The 9 Best Cooling Bras To Keep Sweat At Bay

Sizes: XXS-4X | Fabric: Polyamide, elastane | Colors: 22 | Closure Type: Hook And Eye 

Constructed out of breathable stretch fabric, this underwire-free bralette fits every cup size, from XXS to 4X, and is designed for people who hate wearing bras in summer. With a second-skin feel, it wears like nothing but has a crossover design that holds you in and minimizes bounce, thanks to the supportive elastane.

Pros:

• Available in a wide size range
• Comes in both nude and bold shades

Cons:

• Some reviewers find it runs small, so consider sizing up

Other styles to consider: If this style is sold out, Skim’s Stretch Cotton Triangle Bralette and Cotton Plunge Bralette are great alternatives with similar features.  

Sizes: XS-XL | Fabric: Bamboo viscose, nylon | Colors: 9 | Closure Type: None

The most supportive bras are often the most uncomfortable and expensive. Boody’s ultra-breathable Shaper Bra is a smart alternative. Free of padding, wires, clasps and fasteners, this thermoregulating pick is made from cooling bamboo viscose cloth and features soft ribbing to subtly contour and enhance your bust.

Pros:

• Ethically crafted from organically grown bamboo viscose
• Breathable alternative to cotton that’s great for sensitive skin

Cons:

• Size range only goes up to XL

Other styles to consider: The Breathable Bralette is similarly lightweight while the Padded Shaper offers a bit more coverage.

Sizes: XS-L | Fabric: Lace, nylon, spandex | Colors: 3 | Closure Type: Hook And Eye

With a wireless design and less-structured fit, bralettes are extremely comfortable—especially in summer. Eberjey works with high quality lace and eco-friendly fabrics, which is great if you want a bralette that will last and hold its shape. The Anouk also has adjustable straps and a hook-and-eye closure for a customizable fit.

Pros:

• Lined lace provides coverage under sheer clothing
• Airy, open-weave construction allows for natural ventilation
• Comfortable lace and ribbon-trim detail adds a special touch

Cons:

• On the expensive end
• Size range only goes up to large

Other styles to consider: The Pima Stretch Cotton Bralette and Pima Stretch Cotton V Bralette prioritize comfort with similarly breathable styles.

Sizes: 30A-38H | Fabric: Nylon, spandex | Colors: 16 | Closure Type: Hook And Eye

For those extra sticky days, an all-mesh bra keeps you sweat-free. The sheer material is super breathable, so it won’t hold onto excess moisture, and the deep V silhouette hides nicely under most tops.

Pros:

• Ultra-breathable mesh minimizes sweat and moisture
• Inclusive size range that includes band sizes up to 38 and H cup sizes

Cons:

• Unlined style can be revealing through sheer clothing

Other styles to consider: For more mesh options, we also like the Balconette and Demi bras.

Sizes: XXS-XXL | Fabric: Polyester, elastane | Colors: 6 | Closure Type: None

Sports bras double as tops in hot weather. Vuori’s low-impact Mindset bra is designed for yoga or Pilates as well everyday wear.

Pros:

• Ultra-stretchy fabric contours to your shape
• Quickly wicks away sweat and moisture
• Can be worn for workouts and as a crop top

Cons:

• Offers light support

Other styles to consider: For similarly versatile bras, consider the Yosemite Bra and the Lux Rib Daily Bra. 

Sizes: XXS-XL | Fabric: Polyamide, elastane | Colors: 2 | Closure Type: Hook And Eye

Made with ultra-soft pima cotton and breathable, memory foam cups, this t-shirt-style bra is lightweight and comfortable for all-day wear, even on hot, humid days. The bra comes in a cup sizes A-I, bands 30-48, and various breast shapes (round, slender, asymmetrical, bell-shaped and athletic).

Pros:

• Smooth fit won’t show under t-shirts and light tops
• Cut-out front provides ventilation
• Lightly padded for coverage

Cons

• Expensive

Other styles to consider: The Form Seamless V Neck Wireless Bra and the 24/7 Second Skin Unlined Bra are other size-inclusive, lightweight options.    

Sizes: 32A-42F | Fabric: Nylon, spandex | Colors: 4 | Closure Type: Hook And Eye

Built on comfort and price transparency, Harper Wilde aims to be affordable and extremely comfortable to wear. The Strapless is a standout option—the upper rim of the cups as well as the bands have extra grip to prevent slipping and the X-bridge in between each cup provides extra support with a non-constricting fit.

Pros:

• Comes with removable straps so you can wear this bra multiple ways
• Non-slip grip on the seams
• Breathable fabrication

Cons:

• Limited wear since strapless designs are not meant to be your everyday bras

Other styles to consider: If you prefer the support of straps but still want a lightweight feel, go for the Bliss Triangle or the Luxe Bralette.
