Built for High Impact, Not Just Light Movement
Designed with real support features women can feel in the first wear.
For the fuller bust that won’t sit still — and the woman who is done with bras that promise support and still slip, dig, or ride up.
A high-support sports bra for large busts with outside underwire, real band-and-cup sizing, and a racerback fit that keeps the girls in check without the uniboob look. Built for running, HIIT, and all-day wear.
A high-support sports bra for fuller busts that need real containment, not wishful thinking. The full coverage cups and outside underwire help minimize movement during running, HIIT, and intense training, while 1.3-inch shoulder straps, a 2.87-inch wide 4-hook back closure, and a racerback shape spread weight across the band and away from the shoulders. The result is a more comfortable fit that helps reduce post-workout discomfort and keeps your shape separated instead of compressed. Built for women who want support that works in the gym and still feels wearable after.
Is this actually for large busts? Yes. This bra uses real band-and-cup sizing for DD-J cups, so you’re not guessing with S/M/L.
Will the wire dig into my skin? The underwire sits outside the cup fabric, so it does not rest directly against skin the way many bras do.
Is it hard to put on? It fastens in the back with a wide 4-hook closure for a secure fit, then adjusts easily once it’s on.
Does it flatten everything? No — it gives separation and structure without the uniboob look.
What if the size is off? Check the size guide carefully before ordering, especially if you’ve had bad luck with fit in the past.
Can I wear it outside workouts? Yes. It’s made to handle high impact, but many women wear it for everyday support too.
We offer Free Priority Handling on all orders. Please give us 1-2 days for packing and handoff. Typical arrival time: 7-12 days.


If you’ve ever had straps digging in, red grooves on your shoulders, or a band that rolls up the second you move, you know the problem: most bras are not engineered for a fuller bust. This one is. It keeps them in place without the constant chest clutching or the compressed, one-shape look.
S/M/L shortcuts leave too much movement and not enough lift. HSIA uses actual band and cup sizing, outside underwire support, and a wider back closure so the weight moves off your shoulders and onto the band where it belongs. That’s the difference between getting through the day and wanting to take it off by 10 a.m.
Full coverage cups, an outside underwire, wide straps, and a racerback design work together to keep the girls stable without crushing the profile. The fit stays structured, the separation stays visible, and the whole bra feels more secure during runs, jumps, and everyday wear.
Support that still looks snatched
You shouldn’t have to choose between comfort and shape. This bra gives you a secure fit for workouts, errands, and long work-from-home days, while still keeping the profile lifted, separated, and smooth under clothes.
Less bounce during movement
Separation without the uniboob look
Comfort that lasts past the workout
Support that shifts pressure off your shoulders
Designed with real support features women can feel in the first wear.
Most bras for fuller busts either crush the shape or let everything move too much. HSIA gives you real sizing, outside underwire comfort, and support you can actually wear for workouts and daily life.

Yes. It’s designed for DD-J cups with real band-and-cup sizing, full coverage cups, and support features that make sense for larger busts.
No. The wire sits outside the cup fabric, so it’s less likely to irritate skin during wear.
The wide 4-hook back closure is designed for a secure fit, and once it’s on, it stays put without constant adjustment.
Yes. Many women use it for everyday support, long days out, and working from home because it feels stable without looking bulky.
