Tell me more about the fit

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?

Not really.  Our Performance Innerwear does give a bit with wear, but instead of becoming loose, it will mold to your body more over time.

For those who need some extra room—the Essential Busty Bra is a low-impact style, designed for C-cup sizes or larger, created with our signature Merino to keep you comfortable and funk-free all day. Best for light activities and everyday wear, our underwire-free, seamless design eliminates digging and rolling, while maximizing mobility. Convertible straps let you wear it straight or modify as a cross-back for additional support. Supportive without being restrictive, our Busty Bra reminds you how comfortable it feels to be in your own skin. If you’re between sizes, we recommend going one size up.

Bonus: Our ZQ, OEKO-TEX 100, and RWS certified Merino is also regenerative and sustainable. (which also means it is BPA free, PFAs Free, and toxic free).

Double Bonus: We hear it all the time… Our Busty Bra really feels like going braless—but with the gentle support you need.

Love these bras!!

Best bra I have found

I am short - 4"11 and and pretty round all over. Need adjustable straps and I HATE wires...also rather busty so the busty bra is perfect for me. I go between the large and the medium sizes and love that they are sustainable, comfortable and breathable!

Bra of my dreams!

I'm a 38G and this bra checks all the boxes! Natural shape, sooo comfy, supportive, stretchy but still hugs nicely. I'm also a nursing momma, and hate nursing bras, this bra works for that too! So 10000% recommend!

The Best!!!

I purchased this bra with high skepticism. I always need high support underwire bra and these kind of bra have been always a no go for me. Well, I was wrong! This bra provides great support!!! For the first time I have been able to go free wire and feel so incredibly comfortable! I will not run with this bra, but I can easily wear it during the day or go for a hike. I can’t imagine how much more comfortable my long road trips or plane trips will be! I am 36 D heavy bust and the medium fits perfectly. To all women having bra issues because of their larger bust, get this one!! I ended up buying two more. They are the best!!!

Comfy but Limited

For reference, I'm a 34C with lower-set ladies, so I need compression and support without sag. I'm going on a trip this summer where we will be one-bagging for several days of walking/hiking, and I was recommended this brand for its temperature regulation and quick drying wool, which is a feature that works well with one-bagging. Some people even said they swim in these, which is something I was hoping I could do, too, since we will be in coastal areas. Following the size guidelines, I got a medium, which is my size in other well-fitting sports bras. It's a comfortable bra, and I may choose to walk in it, but it doesn't give the support I need for most impact activities and doesn't have the right silhouette to wear with tighter workout gear or on its own as a swim top.

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.
