only the best

What we put in our bodies is important. You don't have to make compromises with FLEX. Our products are safe for your body, regulated by the FDA, and made with supreme care and consideration. No chemical bleaches, no toxins, no issues. Only the good stuff.

why it's special

  • Reliable. No more running to the bathroom every few hours - one disc holds as much as 3 super tampons with 60% less waste.
  • Flexible. It was made to fit most people, including mamas & teens to keep you safe from your lightest to heaviest days. And we know what you’re thinking: “This Disc looks HUGE”. It’s actually about the size of a tampon when you squeeze it :)
  • Comfortable. Many of our customers thought having a dreadful period was a fact of life they just have to deal with - until they tried something new. FLEX can’t be felt at all once in place.
  • Safe & Sustainable. 60% fewer cramps and 80% less dryness & irritation compared to traditional period products. Hypoallergenic, not linked to TSS, made of 100% medical grade polymers, FDA approved, cruelty-free, vegan.

you got this

Watch our how-to video here
  1. Insert - Wash your hands, pinch the disc in half and insert it into the vaginal canal by pushing the edge that goes in first down toward the floor. Tuck the rim above your pubic bone.
  2. Wear it for up to 12 hours.
  3. Remove - With clean hands, slide your finger up under the front edge of FLEX Disc and pull straight down, keeping it parallel to the floor.
  4. Dispose- Turn disc upside down to empty in toilet. Place the empty disc in a wrapper and dispose of in the trash.

Are you afraid to try it? We totally get it, trying something new can be challenging but once you nailed it, your period will never be the same. The disc can’t be felt at all once in place. If you need help, our team of amazing FLEXperts are here for you at hello@flexfits.com

Comfortable, effective, and it's true you can have period sex!

I switched from tampons to flex discs probably 6 months ago give or take. I don't even know if I can call it comfortable because I cannot feel it AT ALL ( to the point that my first period trying them I freaked out when I had realized I completelyforgot it was in). I have a pretty heavy flow and I have had no issues with the 12 hour wear. I usually ensure it's popped in place anytime I use the restroom, for the most part it stays where it's meant to while using the restroom. I have also tested the period sex claim, neither my partner or I felt it at all and there was no leakage. I still cannot wrap my head around the semantics for period sex, but hey it all worked out! It is a little messy removal wise but not enough to deter me. I am extremely happy I made the switch. I am no longer constantly worrying about leaks or changing tampons or what the chemicals are doing to my body. If you're on the fence about trying it, just do it! Yes, the cost is a little bit higher than tampons but a box of disc's honestly lasts longer since there is more time between when it has to be changed out, better "absorbancy" and so on and so forth. 100000% recommend.

AMAZING!

I will never use any other product again!! Flex discs have changed my life. I have longer and heavier periods, and these help me save more money, my cramps aren't nearly as bad, and I never have to worry about leaking whether I'm sleeping or hiking. This is the best product I've ever used and I'll never ever go back!!

You’ll forget you’re even on your period!!!!

I absolutely love this product!!! and recommend it to anyone whose comfortable with their body enough to try. I hated the idea of tampons and it wayyyy cleaner and more comfortable than pads or cups! But there’s 100% a huge learning curve. It took me three periods to really get good at using it. The first time I couldn’t get it out and started panicking (the customer service was great though, it totally helped). Sometimes after I put it in, it leaks (although usually it stops after an hour or so, when it settles in I guess?). I would recommend reading other reviews and the tips on the site, and wearing a small pad or period underwear too, just because it does leak a little.

Surprisingly Easy

I've been a Nuvaring user for like a decade now, but for some reason, I was still nervous about trying this.

I finally decided to take it for a spin one night when my period was still winding down but I anticipated getting some action, and WOW - pretty impressed. The mechanics were exactly the same as inserting the NuvaRing and made for blood-free (if a little dry without some handy lube) sex. Taking it out was just as easy for me, although EVERY BODY IS DIFFERENT and if the thought of probing around in your vag freaks you out, it's simply not gonna be a great time for you. I'm giving 4/5 stars because it is inevitably a messy job getting it out... and I'm not thrilled by the thought of another single-use plastic period product but I know flex is making up for that with their other items.

I have not yet tried to go all day using this, but tbh I find it easier to use than the cup and as a device used to hold back the red tide as you get your freak on, I give it a thumbs up!

Also, to all the fuming women writing bad reviews after being reminded of the existence of sex... please return to your convent and find something more productive to do. Thank you.

Never going back to tampons

I started with the flex cup and it’s great, but THEN I tried the free regular flex they sent me. I AM AMAZED. It was soooo easy to put in and I have not noticed it all day! When I pee, it empties. (Wut?!?) I had sex with it in, PERFECT. No leaks, no issues. I am never going back to regular tampons EVER.

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.
