Size & Fit
Size & Fit
The Black Seamless Racerback Sports Bra runs true to size in a seamless, high-support fit with racerback straps built for running and HIIT. Size up if you're between sizes, since a compressive knit like this fits closer than a standard tee. See our sizing chart for exact Bust and Underbust measurements before you order.
Fabric & Materials
Fabric & Materials
The Black Seamless Racerback Sports Bra is made from a blend of organic cotton and spandex. Organic cotton is grown without synthetic pesticides, unlike conventional cotton, which covers about 2.5% of the world's farmland but accounts for roughly 16% of global insecticide use. The fabric is GOTS certified, verifying organic fiber content and restricting hazardous chemicals, bleaches, and dyes across the entire production process.

Shipping & Returns
We offer standard returns and exchanges on the Black Seamless Racerback Sports Bra: unworn, unwashed items with tags still attached can be returned or exchanged within 30 days of delivery. Email hello@kealoha.co to start a return. Machine wash cold and hang to dry, since high heat is what shortens the life of any stretch fabric fastest.
The Cause Behind This Piece
The Cause Behind This Piece
10% of every Black Seamless Racerback Sports Bra purchase funds ocean conservation. We're still finalizing which specific nonprofit this style will support, and we'll say so directly on this page the moment it's decided, the same way we do for every KeAloha piece. We'd rather tell you what we don't know yet than make something up.
The Black Seamless Racerback Sports Bra is built for the workouts that don't let up — HIIT circuits, sprint intervals, heavy lifting days — delivering high support without relying on the synthetic compression panels that make most performance bras feel stiff. The racerback silhouette keeps straps locked in place through overhead presses and box jumps, and the seamless knit construction means there's no flatlock seam to dig in when you're moving at full effort.
It's knit from a blend of GOTS-certified organic cotton and spandex, formed into one continuous piece rather than stitched from separate panels. Organic cotton skips the synthetic pesticides that conventional cotton farming relies on heavily — a system where cotton uses only about 2.5% of the world's farmland but drives roughly 16% of global insecticide use — so this fabric choice does real work beyond your workout. The spandex supplies the stretch and recovery that create genuine support, while non-toxic, planet-friendly processing keeps the entire bra free of the harsh treatments common in synthetic compression gear.
Hand wash or machine wash cold on a gentle cycle, then hang to dry to preserve elasticity and support over time. And with every KeAloha purchase, 10% funds ocean and wildlife conservation — because pushing your limits and protecting the planet shouldn't be mutually exclusive.
