is a disposable menstrual disc.

FLEX isn't a cup, it's a flexible disc that forms to the shape of your body. The most comfortable period product on the market, it sits at the base of the cervix leaving your vaginal canal free + clear.

7 out of 10 users forget they're on their period while using FLEX.
“It instantly felt more comfortable than a tampon”
12 Hour Wear

Holds 5 tampons worth of fluid. Enjoy your days and nights without interruption. No more worrying about tampon changes during meetings, hikes, yoga, or sleep.

Relieves cramping

Relieves cramping for 7 out of 10 people. Because FLEX sits in the fornix rather than the vaginal canal, it limits the distention in the vagina relieving cramping.

Period Sex? Yes.

Enjoy mess-free + worry-free sex while on your period. Spend more time getting busy and less time cleaning your Egyptian cotton sheets.

Reduces Odor

The DiamondWeave™ construction of FLEX prevents menses from being exposed to oxygen, naturally eliminating period odor without the use of harmful fragrances, chemicals or dyes.

Reduces Leaks

FLEX's ComfortSealTM design comfortably forms to the shape of your body to create a leak-resistant seal.

Lauren said,

"I typically don’t do hikes longer than 12 hours. Before FLEX I was constantly worrying about my period while hiking. FLEX was basically life changing because I didn’t have to worry about changing it."

Megsquats said,

"I found this to be 10x more comfortable than a cup while I was lifting. The flexibility of FLEX makes it so that it’s way more comfortable. I completely switched, I’ll never buy a tampon again. I 100% recommend for any deadlifts..."

Kristin said,

"When you have a light flow, a tampon is really uncomfortable. I thought FLEX was great because it just slides in and out and there’s none of that horrible cotton pull.”

Using is easy.

Unlike tampons and menstrual cups which plug the vaginal canal, FLEX sits just past the vaginal canal and can’t be felt at all once in place.

Inserting FLEX

Slide FLEX into your vaginal canal. Push back and down toward your cervix as far as it will comfortably go (typically the length of your index finger).

Use your finger to tuck the front edge up behind your pubic bone, so it rests diagonally.

Removing FLEX

Hook your finger under the front edge. Pull straight out, keeping your FLEX parallel to the floor.

Place your used FLEX back in its wrapper. Discard in the trash.

Try FLEX with some liners at first.

Sometimes you just feel better with a little backup. FLEX plus liners would be a great combination for you while you transition to FLEX to help guard against leaks until you get the hang of positioning FLEX.
