In anticipation for leggings season (yay!) Emeraldology’s staff and contributing writers scoured the eco-friendly leggings market to see which brands use the most eco-friendly materials. We hope this article helps you find a pair of leggings (or two) that bring comfort to your mind, body and soul!

Nothing beats a good pair of leggings. Well, actually, nothing beats a good pair of sustainable leggings. Synthetic materials like polyester, nylon and acrylic are incredibly harsh on the environment, contributing to fossil fuel extraction and leaving microplastics behind. Even non-organic cotton has a significant environmental impact because of the water, land and chemicals it requires to grow.

So we are putting the spotlight on brands that use eco-friendly materials to make sustainable leggings. Feel free to comment with your favorite brand!

Boody Eco Wear

Leggings Price: $23.95 to $73.95

Sustainable Materials: Viscose bamboo (see process here)

What we love: Great price for sustainable leggings and a variety of bamboo clothes for women, men and babies!

Guest contributor Felicity F. said the packaging was minimal and recyclable (no plastic), sizing was accurate, and the leggings were very comfortable.

“I’m very picky (& cheap!) so to get 10 out of 10 from me is a good recommendation! I don’t wear leggings much, but would definitely order from them again & will look & see what else they have.”

Girlfriend Collective

Leggings Price: $68 to $88

Sustainable Materials: Recycled polyester (RPET) made from recycled water bottles; recycled ECONYL made from recycled fishing nets and nylon; Cupro made from waste left behind by the cotton industry. (See more here)

What we love: Commitment to using recycled materials, catering to all body shapes and supporting social justice issues. See Marie Monson’s full write-up here.

“The design of the leggings appeal to me and they make good running bottoms. Ethical, made with the environment in mind, and fashionable. Although it’s my first experience with this company, I’m overall pretty impressed.”
