Lily and Fi Adult Menstrual Undies
Everyday comfort. Reliable protection. Confidence you can wear.
Your period is part of life—not something that should keep you from living it. Lily & Fi Adult Period Underwear is thoughtfully designed to provide discreet, reusable protection while supporting good menstrual hygiene and everyday comfort.
Featuring multiple layers of absorbent, leak-resistant fabric, our period underwear helps lock away menstrual fluid while keeping moisture away from your skin. The breathable, soft-touch materials are designed to help you feel dry, comfortable, and secure throughout your day.
Whether you’re heading to work, exercising, sleeping, travelling, or simply relaxing at home, Lily & Fi Period Underwear offers dependable protection without the bulk of traditional disposable products. It’s an ideal choice for light to moderate menstrual flow or as a backup to your menstrual cup on heavier days for added peace of mind.

Part of Our Hygiene & Sanitation Pillar
At Lily & Fi, we believe that menstrual hygiene is about more than managing your period—it’s about supporting your health, comfort, and confidence every day of your cycle.
Our Hygiene & Sanitation Pillar encourages women to choose products and practices that promote cleanliness, reduce unnecessary waste, and make period care simple and effective.
Lily & Fi Adult Period Underwear supports this pillar by offering a reusable menstrual care solution that, when properly washed and cared for, can be worn repeatedly while maintaining comfort and performance. Breathable fabrics help keep you comfortable, while the absorbent layers are designed to manage menstrual flow effectively throughout the day.
Good menstrual hygiene also includes changing or washing menstrual products as recommended, maintaining regular personal hygiene, washing your hands before and after handling reusable products, and following the care instructions provided. Together, these practices help create a healthier, more confident period experience.
How to Use
- Wear your Lily & Fi Period Underwear just as you would your regular underwear.
- Use on its own for light to moderate menstrual flow, or pair with a menstrual cup for extra protection on heavier days.
- Change according to your flow and comfort level.
- After use, rinse in cool water until the water runs clear.
- Machine wash on a gentle cycle with similar colours.
- Air dry to help preserve the fabric’s absorbency and extend the life of the garment.
