Editor-Tested: The Best Sports Bras for Big Busts

Touted as Nike's "highest support bra yet," the Pro Rival definitely lived up to its claim. I wore it to a high-intensity interval training class, where I participated in weighted jumping jacks, mountain climbers, squats, and more, and I can honestly say I did not think about my chest once during the workout. The one big downside of this bra was the difficulty of putting it on and taking it off. But once it was on, it was secure. It kept my boobs separated (which is great because sometimes bras have the tendency to squeeze so tightly that I get a uniboob), and it was comfortable.

The best part of any Under Armour product is the sweat-wicking technology, and this bra was no different. The UA Armour High offered more coverage than some of the other bras I tried, which had its pros and cons. While I appreciated zero side-boob spillage, there was too much fabric underneath my arms, which resulted in some unwanted friction. As far as bounce goes, my chest was firmly in place throughout the spin class, which is always the most important concern.

While this bra seems a bit complicated on the outset, I was pleasantly surprised. Underneath the front-zip closure are structured cups that clip together for a comfortable, yet supported fit. I have two Victoria's Secret sports bras already and I sometimes struggle clasping it together quickly, but this version was simple. I wore the Knockout to a spin class, and I had no issues. My one complaint was that the top layer bagged a bit, but other than that, this one was a winner.

Can a sports bra be cozy? After wearing Champion's Spot Comfort bra, I'd say yes. The design is a hybrid between your go-to T-shirt bra and a sports bra, which means that putting it on is intuitive—a big plus. The thick strap at the bottom wasn't too constricting either, but it still provided moderate support. I wore it to a cardio class, and it fared well, but wasn't as supportive as some of the others. Though, it was easily the most comfortable.

If you want to make a fashion-forward statement with a sports bra, this is the one for you. However, while it's cute, it offered the least amount of support, and it while it would not hold up in a boot camp class, it would work for yoga or barre. The cut along the sides allowed for more exposed skin, which in my case meant that I had a little bit of spillover. Another downside is that the adjustable straps only go so far, so I was unable to adjust it for the right fit.

Definitely the most traditional sports bra I tried out of the bunch—the Gap version fits much like you'd expect. With its simple pullover design, it offers no padding or any other frills, though that's not necessarily a bad thing. What sets it apart from the many sports bras you probably already own is the thick elastic strap. The larger band kept the bra in place, plus it gave the style a retro feel that I enjoyed.
