Frequently Asked Questions (FAQs)
Yes — completely. Cheeki is PFAS-free, free of harmful dyes, and OEKO-TEX certified. Every component has been independently tested and verified to be free of harmful substances. What touches your daughter's skin should be safe — full stop.
Medium flow holds the equivalent of 2–3 regular tampons or pads — perfect for lighter period days, the tail end of her cycle, or teens whose flow is still settling into a regular pattern. If her flow tends to be heavier, especially on day 1 or 2, we'd recommend pairing this with our Heavy Flow styles for those days
On medium flow days, most girls wear these comfortably for 8 hours — covering a full school day with ease. Flow varies from person to person, so we recommend she gets familiar with her own cycle to find the wear time that feels right for her.
The Classic Seamless High Rise is made with soft, breathable fabric that is gentle against the skin all day — no scratchy seams, no synthetic plastic layers, no irritation. OEKO-TEX certification means every material has been independently tested to meet strict safety standards, making it a great choice for teens with sensitive skin.
On medium flow days, no — these are designed to be worn on their own as a complete replacement for pads and tampons. No backup needed. On heavier days we'd recommend switching to a Heavy Flow style for full coverage and peace of mind.
Absolutely. The seamless high rise design is smooth, invisible under clothes, and flexible enough to move with her through gym class, sports practice, and everyday wear without shifting or bunching. The high rise waistband also provides extra coverage and security during active movement — no adjusting, no worrying.
Cheeki underwear is easy to care for. After use, rinse in cold water until the water runs clear, then machine wash cold with like colors. Tumble dry low or air dry. Avoid bleach and fabric softeners to maintain absorbency and extend the life of your underwear.
