If you’re comparing my mimi vs Hey Zomi, you’re likely looking for a reusable menstrual disc that feels comfortable, stays in place and suits your body.
Both brands are popular Australian-based period care options. Both offer reusable menstrual discs made from medical-grade silicone, and both are designed to collect menstrual flow rather than absorb it.
But there are some important differences when it comes to sizing, capacity, fit, firmness, beginner friendliness and sustainability credentials.
Here’s how they compare.

Award-Winning Sustainable Period Care
A key difference between the two brands is recognition.
my mimi has been awarded Best Sustainable Period Care Solution in Australia in both 2025 and 2026 by the Australian Health & Wellness Awards.
This recognition reflects my mimi’s focus on reusable period care, sustainable alternatives to disposable pads and tampons, and product design that supports comfort, convenience and long-term use.
A single reusable menstrual disc can replace hundreds of disposable period products over its lifespan, helping reduce waste while also saving money over time.
For customers looking for a reusable period product from an Australian-based brand with independent award recognition, this is a strong point of difference for my mimi.
1. Two Sizes vs One Size
One of the biggest differences between my mimi and Hey Zomi is sizing.
my mimi comes in two sizes: Small and Large.
This gives you more flexibility when choosing a menstrual disc that suits your anatomy, flow and comfort preferences.
The my mimi Small is 61 mm in diameter and holds up to 32 mL. It may suit:
- beginners
- people under 30
- those who have not given birth vaginally
- people with a lower cervix
- light to moderate flows
- anyone wanting a smaller, softer-feeling fit
The my mimi Large is 68 mm in diameter and holds up to 61 mL. It may suit:
- heavier flows
- people over 30
- those who have given birth vaginally
- higher cervix positions
- users wanting maximum capacity
Hey Zomi uses a one-size-fits-most design with a 65 mm diameter and 52 mL capacity.
A one-size disc may work well for many people, but it does not offer the same flexibility as choosing between a smaller or larger diameter.
When it comes to menstrual discs, fit matters. A disc that is too small may not stay tucked securely, while a disc that is too large may feel uncomfortable. Having two size options can make it easier to find the right fit for your body.
2. Beginner Friendly Design
Trying a menstrual disc for the first time can feel intimidating, especially if you are switching from pads or tampons.
my mimi is designed with beginners in mind.
The soft silicone body makes the disc comfortable to fold and insert, while the integrated loop tab helps make removal easier. This is especially helpful for first-time users who may feel nervous about reaching and removing a disc.
The two-size range also helps beginners choose a more suitable starting point rather than being limited to one diameter.
Hey Zomi also includes a removal loop and is designed to be soft and comfortable. However, because it comes in one size, users who need a smaller or larger fit may have less flexibility.
For first-time disc users, my mimi’s combination of soft silicone, size choice and loop tab makes it a strong beginner-friendly option.
3. Comfort and Fit
Every body is different.
Your cervix height, pelvic anatomy, flow, age, birth history and personal preference can all influence which menstrual disc feels best.
This is why my mimi’s two-size range is such an important feature.
The Small offers a more compact 61 mm diameter, while the Large offers a wider 68 mm diameter with higher capacity. This makes it easier to choose a disc that better suits your body instead of relying on one standard size.
Hey Zomi’s 65 mm disc sits between the two my mimi sizes. For some users, that may be perfect. For others, it may feel too large or not large enough.
A better-fitting disc can help improve comfort, reduce movement and support more reliable wear.
4. Firmness and Support
Firmness is one of the most important differences between menstrual discs.
A very soft disc can feel comfortable, but some users may find it harder to insert or keep securely positioned. A firmer rim can help the disc tuck behind the pubic bone and stay in place during movement.
my mimi is designed with a soft disc body and a supportive double-edge rim. This gives the disc flexibility while still providing structure.
This balance is especially useful for:
- active lifestyles
- gym workouts
- sport
- walking or running
- swimming
- long days out
- overnight wear
The supportive rim helps the disc stay positioned while the soft body supports comfort.
Hey Zomi is also known as a soft disc. Many users may enjoy that softness, although softer discs can sometimes feel less structured depending on the user’s anatomy and activity level.
If you want a disc that feels soft but still has supportive structure, my mimi has a clear design advantage.
5. Capacity and Heavy Flow Support
Capacity is another key difference.
my mimi Small holds up to 32 mL, while my mimi Large holds up to 61 mL.
Hey Zomi holds up to 52 mL.
For light to moderate flows, the my mimi Small may be enough. For heavier days, overnight use or longer wear, the my mimi Large offers a higher capacity than Hey Zomi.
This makes my mimi particularly flexible because users can choose between a smaller, beginner-friendly size or a larger, higher-capacity size depending on their needs.
6. Active Lifestyle Use
A menstrual disc should fit into your life, not interrupt it.
Whether you are working, exercising, travelling, swimming, sleeping or running errands, you want your disc to stay comfortable and secure.
my mimi’s soft body and supportive double-edge rim are designed to help the disc remain tucked behind the pubic bone during everyday movement. This can be especially helpful for people who are active or who want extra confidence during sport and exercise.
Hey Zomi may also work well for active users, depending on individual fit. However, my mimi’s two-size options and more structured rim design give users more choice when finding a secure fit.
7. Removal
Both my mimi and Hey Zomi include removal aids.
my mimi has an integrated soft loop tab designed to make removal easier and more controlled. This can be especially useful for beginners or anyone who has struggled with discs that do not have a tab.
Hey Zomi has an angled removal loop, also designed to improve accessibility.
Both options are easier to remove than traditional menstrual discs with no grip or tab. However, my mimi’s soft loop tab, combined with its size options, makes it a practical choice for users who want a simpler learning curve.
8. Sustainability
Both reusable menstrual discs can help reduce reliance on disposable pads and tampons.
my mimi is reusable for up to five years with proper care. That means one disc can replace hundreds of single-use period products over time.
This is one of the reasons my mimi has been recognised as Best Sustainable Period Care Solution in Australia by the Australian Health & Wellness Awards in both 2025 and 2026.
For customers who want a reusable period product that supports a lower-waste lifestyle, my mimi offers a strong sustainability story backed by award recognition.
9. Designed and Based in Australia
my mimi is proudly designed and based in Australia.
The brand focuses on creating reusable period products for Australian customers, with sizing, comfort and education at the centre of the product experience.
Hey Zomi is also an Australian-based brand and is manufactured in China.
For shoppers comparing Australian-based reusable menstrual disc brands, both brands are relevant options. However, my mimi stands out for its two-size range, award recognition and beginner-friendly design.
Which Is Better: my mimi or Hey Zomi?
The better menstrual disc depends on your body and preferences.
You may prefer Hey Zomi if you:
- are comfortable with a one-size 65 mm disc
- like a soft disc feel
- want an angled removal loop
- already know that a 65 mm diameter suits your body
You may prefer my mimi if you:
- want two size options
- are new to menstrual discs

Final Verdict
Both my mimi and Hey Zomi offer reusable menstrual discs designed to make periods more comfortable, convenient and sustainable.
However, my mimi offers several key advantages.
With two sizes, a soft beginner-friendly body, supportive double-edge rim, integrated loop tab, high-capacity Large option and recognition as Best Sustainable Period Care Solution in Australia in both 2025 and 2026, my mimi is a strong choice for anyone wanting a more personalised menstrual disc experience.
If you are new to menstrual discs, have struggled with one-size products before, or simply want more flexibility when choosing the right fit, my mimi may be the better option.
