The easiest way to find your Oya.

The Oya Starter pairs our Brief with our High Waist, so you can try both styles and find the one that feels like yours. Wear one while the other's in the wash: that's your period covered from day one.

What's inside

  • 1 × Brief (mid-waist)
  • 1 × High Waist

Both pieces come in the size you choose. Not sure which size? Check our size guide before you order.

Shipping

Orders are processed within 1-2 business days. Standard delivery within Thailand typically takes 2 business days, while international orders can take 7-14 business days depending on the destination.

Returns & warranty

Finding the right fit is important. If your Oya underwear isn't quite the right size, we're happy to offer a size exchange, provided the hygiene seal remains intact, the product tags are still attached.

For hygiene reasons, we do not offer refunds. Size exchanges are only available for items with an intact hygiene seal and attached product tags.

If you receive a faulty item, please contact us within 14 days.

How does it work?

Oya uses a multi-layer protection system: a moisture-wicking top layer, an absorbent core that holds up to 30ml, a waterproof barrier for leak-free confidence, and a soft, breathable outer fabric.

Simply wear Oya like your regular underwear and let the built-in protection do the work.

How much can it hold?

Both our Brief and High Waist styles can absorb up to 30ml of liquid, equivalent to around 4 regular pads*

*based on an average absorbency of 7ml per pad

How long can I wear it?

Oya can be worn for up to 12 hours, depending on flow and activity level.

If you have a heavier flow, you may need to change more frequently.

Why Oya?

  • For Women by Women

    Every Oya purchase helps build something bigger than a product - a community that celebrates women, challenges period stigma and believes comfort should never come with compromise.

  • Free from PFAS

    Made without added PFAS ("forever chemicals"), a group of chemicals that have been linked to hormone disruption and other health concerns. Just soft, comfortable materials designed for everyday wear.

  • Machine washable, made to last

    Rinse, wash cold and reuse. With proper care, Oya is designed to last for years.

  • Better for you. Better for the planet

    By switching to Oya, you're helping reduce single-use period waste. Crafted from soft, breathable TENCEL™ Modal fibres sourced from responsibly managed forests, Oya is designed with both your comfort and the planet in mind.
