Absorption Zone – Extended to Waistband, Zero Gaps
Here’s what makes LY999 different: the absorption zone extends all the way to the waistband. Front and back. That means when you’re sleeping on your side or curled up, you’re still covered. No gaps where leaks can escape. For overnight period underwear, this kind of coverage is a game-changer. You can actually relax and not worry about waking up to a mess.
Natural Bamboo with Antibacterial Properties
Main fabric is bamboo—not because it sounds nice, but because it works. Bamboo period panties are naturally antibacterial, so odor doesn’t build up even on the heaviest days. It’s breathable (so you don’t overheat), soft against skin, and holds up wash after wash. Whole thing’s OEKO-TEX certified and PFAS-free. For buyers, that means clean materials, easy market compliance, and high absorbency period underwear customers actually trust.

How much can the LY999 actually hold?
this is our maximum absorption style. It holds significantly more than our moderate options—enough for overnight wear and your heaviest days without leaks. If you’ve been doubling up with pads or waking up to change, this is the upgrade.
What does "absorption zone extends to waistband" mean?
Most period underwear stops mid-way. LY999 keeps going—the absorbent layer runs all the way to the waistband, front and back. So if you sleep on your side or move around at night, you’re still covered. No gaps, no leaks.
