Medical-grade silicone
The most common quality choice. It is durable, hygienic, and keeps its shape well over time.
Materials guide
The material affects more than you think
When a menstrual cup feels right, it is not just about shape. The material’s softness, surface, and stability affect comfort, sealing, and how easy the cup is to use. That is why we weigh materials highly in our ranking, and it is one reason why MonthlyCup is ranked number one.
Firmness
Determines how easily the cup opens and how much pressure you may feel during use.
Surface finish
A smooth surface can make cleaning easier and affect how simple the cup feels to insert and remove.
Durability
A good cup should withstand repeated use and cleaning without quickly losing its properties.
Too soft is not always best. Too firm is not best either. Balance is what matters.
Why MonthlyCup scores highly on materials
It is not enough for a product page to say medical-grade silicone. What matters is how the material actually feels in use. MonthlyCup scores highly with us because the feel is balanced: flexible enough for good comfort, yet stable enough for the cup to work smoothly in practice.
That makes a big difference, especially if you want a cup that feels premium without becoming hard to handle.
Which material is best for a menstrual cup?

What does firmness mean in a menstrual cup?
Firmness describes how soft or stable the cup is. It affects both how it opens and how it feels in the body.
Is MonthlyCup made to be comfortable?
Yes, that is one of its biggest strengths in our assessment. It feels balanced rather than extreme in any one direction.
