Tell me more about the fit:

Our Essential Racerback Bra is meant to fit snugly on the body. To find the correct size, start by fitting the band. Our size chart is based on our field testers' ability to fit two fingers between the body and the band but not more.

To determine the band size:

Measure snugly around your rib-cage, directly under your breasts. Add 3 inches to this measurement. For example, if your rib-cage is 31 inches, your band size is 34. If your result is an odd number, go UP to the next band size. For example, if your rib cage is 32 inches, 32+3=35, round 35 up to a 36 band size.

Our Performance Innerwear is meant to fit snugly on the body. If you prefer a looser fit, we recommend sizing up. If it feels just a little tight and you aren't sure if the next size up would be better, we recommend wearing and washing it a few times to see if it breaks in to your liking before exchanging it for another size.

Will it stretch out?

Our Performance Innerwear will give and relax with a bit with wear and wash. Many women find that it molds to your body over time.

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 Compressive 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.

Favorite running bra

I wasn't sure about a merino sports bra, but I decided to give it a try after being really dissatisfied with how my other sports bras have held up over the years. I'm SO impressed with this bra. I've been marathon training, so obviously lots of high impact running, and this is the only bra I'll wear now. The material is very comfortable and not itchy, the compression is great for high impact, and I can wear it multiple times before washing thanks to the odor resistant wool. And I love that there's no plastic in it. Amazing! I'll be buying more in the future. I got a medium and I'm a 34B for reference.

So comfortable and soft. Supportive! This is a big deal for 32G. I’ll purchase again.

Perfect for winter sports

I coach cross country skiing and spend hours a day out in the cold, alternately going hard and getting sweaty then standing around getting cold. The addition of the merino sports bra has been a game changer, having a base layer that stays warm and dry through it all.
It’s thicker than I thought it would be, and was quite snug to start with (38B and got a large) but after a few wearing it loosens up comfortably while still providing excellent support. I wear it several times between washes and it doesn’t pick up any odor. All the perks of wool with just the right amount of elastic. Thanks for a fantastic product - just got my daughter one too!

Not sure about wool?
