Cotton Workout Clothes for Women | Move Naturally by Quinn

Non-toxic activewear is workout clothing made without the harmful chemicals commonly found in conventional athletic wear, including PFAS ("forever chemicals"), BPA, phthalates, formaldehyde finishes, and azo dyes. Most polyester and nylon activewear on the market contains one or more of these chemicals, which absorb through skin faster when you sweat. GOTS-certified organic cotton activewear is one of the cleanest options available because the certification prohibits these chemicals at every stage of production.

For most workouts, yes. Organic cotton is breathable, absorbent, and free from the PFAS, BPA, and microplastic shedding that comes with synthetic activewear. For low-to-medium intensity training, it's a cleaner and more comfortable option. For long-distance running or high-heat cardio, you may want moisture-wicking synthetics as a backup.

Actually, the opposite. Cotton is one of the most breathable natural fibres and helps regulate body temperature by absorbing sweat and letting air circulate. Synthetics trap heat and moisture against the skin, which is why polyester workout clothes often feel hot and clingy after 20 minutes.

Yes. Synthetic fabrics like polyester trap odour-causing bacteria in the fibres, which is why polyester workout clothes can smell even after washing. Cotton releases odour more easily in the wash and doesn't need antimicrobial chemical finishes to stay fresh.

Yes. Organic cotton is one of the most recommended fabrics for pregnancy and postpartum because it's breathable, gentle on stretched or sensitive skin, and free from chemicals that can irritate hormonally-changing skin. Our sports bras and higher-rise pieces work well during and post pregnancy.

Our biker shorts are made with a small percentage of elastane and reinforced stitching to keep them in place during movement. The waistband is wide and doesn't dig in. For the best fit, check the size chart on each product page rather than defaulting to your usual size, as organic cotton fits differently than synthetic activewear.

We work exclusively with GOTS certified facilities, and GOTS explicitly prohibits PFAS, BPA, formaldehyde, and other harmful finishes throughout dyeing and finishing. Where most activewear brands rely on chemical coatings for stretch, water resistance, or performance’, we design around cleaner alternatives.

Yes, and we designed it that way. The apparel and sports bras all work as everyday wear, loungewear, and layering pieces. Cotton doesn't have the plasticky feel that keeps synthetic activewear from crossing over into daily outfits.

Machine wash cold on a gentle cycle with a mild detergent. Tumble dry low or air dry. Skip fabric softeners, as they coat fibres and reduce breathability. Avoid hot water and hot dryers, which can shrink cotton and break down the small amount of elastane over time.

Slight shrinkage is normal after the first wash, especially in 100% cotton pieces, because organic cotton hasn't been chemically treated to prevent it. Our sizing accounts for a small amount of expected shrinkage. To minimize it further, wash cold and air dry when possible.
