Qualities of an Ethical and Sustainable Activewear Brand

Before we discuss the brands, let’s quickly go over what you should look for in an ethical and sustainable workout clothes brand.

What is sustainable activewear?

  • Natural Fibers

That’s a given! Look for organic cotton, hemp or bamboo mixed with a little bit of recycled synthetic fibers for flexibility. Tencel is also quite a popular choice among ethical activewear brands. So, if you find the names Lyocell or Modal in a shirt or trouser, know that it’s Tencel.

  • Recycled Synthetics

Many eco-friendly sports gear companies are doing an excellent job recycling plastic and using it to make new products. The only thing you need to worry about is the microfibers that eventually break off as you wash your clothes. They can end up in our waterways unless we use specific filters to catch them and dispose off them safely.

  • Eco-Conscious Production

Whether a brand manufactures its products without harming the environment is perhaps the essential factor that makes eco-friendly brands stand out. Green products are produced without using any harmful chemicals, and they either recycle all the waste or dispose it off responsibly.

  • Fair Labor and Transparent Supply Chain

A brand isn’t entirely sustainable until it doesn’t source all of its raw materials from renewable resources. From raw material to the final product, these brands ensure fair trade practices. They provide fair wages and benefits for the workers and take practical steps to keep down their carbon footprint.

  • Charitable Endeavors:

Most sustainable and eco-friendly brands are passionate about uplifting the society. They engage in community work and commit to various charities and nonprofits. They also encourage their consumers to donate for the betterment of the community.

“Sustainable Activewear” is an ever-growing trend, with now hundreds of brands getting on board and each doing their part to tackle the issues of environmental and ethical concern that plague the industry. But is it enough? Franziska Mesche, the founder of Swedish Activewear brand Tripulse, didn’t think so, which is why she set herself the challenge of pushing the possibilities of ethical sportswear further than ever before.

To begin with, though the company was created on the principle of very low carbon emissions. In fact, they’re Climate Neutral Certified, having partnered with Climate Neutral to measure their 2020 carbon footprint and purchase carbon credits to offset this footprint in its entirety.

Then there is the process: They avoid materials that shed harmful microplastics, making use of innovative natural fibers that perform just as well, if not better, and without the associated environmental harm; their material suppliers and their GOTS-certified clothing production factory are based in countries that have fair labor conditions; and their packaging materials not only avoid plastics but are also reusable, recyclable, biodegradable, and kept to a minimum.

Finally, there is their mantra: fitness, sustainability and community. The “life purpose” of Tripulse is three-fold: to better themselves every day in every way, to inspire people to be more active, and to make fitness a driver for positive change.

They’ve also just released their Tencel “Made to Move” shorts. With a unique composition of biodegradable and compostable TENCEL™ and Roica® V550, they are completely microplastic-free.

Iron Roots

When Iron Roots decided to create ethical activewear, they pledged to go 100% plastic-free. Each time we wash polyester clothing, it releases microfibers that end up in oceans and then in our food chain. Sure, oil-based fabrics are silky, stretchy, and sweat-free, but that was exactly the challenge Iron Roots had to tackle! 

To achieve the same feel and performance, the brand uses unusual fabric sources such as natural and organic Hemp and the TENCEL fabric made from Eucalyptus and Beech trees. As a result, you’ll find their activewear almost as soft and sweat-tolerant with another plus; their clothes are antibacterial. 

Moreover, you can return your old apparel to the brand for recycling and get an incredible 15% discount on your next purchase. The company manufactures in GOTS and ISO certified factories that follow fair-trade policies. The brand is also supported by Climate-KIC, a climate-resilient society working for a zero-carbon future.

What to Look For When Choosing Activewear

Buying sustainable products is everyone’s responsibility, but sustainable activewear doesn’t automatically become the most suitable for you. The following are a few of the qualities you should look for in any sportswear clothing product to ensure maximum comfort and productivity.

Woman Exercising

Well, here are some of the few standard yet essential features of eco-friendly sportswear.


Of course, it’s the first thing you should look for in an activewear brand once you’ve ensured its sustainability. Choose the sports bras, leggings, and tank tops that suit your figure and don’t cut into you after some time. So, instead of following any random catalogs, always try out the workout clothes you’re about to purchase.

Moisture Wicking Ability

Fitness hours are sweaty if you’re doing it right. Your activewear must possess excellent wicking ability to ensure an irritation-free fitness session. Sustainable brands usually use natural materials such as cotton or bamboo, which not only maintain your body temperature but also keep you dry and fresh.

Style and Glamor

What’s the use of having so many choices if your gym clothes don’t maintain your style statement? With so many options, you don’t need to sacrifice your glam for abs. Also, if you like yourself in the gym clothes you’ve chosen, you’re more likely to enjoy your fitness session as well.

Activity Suitability

Remember that there are different types of activewear suitable for various physical activities. For instance, if your fitness regime includes cycling, you should steer clear from loose yoga pants. Similarly, a swimming session is impossible to imagine in flowing tops. Hence make choices based on the activity you are about to perform.

Get an Eye for Innovation

These exercise apparel are resistant to microbes and offer a reliable defense against the dangerous UV rays from the sun as well. Look for innovative sustainable activewear that saves you from sun’s UV rays and keeps you germ-free and dry.

Certifications for Sustainable and Ethical Workout Clothes

Man giving thumbs up

In the world of workout apparel, the terms of sustainable and fair fashion can be hard to understand. That’s why we’ve simplified some of the best certifications you should know about before choosing one brand over the other!

Oeko-Tex 100

This third-party certification body confirms the human and ecological safety from harmful chemicals used in textile and leather products. The certificate is issued for 12 months and needs to be renewed periodically.

Global Organic Textile Standard (GOTS)

This internationally recognized standard ensures the 100% organic status of the product. The certification considers the entire production chain from sourcing of raw materials through processing, manufacturing, and delivery.

Fair Trade

Fair Trade monitors the social, economic, and environmental aspects of raw material production. It works to promote fair trading conditions, especially for disadvantaged producers. They issue the certificates once they’re 100 percent sure the buying, selling, and packaging of the product complies with Fairtrade Standards.


Ecocert evaluates organic farming methods and certifies the presence of best agricultural practices for organic raw materials, such as for cotton production. It also certifies compliance with the best environmentally friendly practices and the social requirements level required by the standard.

Worldwide Responsible Accredited Production (WRAP)

WRAP is a social compliance certification that mainly accredits apparel and footwear industries. They issue certificates to the facilities which are free from any forced labor, discrimination, human rights violation, or any unethical practices.


B-Corp measures the entire company’s ethical and environmental policies and not just the products. It ensures a business model that protects the workers, community, buyers, and environment.

Healthy living leads to an active lifestyle. In this fast-fashion era, sustainable activewear brands not only give you a lot of design choices but also provide you with peace of mind while wearing them.

All of the brands listed above are dedicated to producing high-value durable products while maintaining fair trade policies, labor laws, and commitment toward social and ecological endeavors.
