Absorption Zone – Strategically Placed, Full Coverage
The absorbent layer runs the length of the gusset—front to back, no gaps, no bare spots. But because it’s cheeky period panties, we shaped it to follow the cut of the style.

Absorption Capacity – Moderate Flow, Honestly Rated
LY2019 is built for moderate flow days—holds 20-30ml, which is roughly 3-4 regular pads. Here’s the honest truth: this is our best-selling absorbency level for a reason. It fits most people’s needs most days of their cycle. For brands, this is your core SKU—the one that’ll sell year-round, not just on heavy days.
Fabric – Seamless Nylon-Spandex, OEKO-TEX Certified
The main fabric is seamless nylon-spandex—soft, stretchy, and quick-drying. No seams means no VPL and no irritation. It’s invisible period panties that actually disappear under clothes. The leak-proof layer is our best-selling technology, tested to control blood, sweat, and odor. Whole thing’s OEKO-TEX certified and PFAS-free. For buyers, that means clean materials, easy market compliance, and leak proof menstrual underwear customers actually trust.

Natural odor control, fresh all day
You say it controls sweat and odor—how? Does it have chemicals?
No chemicals. The magic is in the layers. The fabric is designed to wick moisture away from your body (that’s the sweat part), and the absorbent layer traps odor before it becomes a problem. Plus bamboo is naturally antibacterial. No perfumes, no weird treatments, just smart engineering.
I've tried seamless underwear before and it rolled up. What's different here?
Cheap seamless rolls because the elastic isn’t anchored right. Ours has stabilization built into the edges—you can’t see it, but it keeps everything in place. The seamless period underwear market is full of junk, we know. That’s why we spent time getting it right before launching.
I'm a boutique owner. What's your lead time on custom orders?
For custom menstrual underwear with your branding, lead time is typically 60-75 days from sample approval, depending on quantity. For stock styles with no minimum, we can ship within 7-10 days. We’re honest about timelines—if it’s going to take 75 days, we say 75 days. No last-minute surprises.
