FAQ
Everything You Need to Know About Siamora
Siamora features a built-in heating system positioned on the lower abdomen. Once in contact with the skin, it emits a gentle, consistent warmth that helps relax the abdominal area during your period.
Heat is known to provide natural relief from menstrual cramps. Siamora was designed to deliver this soothing effect continuously, without the need to hold a hot water bottle against yourself.
Rest assured: its thin, low-profile material makes it completely invisible under clothing. You can wear it discreetly, no matter your outfit.
Check our size guide on the product page. Siamora is available from S to XXL, with a high-waisted fit that holds you in without compressing.
Wash Siamora like a regular pair of panties: machine wash at 30°C on a delicate cycle, without bleach. Allow to air dry to preserve the fabric and the effectiveness of the heating system.
You have 30 days to return it to us for a refund, with no justification required. An exchange for a different size or color is also possible at any time.
