Just about anywhere you shop these days, you’re bound to find activewear. Every brand seems to have a line full of items ranging from athleisure pieces that are meant for lounging to performance pieces that stand up to athlete level workouts. Given all these choices, it’s easy to buy a top or a pair of leggings only to realize mid-workout you're a soggy mess—especially during the warm weather that summer brings.

While you might be able to get away with wearing certain leggings or tops for workouts during winter, those items may leave you drenched in sweat in the summer sun.

If you’re looking to beat the heat and humidity with workout gear that’s lightweight and breathable, we combed through the internet to find pieces that will keep you sweat-free and cool, no matter if you’re running outside or taking a Zoom HIIT class indoors. Below are 12 lightweight and breathable activewear pieces, including some of our editors’ tried-and-true favorites.

1. A pair of breezy Lululemon shorts

One of our editor's favorite shorts.

These wildly popular Lululemon shorts have 1,000+ reviews and one of our editors, Courtney Campbell, gushes they are the only shorts she wears to run outside. According to Courtney they are the perfect length and just the right amount of looseness for a “breezier” workout. And happy Lululemon customers also back Courtney up with many saying “the best workout shorts” and “the fit and quality are excellent”. You may want to size up for a roomier fit, as many reviewers commented they sized-up and love the extra room.

This sports bra can double as a crop top.

This sports bra from Nordstrom’s fitness brand Zella has over 4 stars from hundreds of reviews. Perfect for summer, it has a high neck which gives better compression to help keep everything in place while working out. The ventilated mesh panel in front and cutout in back help to keep you cool. You can also choose to wear it alone as a crop top, since it’s cut longer in length than most sports bras.

This bra is the best bra I have EVER owned. It covers everything and keeps them in place.”
