Here's Why I'm Totally Rethinking This Latest Activewear Trend

We love Girlfriend's activewear pieces because not only are they well-made and comfortable, but they are also made from recycled water bottles. These shorts have 21% spandex and a UPF 45+ rating, meaning they can provide some protection against UV rays.

These are on the shorter side with a 3.5-inch inseam, which makes it perfect for running or any activity where you're going to get hot. They come in a variety of colors, including yellow, green, gray, and even a floral print.

Consider this pair your classic bike shorts. They've got enough stretch with spandex plus ribbed panels.

Best for medium- to high-impact workouts, these shorts are made with recycled nylon, which offers just the right amount of compression. They're also breathable and sweat-wicking.

These shorts have a wide waistband for extra comfort, so you don't have to worry about the fabric digging in. They're mid-rise and mid-length.

If you really want to stand out, you'll have no problem in this lime-green pair. The shorts have a wide waistband and just the right amount of stretch.

You won't feel like you're wearing anything with this lightweight pair—in the best way possible. The shorts are designed for running so they're sweat-wicking, quick-drying, and even have pockets.

Tie-dye is another activewear trend that isn't going away anytime soon. These bike shorts are high-rise and hit just above the knee.

Add a little sparkle to your workout routine with these shorts that have a glitter finish. The fabric has a four-way stretch and is moisture-wicking and antimicrobial. Isn't the lace-up detail pretty cool, too?

The mesh-detail trend first made its way to leggings, and now it's on bike shorts. You can wear these to yoga or studio classes—the fabric is so soft, quick-drying, and breathable. Plus, they have pockets, too.

Things to be thankful for: One of our favorite legging brands, Zella, also makes a pair of bike shorts. These are exactly like the popular Live In High Waist Leggings (with pockets and quick-drying fabric) but in shorts form.

In bright-pink tie-dye, you definitely won't be blending in during your workout. These are made of nylon and spandex, so they're both stretchy and formfitting.

These are designed for training and high-intensity workouts because they're made of Everlux, Lululemon's super-fast drying, breathable fabric. They have side pockets and a hidden waistband pocket, too.

With a unique crossover waistband, these shorts are extra comfortable and easy to move in. They have just enough stretch with 10% lycra.

The fabric on these high-rise bike shorts is super soft yet supportive enough for any kind of workout. Pinhole details on the sides make everything breezy.

With the classic Adidas stripes, these are inspired by '90s street style. The stretchy shorts are great for fitness classes and running errands.
