What is the difference between Flex Disc and Softdisc (formerly Instead Softcup)?

Both Flex Disc® and Softdisc® are menstrual discs owned and manufactured by The Flex Co™

Softdisc (formerly Instead Softcup®) is the original disposable menstrual disc and the first menstrual disc to be sold in the United States. It was first introduced to the market as Instead® in 1994 by inventor and triathlete Audrey Contente and garnered a cult following.

In 2016, Flex Founder & CEO Lauren Schulte Wang coined the term “menstrual disc” in order to differentiate the unique shape and benefits of the menstrual disc vs. cup and, soon after, the product adopted its current name—Softdisc. 

Today, Softdisc is carried in retailers across the United States and is sold on Amazon in both the USA and Canada. Learn more about the history of Softdisc,

Meanwhile, Flex Disc was launched in 2016 and became the first premium disposable menstrual disc to feature ComfortSeal™ technology in its rim. This unique blend of medical-grade polymers allows the disc to warm and form to your body, creating a custom fit at the base of the cervix that helps prevent leaks. 

Like Flex Disc, Softdisc is made with medical-grade polymers, but it does not feature the same ComfortSeal™ technology as Flex Disc and is available at a lower price point. 

Both Softdisc and Flex Disc have the same capacity (60 mL, as much as 5+ super tampons) and the same diameter (70 mm). Both products are FDA-registered, hypoallergenic, body-safe, and can be worn for up to 12 hours. 

In 2021, The Flex Co™ added to its Soft line of products with a new menstrual cup, called Softcup®—a new and improved reusable period product designed for a more natural and comfortable fit. The Softcup menstrual cup is now available for purchase on the Flex website as well as on Amazon and in retail stores nationwide.
