Absorption Zone – Full Coverage, Seamless Construction
The absorbent layer runs the full length of the gusset—front to back, no gaps. But here’s the tricky part: building absorbent layers into seamless period underwear is harder than it looks. Most brands can’t do it without adding bulk or breaking the seamless construction. We figured it out. The absorbent zone is there, you just can’t feel it.

Absorption Capacity – Moderate Flow, Honestly Rated
LY2042 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 – Seamless Nylon with French Lace
The main body is seamless nylon-spandex—soft, stretchy, and completely smooth under clothes. The waistband features genuine French lace that’s soft against skin (not scratchy like cheap alternatives). The leak-proof layer is our best-selling technology that controls blood, sweat, and odor. Whole thing’s OEKO-TEX certified and PFAS-free. For buyers, that means clean materials, easy market compliance, and no show period panties that customers actually want to wear.

Will the French lace show through thin leggings?
Nope—that’s why it’s at the waistband, not down the sides. The lace sits right at your natural waist, which is usually covered by waistbands anyway. If you’re worried about it, wear it with mid-rise pants and you’re fine. It’s invisible period underwear where it counts.
I'm a boutique owner looking for something different than what's on Amazon. Is this exclusive?
It can be. We do private label period underwear for lots of boutiques that want to stand out from the mass-market stuff. French lace and seamless construction is a combo you don’t see everywhere. Pick your colors, your packaging, your tags—make it yours. MOQ is 500 pieces per style per color for full custom.
how long does the seamless construction last before it starts bagging out?
If you take care of it? Years. The key is no fabric softener (coats the fibers and ruins stretch) and hang drying (heat breaks down elastic). We’ve tested these through 50+ washes and they still snap back. Cheap seamless falls apart. Ours doesn’t.
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.
