Essential Racerback Sports Bra

Our updated Racerback features a new neck and shoulder strap design to offer a more inclusive fit, ensuring unparalleled comfort and freedom of movement.
Built with body hugging, compressive, seamless support for your higher impact adventures, our Essential Racerback Sports Bra is perfect for miles on the trails, laps on the single track, sending your boulder project, or your next HIIT session.
Made to go the distance, the Racerback's heavy-weight 4-way knit, hustles as hard as you. The integrated shoulder strap and racerback design maximizes mobility and movement. Our updated version moves the straps away from your neck and off your traps to fit squarely on your shoulder for maximum comfort.
The result: you stay fully supported, fresh and funk free even during your most grueling workouts and epic adventures.
Made from naturally sustainable Merino, it's BPA, PFAs, and forever chemical free (unlike, ahem, other bras on the market) and featuring our POWRspun knit blend of 76% extra fine Merino, 14% nylon, and 10% elastane, an industry first.
- built with higher compression and heavier material than our Bralette and Busty Bras
-
body-mapped contours provide additional support and separation
- sleeves for removable bra pads (pads not included)
- pullover style with a racerback design for full range of motion
Bonus: Our ZQ, OEKO-TEX 100, and RWS certified Merino is also regenerative and sustainable.
Double Bonus: We hear it all the time… Our Racerback Sports Bra is the high-five you need to crush your next PR.
