Mid-Waist Seamless Period Underwear LY1229

 

Mid-Waist Seamless Shape
Not everyone loves a high waist. The LY1229 hits right at the mid-waist—that sweet spot between low and high that most women actually prefer. The seamless period panties construction means no visible lines under clothes and zero irritation. Just a smooth, flattering fit that works for real bodies.
Stretchy Nylon Fabric – Actually Comfortable
Made from high-elastic nylon that stretches when you need it to and snaps back after washing. No baggy knees, no sagging. It’s comfortable period underwear that you can wear all day and literally forget you have on.
1/2 Leak Proof Coverage – Medium Absorption, Less Bulk
Here’s the thing: not everyone needs full coverage. LY1229 has 1/2 leak proof coverage—enough for moderate flow days without the bulk of full-coverage styles. It’s thinner, lighter, and breathes better. Perfect for everyday wear when you want protection but not a diaper feel.

Absorption Zone – 1/2 Coverage, Strategically Placed
Most brands either give you full coverage or nothing. We designed LY1229 with 1/2 leak proof coverage that’s strategically placed where you actually need it—not too much, not too little. The absorbent layer hits the right spots without extending into areas that don’t need it. That means less bulk, better breathability, and a more natural feel. For everyday period underwear, this is the sweet spot.

Absorption Capacity – Moderate Flow, Realistically Rated

LY1229 is moderate flow period underwear—holds 20-30ml, which is roughly 3-4 regular pads. It’s perfect for regular days, as backup, or for lighter flow days. Here’s the honest truth: not every customer needs maximum absorption. This is your core everyday option that fits most people’s needs without extra cost for absorbency they won’t use. For brands, that means happier customers and better margins.

Fabric – Seamless Nylon, Breathable and Stretchy

The main fabric is seamless nylon-spandex—soft, stretchy, and quick-drying. No seams means no chafing and no visible panty lines. It’s breathable period underwear that doesn’t trap heat, so you stay comfortable even on warm days. Whole thing’s OEKO-TEX certified and PFAS-free. For buyers, that means clean materials, easy compliance, and a product customers actually want to wear.

still have questions?

we have answers

“1/2 coverage” means the absorbent layer is strategically placed where you need it—front to back in the gusset area—but doesn’t extend into the sides or waistband. For moderate flow days, it’s plenty. You get protection where it counts without the bulk of full-coverage styles. Think of it as the difference between a heavy-duty pad and a regular one. Both work, just for different needs.

Regular period underwear has seams that can dig in, irritate, or show under clothes. Seamless period panties are knit in one piece—no side seams, no irritation, no VPL. They move with you instead of against you. Once you try seamless, it’s hard to go back.

Nope. The waterproof strips are soft and flexible—they don’t crinkle or rustle like old-school waterproof materials. You can wear them under leggings, skinny jeans, whatever. No one hears a thing.

Absolutely. We work with brands of all sizes. For custom period underwear with your branding, MOQ is 1000 pieces per style per color. But we also keep stock styles with no minimum—you can order as few as 10-20 pieces to sample, photograph, or test the market. We’d rather you grow with us than commit to something you’re not ready for.
