My new favorite sports bra
After several weeks of looking at this sports bra online, I decided to give it a try, and I’m so glad I did. Since I’d never worn this brand, I relied on the size chart and would say the size chart was accurate. It’s the most comfortable sports bra I’ve ever worn! I’m always looking for sports bras that have non-removable padding and are made for intense, high impact workouts. In addition, I hang this sports bra to dry after washing, and it dries much quicker than most others. Even though this is an expensive sports bra, I consider a comfortable sports bra money well spent.
Fits all my criteria
I hate buying sports bras because they are $$$ and have to be just-so, but my older pairs were worn out and chafing bad. My cup size is small so I usually choose compression-style bras rather that cupped bras. But, my go-to bra isn't made anymore and I needed to try something new. I have now used this On bra for 2 runs: a 7-miler and a 20-miler. This bra was totally comfortable, super easy to get on/off, none of those annoying removable pads, and no chafing seams. I really like the little bit of grippy material on the band that makes it stay put on my ribs and back. I didn't even use anti-chafe with it for either run. The back is mostly open and the arms are cut low so there is no weird pinching and it feels very cool and lightweight to wear. In fact, I immediately bought 2 more after testing it out.
Big boobs rejoice
This is the best sports bra I have ever worn, and I’ve tried a lot of sports bras. No weird bulky zippers or clasps, so the bra looks smooth and cute like lower-support bras do. BUT it’s also super supportive without just compressing my boobs down. 100% worth the price if you have a larger bust and want something supportive and aesthetically pleasing. For context, I’m a 34DD and I got a size medium.
Best sports bra I've ever tried for high-impact
This bra is such a relief. I have probably tried fifty bras for running, and every one of them is a let down. This bra is so soft, comfortable, and supportive. No chafing and it washed well (a sports bra without removable cups for once). I have been nothing but impressed with every On purchase I've made so far, including this bra, shorts, and road running shoes. It is difficult to get on and off, but worth it.
Happy Boobs At Last
I swear I never thought I would pay this much for a sports bra, but I love this thing so much I would gladly buy another one if I could justify it at the moment! After years of being frustrated with other sports bras, this one comes along and changes my life. Saying goodbye to STUPID liners that pop out when you wash them, or scrunch up oddly, has been such a happy experience. Over the years I’ve gotten plenty of sports bras for bustier women that basically suffocated me—binding my boobs as tight as possible is NOT the way to stop them from moving when I’m running. Squashing and flattening a breast into a mono-tit is ALSO not the way to control breasts during a run. THIS. This is the way to do it… this sports bra offers control & support, while still allowing you to breathe and move. Whether I’m doing yoga or on a long run, this is what I’m wearing.
My favorite running bra
Literally the best sports bra ever. Has enough padding for modesty but not heavy or hot. Built in pads means no lost inserts! Looks cute, super comfortable fit.
BEST BRA EVA
I’m a 34D. I do not like to bounce. This bra locks the girls in place while somehow managing to still be comfortable. Best sports bra I’ve ever owned.
Best high-impact sports bra I've ever owned
This bra keeps my sizeable self under control, with no escape during bouncing! I've been through and through high-impact sports bras, and this one is the pinnacle of performance. Also washes well - I wash my bras in the regular clothing load, but I always hang my bras to dry.
Most Supportive Bra!
I really like the firm support my new On Performance Bra gives. It's so nice to know that all the extra chest tissue will stay in one place when I do jumping jacks at the gym or jump down from boulders on a trail.
perfect run bra
First, no removable padding so thanks for that design choice. This bra is perfect for high-impact sports like running and keeps the bounce down without being impossible to get on and off.
