Inside the Pikini

Soft on Top.
Five Layers Underneath.

Scalloped lace and silky swim fabric on the outside. Five engineered layers on the inside — leak-proof, antibacterial, and rated for up to three tampons' worth.

The kind of tech you'd expect from a medical brand. Hidden in a bikini you'd actually want to wear.

maya k. wearing pikini

i wore my pikini to lake tahoe on day 2 of my period and didn't think about it once. that's literally a first.

i'm 17 and my mom got me these for our hawaii trip. i finally went in the ocean instead of sitting on the towel pretending i was reading.

amara o. wearing pikini

the scalloped trim. the satin ties. it doesn't look like a 'period product' AT ALL. that's the whole thing.

lily p. wearing pikini

i bought one as a backup for my cup on a 4-day cruise. it became my main. zero leaks. wore the same set three days in a row (washed nightly).

hannah w. wearing pikini

my daughter said 'i actually want to wear this' which is the first time she's ever said that about anything period-related. pikini wins.

jess m. wearing pikini

i've tried other period swimwear forever but those options are so basic. pikini is the first period swim that looks like something i'd actually buy.

fit is perfect. ordered my usual bikini size and it was right on. ties are sturdy, not flimsy like cheap swim.

tessa b. wearing pikini

honest review, day 1 of a heavy cycle is still a tampon day for me. but day 2 onward, this is all i wear. exactly what they say it is.

the lining is genuinely thin. i was sceptical it would actually work but it does. swim, rinse, hang dry, repeat.
