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.

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 gym 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 (Note: The close set racerback style straps are made for action. Prolonged wear might cause skin irritation.)

The result: you stay fresh and funk free even during your most grueling workouts and epic adventures.

Made from naturally sustainable GLDNspun Merino, it's BPA, PFAs, and forever chemical free (unlike, ahem, other bras on the market).

  • 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 Bra is the high-five you need to crush your next PB.

Love all the Branwyn bras

I usually buy the busty essential (natural 32H) in small. After reading some of the reviews for the racer back, I decided on a medium. The fit is great! Got a lot of side boob (I’m used to it by now) but they hold everything in really well. I wore it for indoor cycling, it was surprisingly supportive! Will definitely buy another when I need it.

Mostly love it

I mostly love the Racerback bra although I wish I had bought it in a different color. For whatever reason, I find the black merino blend to be a little tighter fitting and less stretchy (in bra’s and underwear) than the other colors. The first time I wore this bra it was a little itchy, a little tight, and a little too hot. However as I continued to wear it the itch subsided and it grew on me. Even though it’s tight fitting it does not hurt, I can wear it the whole day and it doesn’t hurt. I think I’ll have to keep this for cool weather only as it’s a little too hot for hot weather (Hawai’i). But that is to be expected with the color black and a merino blend. Overall it seems well constructed and like it will last a long time. After wearing it on a few hikes it does not stink. I love the high neck line for performance activities as it feels really supportive.

Want to love as much as the Busty Bralette

Wanted to love this- I got the same size as the Busty Bralette (L) which fit perfect. Felt the Racerback was tighter at the rib cage, but not every where else? Should work well enough for workouts- but I definitely wouldn’t keep it on longer than I need to. I think if I sized up I would lose support elsewhere. Also felt like I spill out under the arms a lot more than the bralette- might just be my body shape, but was hoping for a little bit more coverage there.
Will still keep and use- just not as comfy as I hoped!

Favorite racerback bra!

This is my third essential racerback sports bra, and it certainly won't be my last! It's my go-to, from work meetings to travel days to long runs. It's been really great for winter running, keeping the core warm while still being breathable. It's on the heavier side, but this also makes it feel very supportive. I would recommend sizing up.

Loveee it

This is great! I was looking for some workout gear that wouldn't stink after one use and this fits the bill. No smell at all and I've worn it for my exercises for the last five days. I also live in the tropics and it hasn't felt too hot. As a G cup girly I do need to say it is low impact only!! You could not run in this bra, it doesn't have enough support. But it's great for walking/hikes, pilates, yoga etc. Will def buy again.

MONEY BACK GUARANTEE FOR 14 DAYS

Not sure about wool?

Merino is super soft like cashmere!

We know you'll love it! But just in case you don't, we’ll give you a full refund.
