Even better, pair it with our pads or liners for that 150% no-leak backup. Or wear it everyday and skip the liner.

Our Sustainable Story

Bamboo is a naturally renewable grass requiring very little maintenance to farm. This highly sustainable plant does not require pesticides or herbicides to grow, and its anti-bacterial and hypoallergenic properties make it a perfect match for delicate skin. 

REFINED bamboo is handpicked from sustainable FSC-certified plantations, ensuring water use it kept to a minimum, and resources are renewable and earth-friendly.
Blessed with natural insect repelling properties, bamboo yields less crop wastage than organic cotton.

The best part for your body: bamboo is entirely vegan and cruelty-free, without any fragrances, chlorine, artificial antibacterial agents or GMO — just natural, sustainable support.


How do I know what size to get?

Our period underwear comes in 5 sizes. Pick the right size by referring to our sizing chart here

How do I care for my period underwear?

Rinse your period underwear each time after use until the water runs clear. You may hand wash it with cold water or put it in the washer. If you are using a washer, put it in a lingerie bag, use the gentle/delicate cycle and wash below 30°C. Then, hang dry. Do not machine-dry or iron your period underwear. No fabric softener or bleach too, please.

Can I wear my period underwear without any pads?

Yes, you can. Our period underwear can hold up to 4 tampons worth of menstrual fluid and are great for regular to light flow or at the end of your menstrual cycle. You can also use it as a backup with your pad, tampon or menstrual cup to prevent messy leaks and stains during heavy flow days.

How does the period underwear work?

REFINED period underwear are designed with 4-layer super absorbent and moisture-wicking, leak-proof layers. These layers absorb your period fluid and keep the surface dry - so that you can breeze through that time of the month like any other day.
