Period Underwear — Your Questions Answered

1. Is period underwear hygienic to wear all day?

Yes. Our multi-layer system locks moisture away from your skin while allowing airflow. You stay dry, fresh, and comfortable for hours.

2. How long can I wear them?

On light to medium days, most women wear them 6–10 hours comfortably. On lighter flow days, they can last all day.

3. Do they replace pads and tampons?

For light to medium flow — yes.

On heavier days, some customers choose to combine them for extra peace of mind.

4. Will they leak?

When worn in the correct size and matched to your flow level, they are designed to prevent leaks during daily activities and overnight wear.

5. Will they feel bulky?

No. They look and feel like regular underwear. The absorbent layer is discreet and invisible under clothes.

6. How do I wash them?

Rinse after use, machine wash cold, air dry.

No fabric softener. No bleach.
