Our wear testers are calling this a new high support favorite. And high support never looked so good - with an elegant design front and back. The chest band includes our signature ribbed elastic, and plush hook and eye closure for adjustability. Wide elastic straps in the back provide an even more custom fit. The straps are padded, to avoid digging in, and the molded cups include perforation for heat release, while holding you securely through any kind of movement, from high impact to low.

Never knew I needed this

As a 34C/D, I have always been in that middle ground where racerback sports bras fit me but were slightly uncomfortable. The small fits my ribs and gives me enough support but is too tight in my shoulders and is too compressive to be comfortable. Medium fits my chest but is too loose in the ribs. Enter the Boom bra. The clasp solves it all. I now have a bra that fits my ribs, provides support and isn't uncomfortable. Thank you Oiselle, I will be buying more.

Third Time's a Charm

This is the third Oiselle bra I have purchased. I started with the Queen, which I liked, but I lost weight and needed to go down a size. I then tried the Sisters Bra. I liked the way it felt and it rarely caused rub burns (marathon miles did cause some issues) but I didn't like the straps showing when I wore a tank top so I decided to try the Boom Bra and I love it so much that I just ordered another. I can't wait until more colors are available.

Super comfy, super awkward shape

Believe everyone who says this is the closest thing to a Juno replacement - it truly is! I've been buying lightly used Junos off Poshmark ever since they were discontinued and this is legit the first bra I've tried in my search for a replacement that I can actually run in. It's also MUCH for comfortable than the Juno, which digs into my armpits.

That said, I've got one major issue with it - I'm a 38D in Oiselle bras and I absolutely despise the shape this bra puts the ladies into. They're high and wide and POINTY in places they've got no business being. Like it's impacting my ability to move my arms around in front of me and changing the fit of my shirts. I feel like Joan Harris from Mad Men. It's a similar shape to the Queen bra, but more dramatic. I reallyreallyreally don't like it and much prefer the minimizing effect of the Juno. Awkward bathroom selfies below for reference, I bet you can guess which is which.

In the end, I will have to be choosey about when to wear this bra depending on what shirt I want to wear, which is a huge, giant, disappointing bummer. It's so gosh dang comfy that even with the limited use case (I'm not often invited to mid-century themed cocktail parties), I'll keep it and use it when I can.

Game Changer

Thought I would never find a bra to replace my discontinued Skirt Sports bras (and before that Juno, but I date myself). Cycling seemed in my future. This hold is good with a little more give, but the sides and overall look is much, much better. Actually cute; its hefty price tag is well worth it! 34dd is my regular size and it works great. A running miracle!
