What makes Cheeki different
Built for teens. Trusted by moms.
Soft bamboo viscose for sensitive skin
Most period underwear uses synthetic or cotton-blend fabrics. Cheeki uses viscose made from bamboo — soft, breathable, and gentle against skin through a long day of wear.
Made without PFAS
Independent testing has found PFAS "forever chemicals" in some period products. Cheeki is made without intentionally added PFAS or harmful dyes, and our fabric is OEKO-TEX Standard 100 certified.
Breathable through a long day
Bamboo viscose is breathable and moisture-wicking, so she stays comfortable and feeling fresh through school, sports, and overnight wear.
School-ready carry case
The kit includes a discreet carry case so she's always prepared — at school, at practice, or sleeping over at a friend's house.
Absorbency for her heaviest days
Each pair holds up to 50ml and is designed for up to 12 hours of wear. Three styles cover every situation — heavy days, lighter days, and active wear.
Less waste, every cycle
A teen can go through thousands of pads and tampons. Cheeki is washable and lasts 2+ years, replacing hundreds of disposables along the way.
Join hundreds of teens who finally have their period handled.

The Teen Starter Kit includes everything she needs to get started with confidence — three pairs plus a discreet carry case. The Bamboo Overnight Brief handles her heaviest days and overnight; the Seamless Low-Rise Brief is made for school, sports and everyday wear, invisible under leggings and uniforms; and the Seamless Hi-Rise Brief in Sky sits high and stays put through a full school day. The Cheeki Carry Case keeps her prepared at school, at practice, or at a sleepover. All three pairs hold up to 50ml and provide 8–12 hours of leakproof protection — a full day with no backup needed.
Start with the Seamless Low Rise Brief on a lighter day so she can get comfortable with how it feels. Once she sees how easy it is, the Bamboo Comfort Brief for heavier days will feel like second nature. Most moms tell us the transition was much smoother than expected — and their daughters never looked back.
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.
This kit has both a bamboo pair and a seamless pair that is not. Bamboo is naturally softer, more breathable, and gentler on sensitive skin — ideal for teens new to period underwear. It's also naturally antimicrobial for freshness during long school days, and biodegradable, making it better for the planet too.
No — Cheeki is designed as a complete replacement for pads and tampons. Both styles hold up to 50ml and provide 8–12 hours of protection, covering a full school day. No backup needed. On very unpredictable first periods, some girls add a liner for extra peace of mind while they're getting comfortable.
Check the Cheeki size chart on this page — all styles fit similarly, so choose the same size across both pairs. If she's between sizes, size up for the most comfortable fit. Still unsure? Reach out to us at cheekiwear.com and we'll help.
Yes! The Teen Bamboo Comfort Brief is perfect for overnight use — maximum absorbency and full coverage means total peace of mind while she sleeps. No more waking up to check. No more ruined sheets.
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.
Every mom who bought this said the same thing: "I wish we'd done this sooner."
