If your menstrual cup works well during everyday activities but leaks, shifts, or loses its seal during exercise, it may be compressing during movement. MeLuna Sport uses our firmest material to help the cup stay open and maintain its seal during running, lifting, climbing, yoga, swimming, martial arts, and other demanding activity.
Firmness is most likely the issue when your cup works during normal daily activity but leaks, shifts, or collapses during more demanding movement.
Your cup leaks mainly during running, lifting, climbing, or intense workouts.
Your cup shifts or loses its seal when you engage your core.
You have strong pelvic floor muscles and have experienced cup compression before.
Your current cup works well on less-active days.
A firmer cup can help when compression causes leaks. If your cup leaks because the diameter is too small, switching to a firmer cup in the same diameter may not solve the problem. Match both diameter and firmness to your body and activity level.
“I originally bought a regular length and firmness, large, as was recommended to me because I've had one child, but it was way too big. I am 5'2" and 105 lbs. I got the shorty firm, Sport, because I am very active with acroyoga, so I am upside down a lot, and rock climbing. It stays in place and I don't even feel it. Highly recommend for the active, petite lady!”

MeLuna Shorty Sport
Our firmest TPE gives MeLuna Sport more resistance to pressure from the pelvic floor and core during demanding movement.
Resists compression during high-impact movement and core engagement.
Helps the cup remain open and supports a consistent seal.
Choose Shorty for a low cervix or Standard for an average cervix. For a high cervix, pair a Standard cup with a Ring Handle and Nupsi extension for added reach.
Choose Small, Medium, Large, or XL based on fit and leak history.
If you tend to experience exercise leaks, emptying and reinserting your cup before a demanding workout can give you a fresh start with placement and seal. Confirm that it is fully open and positioned comfortably before activity.
The firmer material creates a stronger seal and can make folding the cup and breaking the seal for removal more challenging. MeLuna Sport is not recommended for beginners or people with limited finger dexterity or grip strength.
A water-based lubricant can make insertion more comfortable, especially toward the end of your cycle when there may be less natural moisture.
Sport is our firmest option. Classic is more flexible. Choose based on your cup experience, activity, leak history, and how easily you can fold and remove a firmer cup.

| Experience level | Best for experienced cup users | Better starting point for beginners |
These customers describe why the firmer material worked better for them.
“This is the only menstrual cup I've been able to get to work for me. I tried a few silicone ones, but I love the way these are made.”

MeLuna Standard Sport
“I've purchased two of these through the years, they're absolutely perfect. I love that the firmness means I never have to fuss with making sure the cup is open, I just trust that it is. I initially opted for a small, and it was just a smidge too large for my vaginal opening, had to fold to remove, so I've since switched over to the teen cup, which is perfect with that extra firmness.
The ring makes finding the cup easy, and I don't have to mangle my fingernails bringing it out, but make sure you break the suction first, especially if you have an IUD like me.”

MeLuna Standard Sport
Choose cup height based on cervix position. Choose diameter based on fit and leak history. Choose Sport firmness when compression is the problem.
Best for an average cervix and users who have enough internal space for a standard-height cup.
For a high cervix, a Standard cup with a Ring Handle can be paired with a Nupsi extension for added reach during removal.
Best for a low cervix or users who find standard-height cups too long. Shorty offers less capacity because of its reduced height.
Choose the Shorty diameter based on fit and leak history rather than choosing the smallest size automatically.
Some active users choose MeLuna Sport for workouts and the more flexible MeLuna Classic for less-active days or the end of the cycle. Choose the Standard or Shorty Sport that fits your body and the activities you love.
After years of use, the material can become more flexible. If your Sport cup once stayed reliable during workouts but now leaks when you run, lift, or engage your core, it may be time for a fresh Sport cup.
Still working well on regular days? You can keep using it for those days if it is in good condition. Check for tears, cracks, or other signs of wear, and retire any cup that shows them. If leaks have started during everyday activity too, revisit your diameter as your body and fit needs may have changed.
Shop MeLuna SportMeLuna Sport is usually not the best first cup. Its firmer material can be more difficult to fold and creates a stronger seal that can be harder to release during removal. MeLuna Classic is a better starting point for most beginners.
MeLuna Sport can help when leaks are caused by strong pelvic floor or core muscles compressing a more flexible cup. If your current cup leaks because its diameter is too small or it is positioned incorrectly, a firmer cup alone may not solve the problem.
One menstrual cup is often enough. Some customers keep MeLuna Sport as a second cup for active days and use Classic when they prefer easier folding and removal.
You do not need to empty your cup before every workout. If you tend to experience exercise leaks, emptying and reinserting it before a demanding workout can give you a fresh start with placement and seal. Confirm that the cup has opened fully before beginning activity.
Yes. A small amount of water-based lubricant can make insertion easier, especially on lower-flow days. Avoid oil-based lubricants.
Start with the diameter of a cup that already fits well. If your current cup slides down or leaks despite opening fully, you may need a larger diameter. Do not automatically choose a smaller size because you are petite or athletic.
Choose MeLuna Sport when your current cup works during daily life but loses its seal under pressure. Compare Standard and Shorty options or request a personal recommendation before ordering.
