The Period Thong You Forget You Are Wearing
A pad can show through tight leggings. This seamless thong has a built-in absorbent layer for light days, or as extra backup with a cup or tampon, and stays invisible under tight clothes. Wash it, wear it again.


Why women switch
Protection without the bulk or the lines
Only the absorbent area has extra layers. That part is slightly thicker, but not in a way you see or feel; the rest is as thin as regular underwear.
The seamless edges and thong cut leave no lines under tight leggings, skirts or trousers, so you can wear what you want on your period.
- Up to 12 hours of wear, depending on your flow.
- Light flow: made for light days, the start or end of your period, or as backup with a cup or tampon.
- Fresh all day: an antibacterial layer helps neutralise odours.
- Washable and reusable: fewer disposable pads and tampons in the bin.
Find your size
Measure your waist and hips, then pick your size
Most women find it true to size, so you can usually stay with your normal size. If you are between two sizes, choose the larger one. The model is 180 cm (5'11") tall and wears size 2XL.

How it works
Four layers, each with its own job
1. Comfort layer
The inner layer is soft and breathable and feels comfortable against your skin all day long.
2. Absorbent layer
A quick-drying layer spreads the flow evenly, so you stay feeling fresh.
3. Moisture barrier
Stops leaks from coming through and helps neutralise odours.
4. Outer layer
Waterproof and antibacterial, so you do not get a wet feeling.

Comfort first
Soft, smooth and made for everyday wear
All moisture is absorbed by the layers, so the thong does not feel wet against your skin. The fabric is smooth and soft, and the seamless finish keeps it comfortable from morning to night.
For a full cycle, plan one pair for daytime and one for the night. Around four pairs is a good start, so you always have a clean pair ready while the others are in the wash.

Care
Easy to wash, ready to wear again
- 1. Rinse: rinse the thong in cold water after wearing.
- 2. Machine wash: put it in a laundry bag and wash at 30°C with a mild detergent.
- 3. Air-dry: hang it to dry. Do not use bleach or fabric softener.
