Stay-Put Promise
Stay-Put Promise
The Bumbas Ultra Boost bra single-sided adhesive is lab-tested for water, sweat, and high-impact motion, so it grips you from yoga flow to pool plunge.
The silicone flexes with every move, eliminating corner lift or shifting.
Pop it on, press for three seconds, and you’re locked in for the day.
Thousands of customers have sprinted, danced, and swum—no slips, just lift.
Find Your Perfect Size
Find Your Perfect Size
Our Ultra Boost bra is one-size. Your lift will vary based on your bra size — check the Lift Chart above to see what to expect.
Sensitive-Skin Friendly
Sensitive-Skin Friendly
We use hypoallergenic, medical-grade silicone approved for daily skin contact—even on ultra-sensitive types.
No latex, no harsh glues, zero itch or redness reported in our wearer trials. Just a secure, gentle hold you’ll forget is there until you peel it off.
Rinse, air-dry, and the adhesive refreshes for tomorrow.
Reusable Up to 50X
Reusable Up to 50X
With a quick rinse in mild soap and an overnight air-dry, Bumbas Boost stays sticky and shape-perfect for at least 50 wears—often more.
Alternating pairs (hello, 2-pack!) lets each set “rest,” extending life even further. More wears = lower cost per lift.
Feels Like Nothing, Lifts Everything
Feels Like Nothing, Lifts Everything
Not a chance of spotting it!
Each bra tapers to under 1 mm at the edge, melting into the cup so there’s no ridge under tees, lace, or silk. Skin-tone shades keep the look seamless in sheer tops and swimwear.
Friends will notice your gorgeous shape, not what’s creating it.
Confidence: on display; Ultra boost bra: your little secret.
Say No to Heat & Odor!
Say No to Heat & Odor!
Silicone doesn’t make you hotter—it simply rests against your skin without trapping extra heat.
Keep cool by wiping off any natural perspiration before placement—our adhesive is engineered to stay locked during sweltering summer walks, HIIT sessions, and pool days alike.
The medical-grade material is naturally odor-neutral, and a rinse after wear keeps it fresh.
Heavy sweater? Lightly dust baby powder under the bust and you’re breezy all day.
