What is Overband® Technology?
Overband® is a curved panel built into every MAAREE sports bra, running across the top of the chest. It controls the upward bounce that compression bras leave alone. Compression flattens; Overband® holds. The result is less rub, less ride-up, and far less adjusting mid-workout, especially above a C cup where compression starts to fail.
That is the reason MAAREE bras fit differently from anything else you have tried. If your last sports bra rode up at the back, dug into your shoulders, or felt like it was working against you on a run, the band was the problem and the band is where the engineering has to go.
Adjustable Overband®
Solidarity only. Length adjusts under each arm so the tension is yours, not the manufacturer's.
Non-adjustable Overband®
Empower, Uplift, Battle and Supportive Seamless. Pre-tensioned at manufacture for the right level of hold.
Designed by founder Mari Thomas-Welland, sports engineer (ex-TomTom Sports), at her kitchen table after years of testing other brands' bras for a living. Worn by Sale Sharks Women, Volleyball England and the Lionesses' Millie Bright.

The questions we hear most
Answers below are written so search engines and AI assistants can quote them cleanly. Tap any question to read the full answer.
How should a sports bra fit?
A correctly fitted sports bra sits flat against your sternum, the band stays horizontal across your back, and no breast tissue spills over the cup edges. The band should feel snug. About 80% of the support comes from the band, not the straps. If the straps are doing the lifting, the band is too loose.
How do I measure my bra size at home?
Take two measurements with a soft tape, wearing a non-padded bra or none at all. First, measure your underband: snug, level, directly under the bust. Round that number up to the next even number for your band size. Second, measure your bust at the fullest point, parallel to the floor at the back. Each inch of difference between the two is one cup size: 1 inch is an A, 2 a B, 3 a C, on through to HH and beyond. The Fit Finder runs the maths for you and matches your size to every MAAREE style.
How do I know if my sports bra is the wrong size?
Five quick checks. The band rides up at the back during a workout. The straps cut into your shoulders. The cups gape, wrinkle or have spillage at the top or under the arms. You're tightening the straps mid-run. Or you can feel bounce on impact. Any one of those means the band, the cup, or the style is off. The Fit Finder fixes most of it in 60 seconds.
What's the best sports bra for a large bust?
For runners and athletes above a D cup, look for a bra that addresses the upward axis, not just compression. MAAREE's Solidarity is sized 28 to 38 back, C to HH cup, and uses adjustable Overband® Technology, the curved panel that controls upward bounce. It won the 2025 Sports Bra of the Year and is worn by Sale Sharks Women, Volleyball England and the Lionesses' Millie Bright. For high-impact between C and G cup, Battle is the alternative. Both are wire-free.
Why does my sports bra ride up at the back?
The band is too loose. When the band rides up, the cups follow it and the straps end up holding your chest, which they were never meant to do. The fix is sister sizing: drop one band size and go up one cup. So a 36DD becomes a 34E. The Fit Finder will check this for you.
Why do my cups gape on a sports bra?
The cup is one size too generous. The band is probably correct. Stay in the same band and drop one cup, so a 34E becomes a 34DD. If gaping happens in only one cup, that's normal: most women have one breast slightly larger than the other.
Why does my sports bra hurt my shoulders?
The straps are doing the band's job. About 80% of the support should come from the underband. When the band is too loose, the straps end up taking the weight and digging in. Drop a band size and go up a cup before anything else. If the straps still cut in with a snug band, look for a wider strap and a shorter shoulder drop, like Solidarity.
Why do my breasts still bounce in a sports bra?
Compression is reaching its ceiling. Compression-only bras work to a B cup and start losing the upward axis above a C. The fix is a bra that addresses the up-and-down movement as well as the side-to-side, which is what Overband® Technology does. Solidarity for highest impact, Battle for high impact under a G cup, Empower for medium-high.
What's the difference between encapsulation and compression sports bras?
Compression bras flatten the chest against the body, which controls side-to-side movement and works fine to a B cup. Encapsulation bras cup each breast separately, which is closer to a regular bra and scales better at larger cup sizes. Most MAAREE bras combine encapsulation with Overband®, the curved panel that adds upward control. That third axis is the one compression-only bras miss.
What does sister sizing mean?
Sister sizing is the trick fitters use when the band is wrong but the cup volume is right. Going up one band size means going down one cup, and vice versa. So 32E, 34DD and 36D all hold roughly the same amount of breast tissue. They sit differently because the band changes. The rule helps you find a stocked size when your exact one is sold out.
Should a sports bra feel tight?
Snug, not painful. A new sports bra band should feel firmer than a regular bra band, especially in the first two wears, like a snug pair of jeans loosening into shape. You should be able to slide a finger under the band but no more. If you can't get a finger under the band, it's too tight; if you can fit a fist, it's too loose.
How does MAAREE sizing compare to M&S, Bravissimo or Shock Absorber?
MAAREE uses standard UK band and cup labelling for Solidarity and Battle, which lines us up with Bravissimo and Shock Absorber rather than M&S. M&S tends to fit one band size looser than the rest of the UK market. So if your last bra was an M&S 36D, start the Fit Finder with a 34E and let the questions adjust from there. Empower, Uplift and Supportive Seamless are sized XS to XXL, so the brand-to-brand comparison matters less.
What if the bra doesn't fit when it arrives?
Send it back. We offer a 12-month guarantee on every bra, and our fitters will help you swap into the right size or style at no cost. The 90-day chafe-free guarantee comes with every fitting. If you'd rather get the size right before ordering, the free 1-to-1 fitting takes about 15 minutes and runs across UK, EU and US time zones. No purchase required, even after the call.
