14 Sustainable Activewear Brands to Work Up A Sweat In

Last Updated: October 12, 2021

Why make working out only good for the mind and body? Include the planet, too, by buying from these sustainable activewear brands!

Finding eco-friendly, socially responsible brands shouldn’t be as hard as it’s made out to be! There are plenty of brands that make sustainability a priority from sourcing materials to ethical work practices.

That’s why we’ve created a list of the best places to check out for your sustainable activewear needs. 

How Are These Brands Sustainable?

The brands on this list source materials with less environmental impact, and even have a beneficial impact by taking plastic out of the ocean and landfills. Materials to look for include recycled polyester aka RPET (made from bottles made of polyethylene), ECONYL® yarn (made from fishing nets and other waste), TENCEL, TENCEL Modal, hemp, organic cotton, and cupro (waste from the cotton industry). 

After reviewing the current industry landscape of activewear, it stands that if a garment has over 78% sustainable material, it is on the upper tier of sustainability regarding materials. This number is especially common in activewear because the other 5-20% is often elastane, nylon, or spandex to achieve the stretchy feel. Hopefully, improvements will come to completely eliminate the use of these plastic fibers for good! 

In the meantime, since some plastics are still found in garments (synthetic fabrics like nylon and polyester, even recycled ones!), place them in a washing bag to prevent microplastics from releasing into the water and ending up in the environment and oceans. For example, check out the Guppyfriend washing bag to place your clothes into when doing laundry. 

Best Sustainable Activewear Brands


Average price range: $25 – $45

Pact is branded as “Earth’s Favorite Clothing Company. The brand pursues this mission by specializing in products made with organic cotton, as well as some hemp products. Pact’s cotton is certified organic by the Global Organic Textile Standard (GOTS). They also produce garments in a Fair Trade Certified Factory. 

Carbon offset shipping is offered to shoppers online, and Pact encourages the customer to reuse the box to donate used clothing. They make this easy by providing a prepaid shipping label to a nonprofit through their Give Back Box initiative.

Indigo Luna is the perfect stop for activewear touting classy, flattering shapes and earthy block colors. They offer tops, leggings, capris, shorts, pants, and flares. 

Indigo Luna has a relatively high percentage of sustainable materials used in their activewear lines. Consider the yoga shorts and tanks made with 92% GOTS certified organic cotton and leggings made from 100% ECONYL (regenerated ocean waste). 

They even sell the GUPPYFRIEND washing bag through their site to wash your synthetic garments (recycled content clothing still releases microplastics).

Although known for their sustainable running shoes, AllBirds also has plenty of fantastic activewear for men and women.

Based in Boulder, Colorado, éclipse was founded in 2002 to simply create clothes that protected skin from sun damage. As the brand has grown, they continually committed to being socially and environmentally responsible, which became an integral focus of their mission. They offer sun protection and high-performance activewear for men, women, and kids

In recognition of their efforts, éclipse was named Best Socially Sustainable Business of 2020.

They also joined Pledge 1% Colorado, and signed the 2020 Circular Fashion Pledge.


Average price range: $95 – $125

“Reprise” means a single repeated action, which represents the brand’s dedication to never using plastic. This stands in opposition to brands who use plastic water bottles (even though recycled), which Reprise argues is detrimental because ultimately this still requires virgin plastic bottles to be used up. Instead, Reprise sources GOTS and Fair Trade certified organic cotton and TENCEL to make clothing. 

An interesting product is their scrunchies, which are made from Fair Trade natural rubber that comes from sustainably-managed forests as proven by the Forest Stewardship Council certification (FSC). 


Average price range: $30 – $100

Even a used pair of their leggings will last years!
