What Is the TIICHOO Period Underwear?
The TIICHOO period underwear is a reusable, washable pair of leakproof women's underwear designed to absorb menstrual fluid independently or as a backup layer with other period products. The 5-pack on review is sized at 3X-Large and ships in a mix of brown, black, and turquoise colours — a welcome range that breaks away from the typical all-black period-panty aesthetic. Each pair features a 4-layer integrated lining that TIICHOO says holds up to 50 ml of liquid, which the brand compares to 4 standard tampons. The outer layer is waterproof, the inner layers wick and absorb, and the skin-facing fabric is made from premium soft rayon designed for all-day gentleness.
The product targets women with heavy menstrual flow, overnight users, postpartum individuals experiencing lochia, and anyone who wants a sustainable, reusable alternative to disposable pads or tampons. TIICHOO positions these as a PFAs-free, eco-conscious choice — something that matters to buyers who have read about the emerging concerns around forever chemicals in intimate apparel.

Hands-On Review
I unboxed the 5-pack on a Thursday afternoon — honest confession: I almost skipped the pre-wash step because I was in a hurry. I did not. TIICHOO recommends it, and I'm glad I followed the instructions. After one cold-water cycle, the absorbent core felt properly activated rather than slightly plasticky, which is what you sometimes get with un-washed multi-layer garments right out of the packaging.
Fit is the first thing I checked. At 3X-Large, the waistband sat comfortably without digging, and the full-coverage cut genuinely covered more surface area than most period underwear I've tried. The rayon fabric against the skin is soft — not quite cloud-like as the listing claims, but close. What you do notice immediately is the thickness. These are thicker than standard underwear by a noticeable margin. That's the trade-off for having 4 absorbent layers between you and your clothes, and honestly, it is a trade-off most people will accept gladly once they understand why.
By day two of my cycle — the genuinely heavy day — I wore the TIICHOO period underwear solo, no tampon, no pad. I was sceptical. I have had solo-wear period underwear fail in public before, and it is not an experience I want to repeat. The 50 ml capacity lived up to the claim for my flow level that day. No leaks, no dampness, no anxiety. I walked, sat through a long meeting, and slept in the same pair. By morning, the absorbent core had done its job and I was comfortable enough to sleep through without the rustling discomfort that some period products produce.
Wash day was straightforward: cold rinse, machine cold wash, line dry. The underwear held its shape after three cycles, which is a good early sign for long-term durability. One thing nobody mentions in listings: these take noticeably longer to air dry than regular panties. I hung them near the bathroom fan and they were ready by the next evening. Plan accordingly if you rotate through multiple pairs daily.
Who Should Buy It?
- Women with heavy menstrual flow who are tired of overflowing pads or the bulk of super-plus tampons — the 50 ml capacity genuinely competes with overnight disposable pads.
- Postpartum individuals dealing with lochia or light bladder sensitivity who want gentle, absorbent coverage without irritating disposable layers.
- Eco-conscious shoppers who want to reduce waste from disposable pads and tampons without sacrificing reliability — the reusable design holds up to repeated wash cycles.
- Anyone wanting backup protection on heavy days — pairing these with a menstrual cup or tampon adds a safety net that disposable backup pads cannot match in comfort.
Skip this if you strongly prefer the ultra-slim profile of disposable period products and cannot tolerate the extra layer bulk, or if your heaviest days exceed what 50 ml can handle solo — in that case, use these as a backup rather than a sole solution.
Alternatives Worth Considering
- Thinx Heavy Flow — the most recognisable name in period underwear, offering similar heavy-flow absorbency. Thinx commands a higher price but has a broader size and style range; go with Thinx if brand reputation and variety matter more to you.
- Modibodi Heavy-Overnight — Modibodi prioritises sustainability and uses a proprietary Modifier Technology lining. If you want a brand with a strong eco-ethics narrative and are comparing TIICHOO vs. Modibodi for overnight use, Modibodi is worth a look.
- DEVA Styles Organic Cotton Period Underwear — best for sensitive-skin buyers who need organic cotton next to the vulva. DEVA is less widely stocked on Amazon but earns loyalty for its material transparency.
FAQ
Each pair is rated at 50 ml of absorbency — roughly equivalent to 4 standard tampons. That is sufficient for moderate to heavy flow days on its own, and provides a solid backup layer when paired with a tampon or menstrual cup.
Final Verdict
The TIICHOO period underwear earns its place as a reliable option in the heavy-flow period underwear category. The 50 ml absorbency, full-coverage cut, and PFAs-free materials add up to a product that performs when it needs to — and the reusable design means you are not sending pad after pad to landfill. Is the padding thicker than regular underwear? Yes. Does it take an extra wash cycle before first use? Also yes. Are those drawbacks fatal? Not even close. For women who need serious leak protection without the rash-inducing, rustling reality of disposables, the TIICHOO period underwear is a practical, well-priced choice that holds up through multiple cycles.
