A cotton compression sports bra with real support, built in cups that don't move around in the wash, secure enough for running, comfortable enough to forget you're wearing it.

Designed to sculpt, support and move with your body through high intensity training and everyday wear alike, without compromising on comfort.

Made from our breathable OEKO-TEX® certified cotton-rich fabric, it feels firm and supportive on first wear, then softens over time while holding its shape, no plastic-feeling fabric sitting against your skin while you sweat.

Free from harsh chemicals, formaldehyde and pesticides. Because the fabric working hardest against your skin should be the cleanest one you own.

Best for: Running, HIIT, strength training, reformer classes and all-day wear underneath everything.

Performance without the plastic. OEKO-TEX® Standard 100 certified. Easy size exchanges, always.

Fabric

94.2% OEKO-TEX® certified cotton
5.8% elastane (for stretch, support and shape retention)

Crafted from premium cotton designed as a lower-tox alternative to traditional plastic-heavy activewear. Soft, breathable and gentle against the skin, our fabric is free from harsh chemicals, dyes and pesticides, and designed to move comfortably with you throughout the day.

Customer Reviews

Very impressed by this small business, the quality is great and the order came very quickly - in comparison I ordered with Wild Body & found their returns policy very rigid when I ordered something that didn't fit & they didn't have stock of my size and would not offer a refund, will order from Eko again, will not order from Wild Body again.

Cotton Performance Sports Bra

I literally cannot wear any other bra! It’s a proper sports bra and perfect level of compression as someone who lives in sports bras! Will need this bra in other colours please 🤍🤎

Performance Sports Bra

I have worn the sports bra to my yoga classes and it's really comfortable and supportive. Adjustable straps are great and also the support band is really well made and strong! Would highly recommend!

Performance Sports Bra

So incredibly comfy that I could leave it on all day! They are breathable and move well with the body. A real winner for those conscious about the materials they are putting on their body!
