Finding a sports bra that feels good against your skin shouldn't be this hard. Most sports bras are made from polyester and spandex blends treated with chemicals like BPA, not what you want pressed against your chest while you sweat. Our organic cotton sports bras are made from 95% GOTS-certified organic cotton with just 5% elastane for stretch. Soft, breathable, and free from harsh chemicals.

4 Reasons to Switch to a Cotton Sports Bra
A 100% cotton sports bra (or as close to it as stretch allows) makes a real difference during your workout. Here's why it matters:
No Harmful Chemicals Against Your Skin: Recent testing by the Center for Environmental Health found BPA at levels up to 40 times California's safe limit in sports bras from major brands. BPA absorbs through skin faster when you sweat. Our organic cotton bras and bralettes skip the synthetics, so there's nothing harmful to absorb.
Breathability That Works With Your Body: Cotton is naturally breathable and moisture-absorbing. For yoga, Pilates, walking, barre, and everyday movement, an organic cotton sports bra keeps air flowing without trapping heat like polyester does.
Gentle on Sensitive Skin: Synthetic sports bras are a common trigger for contact dermatitis, chest acne, and rashes, especially during workouts. Organic cotton is hypoallergenic and free from synthetic dyes, formaldehyde finishes, and chemical coatings that irritate skin.
Better for the Planet: Organic cotton farming uses no synthetic pesticides or fertilizers. When your sports bra eventually wears out, natural fibers break down instead of sitting in a landfill for hundreds of years, releasing microplastics.
What Makes Q for Quinn's Sports Bra Different
Most brands won't make a cotton sports bra because it's harder to produce and costs more than synthetic alternatives. At Q for Quinn, we use GOTS-certified organic cotton because we believe what touches your skin matters, especially when you're active and your pores are open.
Our Organic Racerback Sports Bra is made from 95% organic cotton and 5% elastane. That small amount of stretch is the minimum needed for a supportive fit without relying on polyester or nylon.
Frequently Asked Questions
Is a cotton sports bra supportive enough for running?
Our organic cotton sports bra is designed for low-to-medium impact activities. For high-impact sports like running or HIIT, you may want additional support. Many customers layer it under a lightweight zip-up for extra hold during intense workouts.
Can I also use it as an organic cotton training bra?
Yes. The soft fabric and gentle compression make it a great first sports bra or training bra for teens. It's chemical-free and comfortable for developing bodies that don't need heavy support yet.
What sizes do your cotton sports bras come in?
Our Organic Racerback Sports Bra runs from XS to 3XL, including plus sizes. Check our size guide to find your best fit — the wide band and stretchy fabric accommodate a range of body shapes.
How should I wash my organic cotton sports bra?
Machine wash cold with a mild detergent, then lay flat or hang to dry. Skip the dryer — heat can shrink cotton and break down the elastane over time. Avoid bleach and fabric softeners.
Is the sports bra 100 percent cotton?
It's 95% organic cotton and 5% elastane. That small amount of stretch is necessary for a sports bra to hold its shape and provide support during movement. The cotton is GOTS-certified organic, grown without synthetic pesticides or GMOs.
