It’s a boyshort period underwear cut—so it covers more, stays put, and doesn’t ride up when you’re tossing and turning all night. Think sleepwear pants, but make it period protection. Roomy enough to be comfy, fitted enough to actually work.
Super Heavy Flow Absorption
This isn’t for light spotting days. LY764 is built for super heavy flow period underwear—holds way more than our moderate styles. Whether it’s overnight or your heaviest day, you’re covered. No waking up to leaks, no stressing at work
Natural Antibacterial Bamboo Fabric

Absorption Zone – Full Front-to-Back Coverage

The absorbent layer runs the entire length of the gusset—from front waistband all the way through the back. No gaps, no bare spots. It’s shaped to match the body so it stays put whether you’re sleeping on your side or moving around all day. For overnight period underwear, this kind of coverage is everything.

Absorption Capacity – Super Heavy Flow, Honestly Rated

We don’t play games with absorbency numbers. LY764 is super heavy flow period underwear built for the heaviest days and overnight wear. Holds significantly more than our moderate styles—enough that you can actually sleep through the night without setting an alarm to change. For brands, this is your heavy-duty option for customers who need real protection.

Fabric – Natural Bamboo with Antibacterial Properties

Main fabric is bamboo—and not just because it sounds nice. Bamboo period panties are naturally antibacterial, so odor doesn’t build up even on heavy days. It’s breathable (less sweating), 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 a product customers actually trust.

Who Is It Designed For

Daily Wear
Designed for everyday comfort, our period underwear helps manage daily vaginal discharge and light moisture. Breathable fabrics and a thin absorbent layer keep wearers feeling fresh, clean, and confident throughout the day without bulk.
Menstrual Use
Engineered for reliable protection during light to heavy menstrual flow, the multi-layer absorbent core locks in fluid and prevents leaks. Suitable for standalone use or as backup protection, depending on flow level and design.
Pregnancy & Postpartum Use
Thoughtfully designed to support pregnancy and postpartum needs, including increased discharge during pregnancy and lochia after childbirth. Soft, stretchable fabrics offer gentle support and comfort during sensitive stages.
Light Bladder Leaks
Ideal for women experiencing light urinary incontinence, our underwear provides discreet absorbency and odor control while maintaining the look and feel of regular underwear for everyday wear.

MOQ is 1000 pieces per style per color for full custom. We also keep stock styles with no minimum if you want to sample or test small batches first.

We’re OEKO-TEX certified, fabrics are PFAS-free, and we’re SEDEX certified for ethical manufacturing. Facility is 68,000m², 700+ employees, 1.5 million units monthly production. We can provide all the compliance docs you need. If you’re looking for a period underwear wholesale partner who actually makes the product, that’s us.
