High-Capacity Menstrual Cups for Heavy Flow

Choose your preferred firmness and handle style, then shop the Standard XL options below.

Why Choose a High-Capacity Menstrual Cup?
Heavy-flow days can mean more frequent emptying with a smaller cup. A larger menstrual cup gives you more capacity, which can make long workdays, travel, sleep, and busy schedules easier to manage.
The MeLuna Standard XL combines our largest diameter with our tallest Standard cup body, making it the highest-capacity option in the MeLuna range.
More Capacity
The Standard XL gives you the most capacity available in a MeLuna cup, making it a strong choice for heavier menstrual flow.
Choose Your Firmness
Select Classic for our medium firmness or Sport for a firmer cup that resists compression more strongly.
Choose Your Handle
Pick the handle style you prefer for removal, including Ball, Ring, or Stem options where available.

At 47 mm wide and 56 mm tall, the MeLuna Standard XL is designed for shoppers who want the greatest capacity MeLuna offers. If you already know that a larger Standard-height cup works well for your body, the XL gives you the most room between emptying.
