Product Details

This isn’t just another sports bra—it’s the result of years of engineering, testing, and breaking the old rules to create something that works with your body, not against it.

Here’s what makes Brilly different:

  • Patented Tri-Balance technology — Personalized support that adapts to your shape
  • Form-fitting construction — High support without the digging or poking
  • Independent strap adjustments — Because your left and right sides aren’t the same
  • Multi-hook closures — Easy on, easy off
  • Breathable, sweat-wicking fabric — Support that works as hard as you do

This might feel like nothing you've worn before—and that's the point.

Size + Fit
  • Size: Brilly is designed to fit true to size. Our patented Tri-BalanceTM construction and form-fitting woven fabric mold to your shape, giving you a more precise fit than typical compression bras.
  • Fit: With independent strap adjustments and a 2.5-inch range of customizable support, you can fine-tune your fit to feel exactly right — whether you're chasing high-impact goals or all-day comfort.
  • Model: Kat is 5'5" and wearing size 34D.

The Brilly Difference:

Most sports bras compress or lift—Brilly does both, with personalized support that moves with your body.

More Comfort

We created support through structure, not just compression to hold you in without squeezing you in.

More Support

Our wrap design and multi-hook closures create 360° hold that stays in place no matter how hard you move.

Less Bulk

Innovative woven fabric construction creates support through structured design rather than layers of thick, stretchy material.

Three Tips for

finding the right fit

Because when it fits, it’s a beautiful thing.

  • 01. Check The Straps

    Do five jumping jacks (or any move you’d normally do in a workout). Too much bounce? Go for a higher-support style, a wider strap or a trusty racerback.

  • 02. Check The Band

    Do five jumping jacks (or any move you’d normally do in a workout). Too much bounce? Go for a higher-support style, a wider strap or a trusty racerback.

  • 03. Check The Support

    Do five jumping jacks (or any move you’d normally do in a workout). Too much bounce? Go for a higher-support style, a wider strap or a trusty racerback.

Engineered with

real bodies in mind

Frequently Asked Questions

What makes Brilly so special?

Brilly isn’t just another sports bra—it’s a complete reinvention of support. While traditional bras rely on outdated design solutions, we engineered the patented Tri-Balance technolgoy that prevents upward movement and adapts to your body, not the other way around.

How do I find my perfect size?

Our bra is designed to adapt, but getting the right size is key. Check out our [size guide] or talk to a fit expert for a personalized recommendation.

Can I wear this all day, not just for workouts?

100%. It’s designed for movement and comfort, so whether you’re crushing a 10k or running errands, Brilly has your back (and front).

What’s the fabric like?

Unlike most high-support bras, we use a woven, four-way stretch fabric that’s lightweight, breathable, and incredibly durable.

What if I’m between sizes?

If you're between sizes, we generally recommend sizing up for more comfort or sizing down for a snugger fit. The adjustable straps and band let you fine-tune your fit.
