How can we help?


Period Briefs

Love Luna period briefs are designed to absorb your menstrual flow and can be washed and reused.  Better for you and Muma Earth! They can be worn on their own or as a backup with another sanitary item. This depends on your flow!

Remember to keep a watchful eye over your briefs and change them before their capacity is reached.

With Love Luna period briefs, you can ditch the bulky pads and leave the wings on the runway!

How do they work?

Love Luna briefs feature a super comfy inbuilt pad with four layers of protection.

  1. Soft cotton layer which is closest to your skin for ultimate comfort.
  2. Absorbent padding - breathable layer to catch all those spills.
  3. Waterproof layer - protects your sheets and clothing and prevents awkard accidents.
  4. Sleek microfibre or cotton outer - on the outside depending on your choice of brief.

First time using Lunas?

1. We recommend you try them on a lighter day of your period or when you are at home. This is your ‘experiment’ day when you can learn how your briefs work for you.

2. Remember Luna Lover our Luna period briefs hold different capacities, use that gauge if when you will need to change them if it is less than a day.  Only you know your flow!

3. If you want to change them less often, then wear them with another sanitary item like a menstrual cup or tampon.

4. Now that you’re confident, you can wear your briefs anywhere you like...just not in water!

How do I care for my briefs?

Rinse your Luna briefs with cold water as soon as you can after removal until the water starts to run clear.  Pop them in a washbag, this will help them last longer, with the rest of your washing and wash with like colours on a cold water cycle (max 30 degrees). Then rely on Muma Earth to line dry them.  Did you know sunlight has natural anti-microbial properties that are good for your undies?

Pretty please do NOT:

• Soak (this will ruin their technology)

• Add softener or bleach when washing them

• Tumble dry

• Iron

• Dry clean

How many pairs of period underwear should I buy for each cycle?

This really depends on you and your flow.  If you use them exclusively, we would suggest 7-10 pairs of Luna’s in a single cycle. If you use them with other sanitary products as back-up around 3-5 pairs. 

How do I know if I can use them on their own?

Sadly, we can’t tell you this! Assessing the capacity of the briefs and comparing this with how many sanitary items you use in a day is really important. It’s also important to keep in mind that if your flow changes from day to day, then the way you use your briefs will change, too.

If you think that your flow is nearing the capacity of your briefs (which depends on the style of the brief), then it’s time to change them. We have thousands of Luna lovers successfully wearing our products solo however we also appreciate this may not work for everyone. Therefore, other Luna lovers prefer to wear their Lunas with additional backup, e.g. a menstrual cup or reusable pad, on days 1, 2 and 3 and then go solo for the rest. Some Luna lovers might wear an additional sanitary item for every day of their cycle. It depends on your flow!

Why am I leaking?

It could be due to one or more of the following. Ask yourself these questions:

1.) Have all proper care instructions been followed?
If they're not, then this can damage the technology of the briefs. 

2.) Does your flow exceed the indicated capacity of the briefs?
Full briefs hold 3-4 regular tampons worth of flow which is 15-20 ml. If your flow exceeds this, you might need to use them as a backup, rather than as your primary source of protection.

3.) Is your version of a ‘light’ period more than the capacity of the briefs?
Everyone's version of light, medium and heavy is different. For some people, ‘light’ it is about 1-2 regular tampons of flow, for others it is 3-4 regular tampons throughout the day.  The maximum capacity of our most absorbent period brief is 3-4 regular tampons. You may consider your period to be light, but it may still exceed this capacity.Answer

Do my briefs contain dodgy chemicals

Nope! Love Luna briefs are free of:

  • PFAS (includes PFOS and PFOA)
  • Copper Silver Nanoparticles
  • Copper
  • Silver
  • Nanoparticles
How long will my Love Luna briefs last?

If you follow all care instructions, during and after you use them, they will last between 9-12 months.  Just remember, rinse after use, and wash in cold water only and line dry.  Avoid bleaches, fabric softener and the dryer.

Can I swim in my Love Luna briefs?

Love Luna period and lady leaks briefs are not suitable for swimming.

See our Luna Swimsuit.


Think you can't swim on your period? Think again! Luna Swim is here, designed to protect you from sneaky leaks in and out of the water. Perfect for light periods, bladder leaks, those spotting days in-between or when you're not quite sure your period will arrive. 

How does Luna Swim work?

Four absorbent layers of protection in the gusset work to trap and absorb your period so it does not leak.

Once in the laundry with detergent, the blood is released through the top layer. Reminder: Wash in a cold cycle, no fabric softener and do not tumble dry.

Will I leak once in the water?

The layers in our swim range work to trap and absorb blood while in the water.
We do suggest if you are having a heavy flow day, to use a tampon or Menstrual Cup as a backup.
