Menstrual Discs: Softdisc™ (formerly Instead Softcup®) vs. FLEX™

What is a menstrual disc?

A menstrual disc is a flat, flexible disc that collects, rather than absorbs, menstrual fluid at the base of the cervix. Unlike menstrual cups and tampons, a menstrual disc does not plug the vaginal canal. This prevents many of the symptoms that may cause discomfort during a woman's period including irritation, dryness, cramping, and bloating. A menstrual disc is also the only internally-worn period product with no link to TSS. To learn more about the many benefits of a menstrual disc, click here.

What options are available for a menstrual disc?

There are currently two menstrual discs on the market, Softdisc™ (formerly Instead Softcup®) and FLEX™. Softdisc™ was first introduced to the market as Instead® and manufactured by EvoFem BioSciences™. The name of the product was changed several times over the years and was most recently called Softcup®. In 2016, when the founders of The Flex Company learned that Instead Softcup® (now Softdisc™) would be discontinued due to price pressure from retailers, they decided to acquire the brand to ensure that more women all over the world could have access to menstrual discs. While the name and ownership of the company has changed, the product has remained the same. Click here to learn more about the history of Softdisc.

Today, Softdisc™ is carried in select retailers and on Amazon while FLEX™ is sold direct-to-consumer as a monthly subscription.

What is the difference between Softdisc™ and FLEX™?

Just as different brands of tampons have different features and fits, so do menstrual discs! While Softdisc™ and FLEX™ share many of the same great benefits, the key difference between the two products has to do with fit and the materials used to make the product. FLEX™ uses ComfortSeal™ technology to create a custom, leak-resistant seal at the base of the cervix. When the FLEX™ disc is inserted, the material of the rim warms and forms to the user’s unique shape, ensuring a perfect fit in 95% of women. A perfect fit means reduced leaks and increased comfort.

Every woman has different preferences when it comes to their body and we empower women to choose whatever option works best for them.

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.
