BEHIND THE DESIGN

This is our best selling bra. EVER! I designed this bra while I was running marathons. I wanted something stylish but would still look good. I've had so much great feedback and requests for this bra that we've expanded it to many new colors and sizes. I know you will love this bra!

Reviews

Love at first jump

"I’ve avoided HIIT training and jogging for years because I’ve never had the correct support from my sports bras. I’m now exercising regularly because of my Endurance Sports bra! It keeps my chest secure without crushing. It’s comfortable. I will probably size up next time because it’s a little tight on my rib cage. I highly recommend!"

Love it and wear it every day lol

"I love this bra so much and wear it to play volleyball in and I started buying more and wearing it for an every day bra. I have the orange, lightning, coral, white, mint blue, and just bought the black one which is my favorite one so far! I wish they had a periwinkle color, light pink, or tan. It’s medium support. I am 5’9” 195 lbs, athletic build, 36 C and the large fits perfect. I have a couple XL and although they still have support it’s more of a lounge bra, but I still like them a lot. I hope they never stop making these."

Defected

"I have always loved my Endurance Sports Bras and have many colors. However, the white I recently purchased has a defect in the design and does not fit correctly. I would love to speak with some in customer service to have it replaced."

my daughter's favorite

"This is my daughter's favorite bra. I love that the company prioritizes comfort, functionality, and quality."

Rebecca B. (5/5)

Comfortable

"I'm a 34/36 DD so I need more support for running/Hyrox - but love this bra for lifting days, yoga and lounging."

LISA H. (5/5)

Love this bra

"I have upgraded most of my sports bras over the last several years and wear mostly Zyia, but was ready to try something different and this bra is great! I didn’t love having to buy inserts for it. Not speaking for anyone else, but have never loved the nipple showing through look. I paid a high enough price I think they should’ve been included. Otherwise very happy and will likely order more, and get the inserts cheaper on Amazon for bulk."

Carrie H. (4/5)

Inconsistent sizing

"I bought this bra a couple of years ago in an xl, it’s gotten a little snug so I ordered up. Recent reviews told me to size up so I even went to a 3x, I can barely get it on. The sizing is so inconsistent it’s wild. I just went back to wearing the same style, from the same company, in the xl size because it’s significantly better quality and fits better than the larger size."

Weird silloutte

"I wear a size large in all of the swim suits and love them so was excited to try the sports bra. I ordered this in a size large and the back is cute but for the reason the front cuts flat across my boobs and makes them look weird. Like the fabric pulls only in that spot."

Shanna B. (3/5)

Sizing is crazy small

"I've bought several things from Kiava over the years and honestly all of them seem. to run a bit small. I'm a petite person and rarely have trouble finding something that fits anywhere that I shop, even if I have to size up or down one size, but if I have to size up two times for something to be comfortable (in which case then it likely doesn't fit well) then something is wrong. Unfortunately Kiava just must not be made for my body type. Super cute stuff though! And good quality"

Kylene C. (3/5)

Favorite bra

"The endurance bra is absolutely my favorite bra ever. I have it in blue and love it. I purchased it in white in a size Large, same as the blue, and it was TIGHT. So I exchanged for an XL. Still waiting for it but hopefully it fits like the blue. I experienced this before with a white one I lost, but that one fit a little better than the current large I ordered. Not sure how different colors could fit so differently. Well worth the trouble of exchanging."

Q&A

What size do you recommend for 38D bra size?
I would recommend a size XL. We are happy to return or exchange if you find you would like to try a different size!
What size would I buy 34 D/DD
I would recommend a size medium. We are happy to return or exchange if you find you would like to try a different size!
Can this bra be used as a swimsuit top?
This bra is not made with swim material. Although it would probably be fine in a lake, chlorinated water may fade the fabric colors in a pool.
What is the material, Nylon, spandex, cotton? Are bra pads included and if not is there an opening to insert some?
The Endurance Bra is 90% Polyester 10% Spandex. We sell an optional padding set for the Endurance Bra and there is an opening to insert them.
Do any of the bras have molded cups?
We sell an optional padding set for the Endurance Bra. The Asymmetric and Nursing Bras have sewn in foam padding. All of our other bras have removable foam padding.
