Beat the Heat (and Banish Boob Sweat) With These 8 Cooling Bras

As the name suggests, this ThirdLove bra uses a proprietary material (called 37.5 Tech) that's infused with temperature regulating minerals to keep you cool through hot flashes and heat waves. It also provides plenty of shape without adding heat thanks to the breathable, perforated cups, and there's even a mesh panel for added ventilation between the cups. Other standout features: convertible, adjustable straps, poke-free underwire, and an adjustable back closure for the perfect fit.

This seamless underwire bra from Wacoal offers plenty of support, but ditches stifling, thick padding for full coverage two-ply cups made from moisture-wicking material. Despite the light material, this bra still has sturdy, adjustable camisole-style straps that won't slip and an adjustable back closure to keep you feeling secure.

Designed with activity in mind (think: touristing around on vacay or running errands in the sweltering heat), this pick from Honeylove offers a whole lot of ventilation thanks to mesh paneling in the front and side panels. The moisture-wicking material and silicone-cushioned band help keep things cool and secure, while the internal sling in the wire-free cups provides a shaping lift. It also has adjustable convertible straps and an ajdustable hook-and-eye closure.

I own this bralette and let me tell ya: it feels like wearing nothing. The straps are thin, yet comfortable, and the low V-neck silhouette helps keep things low-profile. But best of all is the material, which is soft, stretchy, and moisture-wicking. It might not be the most supportive pick on this list if you have larger cups, but if you're looking for a solid bralette for lounging or light activity, this one will keep you cool.

Another pick from my own closet, the CoolForm Bra from Outdoor Voices is one of the most breathable sports bras I've worn. It has open back paneling to avoid trapping heat (goodbye, back sweat!) and a sneaky front vent to keep air flowing between your boobs. And, while the material is sweat-wicking and quick-drying, there's also an adjustable back clasp you can undo so you don't have to wrestle your bra off after a hot and sticky workout.

When you think breathable materials, you probably think of mesh. And, when it comes to quality mesh bras, you should think of Negative, the bra and underwear brand that specializes in garments with a next-to-nothing feel. This Sieve Cutout bra is great example of that—it uses super fine Belgian power mircomesh and a dramatic cutout in the front for plenty of airflow between the girls. There are also adjustable straps and an adjustable back closure for a comfortable, secure fit.

If the above mesh option seems like not enough coverage for you, check out this breathable underwire option from Cuup. It uses the brand's 3D Spacer fabric, which provides seamless coverage and shaping without adding any thick padding. The materials are breathable throughout, including the mesh wings on the low-profile band. Plus, you'll be able to adjust the soft straps and back clasp for a perfect fit.

If you've got smaller boobs, you'll want to know about Pepper—the brand makes bras designed specifically for smaller-breasted folks. This wireless scoop bra is one of their more cooling designs thanks to the mesh paneling on the band and a mesh vent between the cups. It also features adjustable straps and an adjustable closure to find your perfect, gap-free fit.
