larger busts found the bra surprisingly supportive — the larger cup size bras are made with thicker straps and more coverage. But several people, particularly those with larger busts, complained that the material didn’t hold up well and suspected the bra wouldn’t last long. Across the board, most users found the bra to be extremely comfortable, lightweight, and breathable.

Eby also uses a portion of its profits to support women in the developing world with microloans. This mission sounds similar to what its bras offer: a more comfortable life with a moderate level of support.

Fabletics is a subscription-style company started in 2013 by Kate Hudson that quickly became a popular choice for leggings and athletic wear. More than a decade later, the brand is still thriving and has branched out to include a wide array of clothing, including a lingerie line.

Many of its bras, including this one, are available at a deep discount. But the catch is that you need to sign up for the “VIP” membership program, which will auto-charge your card for $70 each month if you don’t log in between the 1st and the 5th and skip the month. You can cancel at any time, but you can’t do this online. You have to actually pick up the phone and call.

If that sounds like more responsibility than a new bra should entail, shopping at full price without a membership is possible — and still a reasonably good deal. This plunge bra is great for low-cut tops as well as providing plenty of airflow on sweltering days. Made entirely of semi-sheer, breathable mesh, the bra features a wonderfully comfortable thin band and an adjustable hook closure in the back.

However, a barely there feel comes with barely there support. This bra is great for lounging, but it doesn’t offer enough support for athletics or a busy day.

SheCurve is a London-based company specializing in lingerie, shapewear, and other innerwear products for plus-size women. The company has incorporated three cooling fabric features into this bra. A mix of breathable mesh is in important places, like the tops of the cups, and cooling fabric is used throughout the body of the bra. We particularly love that the cups are not only unlined but also made of a wicking material that pulls away sweat, keeping you both cool and dry.

The bra’s minimizing effect also makes this a flattering choice for button-up or fitted summer tops. Many reviews rave about how comfortable and supportive this bra is, and several users note the smoothness under shirts. Both across cleavage and from the back, the bra didn’t dig in or cause any bulges. 

This sleep bralette might be the answer to your summertime pajama dilemma. This bralette is made from the company’s NattCool fabric, which is primarily made of eucalyptus fibers.

It sounds like remarkable stuff: According to its Swiss manufacturer, Dagsmejan, it’s 8 times more breathable and dries 3 times faster than cotton. It’s also more environmentally friendly to produce, using 20 times less water and 5 times less farmland to create than cotton.

Because Dagsmejan is a dedicated sleepwear company as opposed to a lingerie retailer, this is the only style of bra it offers. However, there are several other pajama options for women made of the same material, including a slip top, a playsuit, and a kimono.

I’ve never had a product made of Nike’s Dri-FIT technology that I didn’t love. The polyester microfiber material wicks away sweat as well or better than any other product I’ve tried, leaving you comfortable and dry no matter how heavily you’re sweating.

Our tester, Lindsay Modglin, also raved about Dri-FIT’s effectiveness. “I love Nikes Dri-FIT, especially when it comes to sports bras, because I sweat a lot. It wicks sweat and moisture away really well, but the fabric doesn’t cling to my skin or feel sticky,” she says. She describes the bra as “extremely soft, and still feels supportive to my DD bust even though it’s a light-support bra. I typically don’t wear light-support bras because they don’t provide enough support, but this one surprised me.”

As for the fit, she describes the bra as “amazingly comfortable” and “lightweight.”

Cuup’s mesh plunge bra has a deep V-cut, making it a great choice for low-cut tops or for simply maximizing breeze-to-cleavage contact. Cuup’s entire line of bras is designed to have a “minimal look and feel” without sacrificing support. The wireless plunge is no exception. Its entirely mesh cups offer a “barely there” feel, while a single straight line of boning on either side offers a surprising amount of added support and lift, without the under-boob irritation of a standard underwire.

Keep in mind that the fabric is extremely sheer. This is not a safe choice for a white shirt. Added bonus: All of Cuup’s bras are tagless.

I’m usually a baggy T-shirt gym girl, but after starting Pilates, where I found my swampy tees smothering my face and literally choking me in my own sweat, I wanted to ditch every scrap of fabric possible. I’m usually too shy to be comfortable in a crop top, but this one hits perfectly, just brushing the top of a pair of high-rise leggings.

The criss-cross back provides plenty of airflow and is flattering and stylish enough to wear out and about. It’s also much more comfortable than a single-band bra, which, particularly in tops with built-in bras, I tend to find irritating and tight around my rib cage. The design on this one distributes support evenly across your back, removing below-boob pressure without sacrificing support.

The Halara Cropped Yoga Tank Top has held up remarkably well to repeated machine washing — the removable pads haven’t budged, it hasn’t shrunk, and the nylon-elastane fabric hasn’t shown any signs of wear or fading. It’s become one of my most-worn go-to’s.

Stylistically, Tomboyx is a refreshing change for anyone looking for lingerie that’s flattering without being hyperfeminine. This gender-affirming company makes trans-specific underwear for a range of bodies and identities, but much of its line, including this bra, is designed for anyone who prefers a more gender-neutral — yet still slightly sexy — look.

The “peekaboo” cutout offers a reverse take on cleavage while providing a nice breeze where a puddle of boob sweat typically builds up. The material and outline offer a level of comfort that would pair well with boxer briefs with the comfort to match.

As a girl with a long history of cutting the tiny bows off my bras and having more “boy cut” than bikini bottoms in my dresser, I love the look and feel of this bra; it’s simple yet still cute. I did find the elastic band a bit tight, but since my purchase, the website has added a “size up” advisory for this bra. I also appreciate that, unlike most pullover bras, it doesn’t have a racerback, making for less pressure across your shoulders.

While the 95 percent cotton material isn’t ideal for working out (cotton does not wick sweat well), it’s highly breathable, making this a perfect choice for casual wear on hot days. The bra does not include liners, but it does have built-in liner pockets if you’d like to add your own.
