9 Best Sustainable Activewear Brands

We love a good athletic fit. Leggings and a supportive sports bra (or activewear top) are perfect for exercise, weekend errands, and to feel comfortable and cute while WFH. The only problem is, it can be challenging to find quality workout clothes that will outlast squats, sprints, and all the Saturdays (and Sundays) we’re sleeping in.

Fear not, though—our editors have put in the work and put brands to the test. And it’s not just quality we’ve vetted, either. These athletic brands check all the boxes on our wish list—from sustainable materials and manufacturing practices to affordability and inclusive styles and size ranges.

Many of these athletic clothing collections are made with fair trade and ethical labor practices and include natural and recycled fabrics, too. For high-performance activewear that prioritizes your comfort, your workouts, and the planet—look no further. Let us know your faves!

Best For | Size-inclusive activewear (XXS-6XL)

Product Range | Adult activewear, swimwear, outerwear, tops, bottoms, accessories, underwear
Price Range | $28 (tank)–$212 (activewear bundle set)

From skorts to sports bras, Girlfriend Collective has it all. And this thoughtful brand is exceptionally size-inclusive from XXS to 6XL, because every body is an active body. The fabrics are sustainable or recycled, too; for example, its best-selling Compressive Leggings are made with 25 recycled water bottles! From its stance on ethical production to its affordable, gorgeous designs to seeing models who actually look like us, there’s so much to love. Our team especially loves GC’s collection for cute crop tops that actually fit larger cup sizes and hold everything in. (Finally!)

Most pieces are certified Fair Trade, too. With neutral colors and affordable prices, Pact is the perfect place to stock up on all your cotton undergarments, including socks, underwear, and more.

Patagonia is a B Corp committed to the triple bottom line: profit, people, and planet. The brand’s mission incorporates building the best products for those who love the great outdoors while also caring for the environment—that’s why Patagonia also has generous warranties, repairs, and even a secondhand shop. Our team loves (and has used!) Patagonia’s Ironclad guarantee to fix garment holes and stretched-out leggings from years of use—and the process is as simple and sustainable as it sounds! Whether you’re looking for yoga pants, outdoor jackets, running shorts, or activewear for little ones, this California-based brand has got you covered.

Allbirds revolutionized the shoe game when it first launched in 2016.

At the time, the brand only offered adult sneakers—but they became the go-to for anyone prioritizing comfort and sustainability in their daily walks. Since then, this certified B Corp has expanded its product line to include activewear like leggings, shorts, and tees—made with sustainable materials.

For every purchase, tentree plants 10 trees (the company aspires to plant 1 billion by 2030—take that, climate change!), and more than 71 million have been planted already.
