Period Boxer Shorts for Worry-Free Days and Nights
Heavy days and long nights should not mean waking up to stained sheets. These soft boxer-style period shorts have four layers of leak protection and extra coverage, absorb up to the equivalent of 8 tampons and can be worn for up to 12 hours, so you can sleep and move without checking.


4-layer technology
Four layers of leak protection
Only the absorbent area has the extra layers; the rest is as thin as ordinary underwear. Most women do not notice the thickness while wearing them.
- Comfort layer: soft and breathable against the skin, comfortable all day long.
- Absorbent layer: quick-drying, spreads the flow evenly and helps you feel fresh.
- Moisture barrier: holds everything in so leaks are a thing of the past, and helps neutralise odours.
- Outer layer: waterproof and antibacterial, so you do not get a wet feeling.
