Finding sustainable gym wear that looks cute, hits your quality control requirements (no see-through squat mishaps happening here, please), and is good for the planet is never easy.

While many ethical brands pledge to move mountains for the planet, often the quality, pricing, or size inclusivity just isn't up to scratch. But fear not eco gym queens, for we have compiled a list of our favourite ethical gym wear brands. From sleek yoga pants to figure-sculpting sports bras, running leggings to sweatbands, behold our list of sustainable activewear for every budget - that doesn't cost an arm and a leg. 


Grace Beverley's sustainable activewear brand TALA has been a gamechanger since it landed 2019. With a focus on quality products and totally transparent supply chains, this is eco athleisure at its best. Squat proof, stylish, and inclusive in sizing, everything down to the 100% plantable label is ticking our eco boxes.

Not only are all of TALA's materials sustainably sourced from regenerated waste materials, organic sources or natural fibres, but the brand puts a lot of energy into ensuring their garment workers are paid a fair wage, so you can hit that yoga mat knowing your greener choices are helping keep the planet cool.

tala 365


More than just an activewear brand, we're loving TALA's new 365 collection, a sustainable capsule of luxe everyday basics to take you to and from your next workout. It's created from 95% TENCEL® Modal derived from naturally grown beech wood, with twice the softness of cotton - trust us when we say this material is like butter on your skin. Fully supportive tees are thick enough for those who prefer to go braless (ideal for slow yoga days or your next pilates class), while supple material keeps your peach lookin' peachy in cycling shorts and flares - you'll want to add to basket, stat.
