Boob sweat is one of those annoyances that comes with warm weather. Not only are sweat stains a pain, but moisture sitting on your skin can cause chafing if you're not wearing the right bra.

But the good news is that not all bras are so stifling—some are actually designed to help keep you cool. These cooling bras are typically built with a moisture-wicking fabric that prevents sweat from pooling up with their evaporative designs. Or they will feature a breathable and lightweight material such as bamboo or cotton to promote ventilation. In addition to using strategic fabrics, these types of bras may also have cooling details (such as mesh paneling) along the back and sides or large open backs to encourage breathability.

These are the best cooling bras that will keep you supported and comfortable throughout the day. You'll find everything from structured underwire bras, high-impact sports bras, breezy bralettes, and full-coverage wireless bras that will match your preferences.

The 13 Best Cooling Bras to Buy

Best Overall: Warner's Play It Cool Wire-free Lift Contour Bra

This super-comfortable, wire-free bra has Chill FX cup lining, which helps cool by wicking away moisture. But unlike other wireless bras, this one offers definition with its light lift contouring pads and supportive waistband. This allows it to pair well with a variety of tops, regardless of the occasion. Plus, the convertible straps can easily be fastened into a crisscross design for added support in the back and sides.

"I work outside, and noticed that I didn't get the dreaded 'swamp boob' that normally occurs when wearing a bra in any temp over 70 degrees," shared one shopper. "So, the cool-wicking feature, NOT a gimmick. It actually works."

Best Budget: Hanes X-temp Wirefree Bra

If you're looking for comfort with a budget-friendly price tag, this soft T-shirt bra is the answer. It's wire-free with moisture-wicking fabric and costs less than $12. Even better: Mesh panels help encourage air flow, while its four-way stretch fabric and foam cups flex to fit your unique bust size.

"I love this bra," raved an Amazon shopper. "It's obviously not going to have as much support as a traditional underwire bra, but as someone who is usually a 34D and finds bralettes way too unsupportive, this is a nice happy medium… it also breathes more than normal bras seem to, which is great for summer in Texas."

Best Wireless: Boody Body Ecowear Padded Shaper Bra

Keep things cool with this wireless bra made from bamboo fabric. A sustainable alternative to cotton, it's not only unbelievably soft, but breathable and sweat-wicking too. Additionally, it boasts antibacterial properties, so it won't smell if you start to sweat.

Reviewers were impressed with how much shape the bra offers, noting that its light padding provided the perfect combination of definition and comfort. "The support band doesn't ride up or roll like other bras," reported one customer. "When wet with sweat it doesn't rub or irritate the skin which is the main reason I purchased it. It is easy to put on and take off without having clasps. The cup pads adjust easily for wear after washing. It is light and cool to wear. Texas humidity can be brutal so this is the most comfortable I have found so far."

Best for Small Busts: Maidenform One Fab Fit Demi T-shirt Bra

If you have a smaller cup size and don't need a ton of support, demi-coverage bras are a good choice; plus, the lower cut makes it easier for skin to breathe. This one from Maidenform is a popular pick on Amazon. Available in dozens of colorways, it's made with extra soft fabric and has thin straps and an open back for added breathability.

"This is hands-down the best bra for me, raising and flattering," said one shopper, who noted they typically wore a 30C bra. "I got sucked into trying those incredibly expensive bras advertised on many podcasts just so I could get the 'right size.' I got the right size alright, but those bras were so unflattering for a small chest. Pressed me down. Back to Maidenform it is. I will never stray again."

Best for Large Busts: Glamorise Magic Lift Wire-free Cotton Support Bra

With its Magic Lift band and wide straps, this bra is ideal for those who need a little extra support. Perfect for those with larger bust and cup sizes, it's available in sizes 36B to 56J and is designed with wide, cushioned straps to relieve shoulder strain. And, thanks to a soft cotton blend fabric and well-placed lace cutouts, you'll stay cool and dry while also feeling supported.

"I've looked everywhere for a comfortable bra that offers back support, wide shoulder straps & some type of wicking capability," wrote one Amazon customer. "The Glamourise has it all. I wore it today without pain, gouging, or riding up. This bra has a wide, stretchy band at the base of both cups… no more unpleasant sweating or unwanted rashes, yes! It's extremely lightweight but offers great support. I'm buying six more right away."

Best Everyday Bra: Calvin Klein Modern Cotton Bralette

Free of uncomfortable wires and excessive padding, this lightly lined bralette is made with a breathable cotton blend that's so lightweight, you might just forget you're even wearing it. Those prone to boob sweat will also enjoy its plunging neckline, which helps encourage airflow in between cleavage for more breathability.

"I love these bras so much that I bought two more," shared a fan. "They are perfect for me, with just a tiny bit of push-up and enough padding. They are extremely flattering on me and super comfy."

Best Bralette: Lively the Mesh Trim Bralette

Lace is great, but nothing encourages airflow quite like a full cutout or mesh—and this lounge-worthy pick has both. Its plunged design features a tiny keyhole between the breasts that improves airflow, while the side paneling and lining is made from the brand's signature breathable mesh. The final look offers full coverage that's perfect for wear in steamy temps.

"Excellent foundational garment, it works hard and looks good while doing it," explained one shopper. "This bralette fits well, breathes, and most of all is crazy comfortable." Another shopper added that the mesh "stays dry when I am sweating."

Best Underwire: Cuup the Balconette

Size-inclusive underwear brand Cuup is slowly taking over with its stylish bras made from lightweight, flexible mesh. Although the sheer fabric may seem like an aesthetic choice, it's actually a key part of making a supportive bra that's also comfortable. That's because it allows the skin to breathe and doesn't hold onto sweat like traditional shapewear fabrics.

"It feels almost like a second skin," reported one reviewer. "No poking or digging is happening and my girls are finally supported. Thanks Cuup!"

Best Sports Bra: Yvette High-impact Sports Bras

Designed to get you through the toughest of workouts, this highly supportive sports bra uses an advanced evaporative cool-max fabric and breathable mesh panels so you can break a sweat without any discomfort. Its high-impact structure achieves the perfect balance of support and comfort, minus any feeling of squeezing, pinching, or restrictiveness. Its criss-cross back straps give you a sense of extra security and lift. And, the bra is available in sizes small to 5XL.

"I can hardly ever find a bra, let alone a sports bra, that gives me both comfort and support," explained one Amazon shopper. "This sports bra does both. Its good for workouts and also hooks like a bra which I can wear under my tops as well."

Best With Back Support: Playtex 18-Hour Cooling Comfort Wire-free Bra

If back support is your top search criteria in a bra, this wire-free bra from Playtex has everything you need. Not only is it a fan-favorite for its cooling ventilating design but also for its wide, stabilizing back, which keeps everything in place and smooth while minimizing the chances of your bra rolling up. It also has a four-way stretch to it as well as adjustable clasps in the band for a customized and comfortable fit.

"This bra provides fantastic support and there are no wires," said one reviewer. "It is so comfortable, there is no area on the bra that rubs or irritates the skin. The bra keeps you cool, especially along the bottom band. It does not slip up in the back. This is the best bra I have ever worn."

Best With Side Support: True & Co True Body Lift Mesh Scoop Neck Convertible Bra

Those looking for side support from their cups will enjoy the supportive fit of the True & Co True Body Lift Mesh Scoop Neck Convertible Bra, which combines the coverage of a sports bra with the comfort of a bralette. Made from a soft-to-the-touch fabric that's optimized with breathable mesh panels, this seamless pick easily pulls over and is designed to prevent any slippage with its structured bust.

"I was dubious at first that this would feel like anything other than a sports bra," admitted one customer. "But the fabric is so incredibly soft and there is no elastic to dig in and cause discomfort. This bra is lightweight, supportive, and comfy enough to wear day or night."

Best Full-coverage: Just My Size Pure Comfort Seamless Wire-free Bra

This silk-like seamless bra offers a flexible fit courtesy of its wire-free design. This also provides a more full-coverage feel with its wide straps and fuller back for those that prefer a more supportive and secure fit. But it does so without compromising structure thanks to its slight under-bust shaping. To keep you cool, the bra utilizes moisture-wicking technology and is lightweight to prevent overheating.

"I was looking for a comfortable bra to sleep in or wear to lounge around and this bra is perfect," wrote one shopper. "No pinching anywhere. Super soft. Super comfortable. Easy to slip on overhead like a T-shirt or to step into and pull up. Keeps the girls comfortably in place while sleeping but supportive enough to wear while running errands."

Best With Front Closure: Fruit of the Loom Front Closure Cotton Bra

Created with front closure fans in mind, this affordable bra, which can be worn as a low-impact sports bra or a supportive bralette, is made with breathable cotton that is equal parts soft and stretchy for a comfortable fit. The ruched detailing and scoop neckline adds a stylish touch to this full-coverage pick.

"This bra is the best of both worlds," raved one five-star reviewer. "It has the comfort of soft cotton without wires, but offers seven traditional hook-and-eye catches in the front for ultra support and shaping…This one is easy on, easy off and is great for working out. It's also flattering."

From sports bras to bralettes, there are many different types of cooling-bras that will give you the breathability and comfort you need to fight the sweat.
