Any questions?

Is it hygienic?

Yes, our period underwear is hygienic. It features a special antibacterial layer that helps eliminate bacteria and neutralise odours, keeping the underwear clean and fresh throughout wear.

How long can I wear the underwear?

Our underwear can be worn for up to 12 hours, depending on the intensity of your flow. For heavier flows, we recommend choosing our 3-drop protection.

Won't it smell?

No, not at all! Thanks to the special antibacterial layer, any unwanted odours are eliminated, keeping our underwear fresh throughout the day.

Doesn't it feel wet?

No, thanks to our special 4-layer technology, all moisture is absorbed, so it doesn’t feel wet against your skin.

Doesn't the underwear feel bulky?

No, most women don’t notice the thickness while wearing it. Only the absorbent area has extra layers, making that part slightly thicker — but not in an uncomfortable or visible way. The rest of the underwear is just as thin as regular underwear. This means you feel protected against leaks without discomfort, and it remains breathable, unlike pads.

How many pairs do I need?

We recommend one pair for daytime wear and one pair for night-time. A minimum of4 pairs is advised, so you always have clean underwear ready for the next day and enough time to wash the pairs you’ve worn.

How do I choose the right size?

To choose the right size, you can use the size chart above. In general, you can stick to your usual size. Most women find that our underwear fits true to size. If a specific style runs smaller, this is clearly indicated on the product page.

Anna R.

Love the color! Soft and very comfortable product. Works just as expected and gives you piece of mind.

Sally S.

Really comfortable fit and feel confident wearing them. I usually use alongside a menstrual cup, but they have also worked well on their own.

K N.

They are perfect!

CHARLOTTE E.

They are great, comfortable. Easy to wash. I do find on my first day I need to change pairs more even though these are high flow but that is probably just a personal thing to me

Charlotte L.

They are fantastic! I haven’t leaked at all and they are really comfy. They are a little tight but I suppose they need to be to do their job.

Tracy A.

For lighter days. It held up very well. Felt very comfortable on my skin.

Kelly T.

I have been wearing other brands over a few years and have to say very happy I found Luna! They are so soft, comfortable and wash well. They don’t dig in and really hold a heavy flow. I am making the switch now!

Feels good quality, works well, it's surprisingly comfortable and washes well.

I've tried so many other period underwear brands and these are by far the best! I love how absorbent they are so when you've been to the loo, you're not pulling back up into cold, soggy pants!

claire b.

Great for heavy, night time flows. I like the high absorbency because the other brands I’ve tried seem to leak. Also look and design is comfortable and appealing. Amazing pair of period pants.

Mrs J.

Super soft. Great fit. And great absorbency.

Mariia L.

They are amazing! I mainly bought them to wear as I do some sports during the week. I don't like using tampons, prefer pads, but you know, if you do some active exercises sometimes it feels a bit out. These underwear has perfectly solved the problem. I also did try to wear them for the entire day - no leeks, works perfectly if you have a long trip ahead. ✨

Sarah G.

Super soft and comfortable.

Sally K.

They’re so nice, soft and comfortable. They just feel and look like normal underwear. It helps to make me feel like I’m not even on my period.

I can’t recommend these period underwear enough! They are the most comfortable underwear I’ve ever worn during my period. They’re soft, flexible, and let me move freely, even when exercising and all. I feel confident and protected, even on my busiest days.

Jessica W.

This high-waisted absorbent underwear is amazing! It not only provides excellent protection but also gives a nice shaping effect. I feel confident and comfortable. An absolute must-have!

Sarah H.

It honestly doesn’t feel wet at all. I wore the underwear for 10 hours and didn’t even notice.

Plus, I find it much more comfortable than pads.

It honestly doesn’t feel damp at all. I wore the underwear for 10 hours straight, and I didn’t even notice it.

On top of that, I find it much more comfortable than pads.

Vicky W.

I can’t believe I went this long without trying seamless briefs. No leaks, no discomfort, just confidence all day long.

The fit is perfect, and I love how sleek they look. No visible lines, and they do the job flawlessly.
