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.

Sized up for a better fit

Love my busty bralettes in size L, but the L in the sports bra was very snug with not enough coverage for me. Sized up to an XL and the fit is much better. Excellent support with the thicker fabric. Easy to exchange - very happy with this purchase!

Great bra, two caveats.

Really like the compression and the overall quality. Similar other reviews, would much prefer the straps positioned differently and not so close to my neck. The seams have caused a bit of skin irritation around my neck as well.

Girls are snug

I’m 5’4”, 130 pounds, a 36B, and 61 years old. I’m not big and neither are my “girls” but I’m athletic and wanted something that was truly supportive for my activities. I had previously ordered the bralets in a large but I’m in the middle for sizing and went up for everyday comfort. Could I wear a medium… yes. So for the sports bra I ordered a medium to be more compressive and supportive, especially for running. I like my choice! Nice and snug with no bounce. I can easily wear the bra for 3 sweaty runs before I feel it could use a wash. And I mostly just wash all my inner wear in the shower while I’m showering and hang to dry. Super easy and I control how much soap I use, or don’t use, to keep the merino fresh. I’m hoping for a lighter color option so it doesn’t show so much with light colored tops. Best athletic bra I’ve ever owned and I’ve been an athlete my whole life! My suggestion is if you are in the middle for sizing, go up for everyday comfort and size down for the support.

Not the right fit for me

The neck area feels very tight, I wish it sat wider on my chest and shoulders. It’s very narrow on the chest and neck area. Otherwise I do like it but won’t be buying a second one.

Bleeding Racerback

Hello - I just wanted to provide some feedback on my Racerback sports bra. I love it except the black dye bleeds. I wore it backpacking and went river swimming and the dye bled down my back and collected and stained the nude Branwyn underwear that I was wearing. Not a huge deal as I will designate those underwear exclusively to backpacking but wanted to let you know that this happened. Otherwise the products are great.

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.
