In today’s health-conscious landscape, many individuals are gravitating toward non-synthetic activewear made from natural materials like cotton, linen, and hemp. This shift is largely driven by concerns over endocrine disruption caused by synthetic fabrics, particularly those containing per- and polyfluoroalkyl substances (PFAS). Initially skeptical, especially as someone who relies on stretchy activewear for daily use, I soon uncovered alarming evidence suggesting that many mainstream activewear brands are heavily laden with these harmful chemicals. After discovering a personal thyroid issue, I committed to sourcing activewear made exclusively from natural fibers.

The Challenge of Natural Fabrics
Finding functional, stylish workout attire made from natural fibers is no easy feat. While I appreciate the comfort of my usual workout ensemble—a sports bra, leggings, and a vintage T-shirt—I was apprehensive about the potential lack of performance and style in natural-fiber options. I feared that I might struggle with discomfort due to the texture of these materials, having grown accustomed to the sleek feel of nylon. However, my mission was clear: to discover high-quality, aesthetically pleasing activewear that would support my sensitive endocrine system.
Los Angeles Apparel: A Cotton Alternative
Los Angeles Apparel, often associated with vibrant nylon pieces, surprisingly offers a diverse range of cotton garments. Their cotton-spandex tank crop top, while not entirely cotton, boasts a 95% cotton composition. At $20, it’s a practical choice for those with larger busts. While the fabric is thinner and may lack substantial support, it’s an excellent summer alternative to traditional bras. The 2×1 Rib women’s tank is another standout, offering a more elegant design that elevates the typical white tank experience.
Baserange: Sustainable and Stylish
Since its inception in 2012, Baserange has focused on creating low-impact, long-lasting garments from natural and recycled fibers. Their transparency regarding materials is commendable. For activewear, Baserange provides several sports bra options, including the cotton rib Heart Bra and the soft bamboo lyocell bra. My top pick is the Oleta high-neck bra, which, despite being predominantly cotton, performs exceptionally well, rivaling even the most popular synthetic sports bras. Additionally, the Baserange Ran Shorts offer an ideal mix of comfort and style for at-home yoga sessions.
OddoBody: Comfort Meets Functionality
OddoBody, known for its cotton underwear, has expanded into a movement line featuring sports bras and bike shorts. I trialed the Shelf Bra and Biker Shorts, initially finding the elastic bands a bit restrictive. However, after wearing them in a hot yoga class, I realized that returning to synthetic materials was no longer an option. Despite the heavy perspiration associated with cotton, I felt liberated, as my body was allowed to sweat naturally without the confines of synthetic fabrics, perfectly aligning with my activewear preferences for comfort and minimalism.
Nu Swim: Organic Swimwear and Activewear
Nu Swim, recognized for its high-quality swimwear, has successfully ventured into the realm of organic activewear. Their Organic-Cotton Sport Bra sets a standard for comfort and breathability, featuring external stitching for added visual appeal. The Organic-Cotton Short Stretch Short is another excellent option, providing structure while maintaining comfort, making it ideal for those who prefer a looser fit.
Merino Wool Wonders: Branwyn
Merino wool has garnered a reputation for its remarkable sweat-wicking and temperature-regulating properties. Branwyn, a brand focused on performance innerwear, utilizes this natural fiber to create high-quality activewear. The Essential Racerback Sports Bra stands out for its supportive and compressive design, making it suitable for high-impact activities. The breathable and quick-drying nature of merino wool ensures comfort during intense workouts.
Sokoi: Embracing the Boho Style
For those looking to break free from conventional activewear, Sokoi offers soft, plant-based clothing that diverges from the standard yoga uniform. The Poppy Scoop-Neck Bra, primarily made from Tencel lyocell, is incredibly comfortable, though it may lack support for high-intensity workouts. Conversely, Sokoi’s Mushroom Cotton Pants strike a balance between comfort and style, providing a flexible, breathable option for various exercises without the tightness of traditional leggings.
H-O-R-S-E: A Personal Touch
Sue Williamson’s H-O-R-S-E brand emerged from her desire to eliminate PFAS from her life following a health scare. The cotton-forward line includes versatile pieces like the navy-blue long shorts and white V-neck shirt, which have replaced my previous athleisure favorites. While slightly thicker than typical workout attire, these pieces are perfect for casual activities like tennis or long walks, offering comfort and a flattering fit that stands apart from mainstream activewear.
Jungmaven: Championing Hemp
Jungmaven has long championed the use of hemp in clothing since the early ’90s. Known for its ability to maintain shape while softening with wear, their Sporty Tank exemplifies this quality. It offers a structured yet flexible fit, making it an excellent alternative to standard activewear tank tops that can feel overly compressive.
Mate the Label: Organic Basics
Mate the Label has built a reputation for organic, non-toxic basics, making their foray into activewear a natural progression. Their leggings, known for being plastic-free, offer exceptional comfort, durability, and fit, making them strong competitors against popular brands like Alos and Lululemon. With their ability to hug the body without constriction, these leggings are perfect for any workout without the worry of endocrine disruption.
In conclusion, the journey to find non-synthetic activewear has revealed an array of stylish and functional options that prioritize health and comfort. By opting for natural materials, we not only support our bodies but also promote a more sustainable fashion industry. The shift away from synthetic fabrics is a worthwhile endeavor, leading to a more mindful approach to our clothing choices.
