Sustainable clothing brands manufacture apparel using environmentally-friendly materials that reduce the environmental impact of clothing production.
Many companies are also ethically committed to providing fair wages and creating a healthy, safe working environment.
Some people opt for sustainable activewear because they want to have a positive impact on the environment and workers along the supply chain. They enjoy learning where their garments come from and about the production process.
Customers also appreciate timeless pieces that hold up to frequent wear, rather than chasing ever-changing fashion trends. What’s more, people enjoy the uniqueness that small-batch clothing brands provide.

Healthline Nutrition and Fitness Market Editor editor Kelli McGrane tested the Compressive RIB High-Rise Legging and found them to be both stylish and comfortable.
She reported that the fabric is thick enough to conceal underwear lines and provides plenty of stretch for yoga, as well as high intensity interval training (HIIT) moves like skaters and burpees.
One thing to note is McGrane mentioned they run slightly small, so you may want to consider going up a size.
McGrane also tried the Compressive RIB Paloma Bra, which she stated is currently one of her favorite workout tops, as it’s comfortable and surprisingly supportive, even during intense training sessions.
Mate the Label

prAna also supports various charities and donates a portion of select proceeds to Outdoor Reach, a nonprofit that provides meaningful outdoor experiences for kids and teens who may not otherwise have the opportunity to do so.
McGrane tested out a few of prAna’s bestsellers, all of which all fit true to size. She reported that the Everyday Bra holds up on long hikes and during HIIT-style workouts. Plus, it’s comfortable enough to wear under T-shirts and sweaters.
McGrane was also impressed with the Zawn Legging and appreciated the pockets. She noted that the fabric holds up well to washing and is thick enough to hide visible underwear lines.
For a complete outfit, McGrane recommends the matching ultra-soft Zawn Top, which is stylish enough for a morning walk or grabbing brunch with friends after a yoga class.
She found it to be the perfect top layer for a quick morning hike. Plus, she noted, “The gingerbread color, in particular, is stunning and perfect for fall.”
And if you’re an avid hiker or climber, according to McGrane’s husband, the Stretch Zion Pant is the only hiking trousers you’ll ever need. He commented that the pants are lightweight, breathable, and hold up during long days on the trail.

- Brand reputation. Look for a company that offers transparency, supports healthy working conditions, and treats employees well. Some brands also donate a portion of proceeds to charitable causes.
- Materials. Decide whether you prefer natural, semi-synthetic, or recycled synthetic fabrics. If you’re vegan, you’ll want to make sure the brand doesn’t use animal-derived materials.
- Apparel use. Consider what types of activities you want the clothing to suit. Many people choose to wear activewear for everyday use due to its comfort.
- Size and fit. Look for brands that provide a size chart and provide the size and measurements of models. Some companies post customer reviews, which allows you to learn more about how the clothing performs, fits, and holds up over time.
