💸 60-Day Fit Guarantee — Don’t love it? We’ll refund it. 💸
Grabbed these last minute for a friend’s July wedding, lots of dancing. I’m a 34 B, stuck on the bra, pressed it in place, and forgot about it until I peeled it off 8 hours later at 2 a.m. No shifting, no weird lines. Rinsed it in the sink and tossed it in my travel pouch. if I’m dressed, these are coming with me..
Limited stock — Over 12,000 sold this month.Restock not expected until June.
Our Ultra Boost bra is one-size. Results may vary.
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.
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.
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.
