The summer is almost here and as temperatures start to rise, I worry about what I'm going to wear in the coming heat. I'm always on the move, I sweat a lot, and I need pieces that are comfortable. That's why I'm so excited about Old Navy's 50% off sale on activewear bottoms – including shorts, leggings, jumpsuits, skorts, tennis dresses, joggers, and more. But, it's for today only, so do not hesitate. 

There are so many colors and styles to choose from, and there's still an ample amount of sizing from X-Small to 4X-Large. Plus, since they're activewear, the pieces are breathable, stretchy, and moisture-wicking to keep you cool when it starts to get hot. But don't think they're just for working out, there are jumpsuits, tennis dresses, leggings, and more, that you can wear for errands, brunch, and more.

But, since the sale is only today, I'll stop talking. Get over to Old Navy and start loading your cart with the bottoms you'll be wearing every day this summer. Go!

Bike shorts for just $12? And they come in 10 colors? I'm buying 3 pairs. Stretchy and smooth, these shorts are perfect for working out, wearing under dresses, or just walking the dog. There's even a hidden back pocket.

These sleek ankle pants are stretchy, breathable, moisture-wicking, and can pull off a polished look if you were heading into the office. Snag them in 4 neutral colorways, that also go with everything, and you're all set.

With a vintage feel and a 3.5-inch inseam, these soft fleece shorts are so comfy and flattering (according to reviewers). One enthusiastic shopper reported, "perfect shorts for curvy girls for the hot girl walks."

Full of flounce and flirt, this Old Navy skort is as cute as it is comfortable. There's plenty of spandex for stretch, a 3-inch inseam on the biker shorts, and a pocket for your phone. Snag it in 5 colors for just $18.

Available in 13 colors, these buttery soft leggings will immediately move the top of your rotation this summer. They have side pockets, they're moisture-wicking, and reviewers note that they stay secure around your waist (even when you're doing Crossfit).

Serve up the latest tenniscore trend with this square-neck athletic dress. It's great for on and off the courts, and there's a built-in bodysuit (with shorts) so you can feel chic and confident when you're on the move. And many reviewers report that you can wear this without a bra.

Old Navy powersuits are tailor made for the summer. They're breathable, sweat-wicking, and you can layer them with a crop top, oversized button down, and more -- or just wear solo. There's even a built-in shelf bra if you want to go braless.

Made of lightweight nylon, these cargo joggers are something you can wear every day in the heat. Plus, the colors and texture elevate them above your traditional joggers. They're easy to style and so, so comfy.

Your new go-to shorts have arrived. They have built-in briefs for coverage, a 3-inch inseam, and come in 7 cute colors. Light and breathable, they're just what you need on sweaty days, plus there's a zipper pocket for cash, cards, or keys. 

Like to stay on-trend? Then you have to add these flared pants to your cart. They're sweat-wicking with a cross-front waistband, and one reviewer added, "Not sheer or uncomfortable after hours of wear at work or around town, smooths and lifts without being EXTRA."

Whether you layer this bodysuit with a cute jacket or button up, or wear it solo, you'll get some compliments. With a scoop neck and deep scoop back, the soft, stretchy material will fit you like a glove. Snag it in light blue, navy, brown, or black.
