Absorption Capacity – Moderate Flow, Honestly Rated
LY2021 is built for moderate flow days—holds 20-30ml, which is roughly 3-4 regular pads. Here’s the honest truth: this is the absorbency level most women need most days of their cycle. For brands, this is your core SKU—the one that’ll sell consistently year-round, not just on heavy days.
Fabric – Twill Crotch with Stretchy Nylon
Here’s what makes this different: the crotch is twill fabric, which has a diagonal weave that’s more absorbent and quicker drying than standard knits. It pulls moisture away from your body and keeps the surface feeling dry. The rest of the underwear is stretchy nylon-spandex—soft, breathable, and shape-retentive. Whole thing’s OEKO-TEX certified and PFAS-free. For buyers, that means clean materials, easy market compliance, and bikini period panties that actually feel like real underwear.

What's a "high cut" leg? Will it feel like a thong?
No, not at all. High cut just means the leg opening comes up higher on your hip—it’s actually really flattering because it makes your legs look longer. Think 80s swimsuit vibes, not thong territory. Still full coverage in the back, still comfortable, just a different silhouette.
Twill fabric? Isn't that for pants?
Ha, fair question. Twill is a weave, not a specific fabric weight—it’s how the threads are woven together (diagonal vs straight). For period underwear, twill weave actually works great because it’s more absorbent and dries faster than regular knit fabrics. We didn’t invent it, but we’re one of the few using it for twill crotch period underwear.
What does "unscented" mean? Do other brands add perfume?
Some do, yeah—to cover up odor. But perfumes can irritate sensitive skin and they’re just masking the problem. Ours is unscented period panties because the bamboo and absorbent layers control odor naturally. No chemical smells, no irritation, just clean.
How do you keep the high-cut legs from leaking? Seems risky.
Another good question. The secret is in the waterproof strips on the sides—they run along the leg openings so even with less fabric, leaks can’t escape. Plus the absorbent layer is shaped to follow the cut, not just a straight rectangle. We’ve tested it. It works.
