Long runs are hard enough.
Your tampon shouldn't make them harder.
Traditional tampon designs can allow fluid to travel through straight vertical channels, which may contribute to premature leaks before the tampon reaches capacity. When you're miles away from the nearest restroom, confidence matters.
Sequel's patented spiral technology is designed to promote more even absorption, helping you stay focused on your run.
It's not about running harder.
It's about worrying less.
Designed for movement.
Running, training, racing or simply getting through a busy day all have one thing in common. You deserve a tampon that works with you, not one that distracts you.
Our patented spiral technology helps promote even absorption throughout the tampon, so you can spend less time wondering and more time moving.
Built differently for women who are always moving.
Every mile asks a lot from your body. Here's why Sequel was designed to help you stay focused on your run.

"AS ATHLETES, WE COULDN'T FIND A TAMPON WE COULD RELY ON. SO WE CREATED ONE."
TWO STANFORD ENGINEERS. ONE OVERDUE FIX.
Amanda Calabrese and Greta Meyer weren't looking to start a company. They were athletes — dealing with the same period product failures every woman deals with. A competition in a swimsuit. A lacrosse game in a white skirt. As engineers, they asked a different question: Why hasn't anyone actually fixed this?
Years of R&D, a patent, and an FDA clearance later — Sequel exists. This tampon wasn't rebranded. It was re-engineered.
Sequel was stress tested first by athletes and designed for every range of motion.

FREQUENTLY ASKED QUESTIONS
Have any more questions? Let us know!
Is the applicator hard to use?
The Sequel applicator is compact, which means it needs to extend before insertion — one extra step vs. a traditional applicator. Each box comes with step by step instructions for use, and our team to support if you have any product questions.
Will it actually feel different?
The spiral is designed to promote even absorption, and is designed to be more comfortable. Customers consistently describe it as feeling less noticeable — which is exactly the point.
Is it safe? Are the materials clean?
Yes — FDA 510(k) cleared as a Class 2 medical device, OEKO-TEX Standard 100 certified, and synthetic dye-free. Every component is independently tested.
