Absorption Capacity – Heavy Flow, No Marketing Fluff
LY1394 is built for heavy flow days—real heavy, not “marketing heavy.” It holds significantly more than our moderate styles, enough that you can actually sleep through the night or get through a long workday without thinking about it. Here’s the honest truth: some customers need max protection. This is for them. For brands, this is your heavy-hitter option for customers who’ve been let down by “heavy flow” claims that didn’t deliver.
Fabric – Natural Bamboo, OEKO-TEX Certified
The main fabric is bamboo—and not because it’s trendy. Bamboo menstrual panties are naturally antibacterial, so odor doesn’t build up even on heavy 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 a product customers actually trust. Plus it’s true to size and comes in multiple colors—because heavy flow protection shouldn’t mean sacrificing style.

I've never tried menstrual panties before. Will these feel bulky?
Nope. That’s the whole point of modern menstrual underwear for women—it’s not your mom’s old-school protection. The absorbent layer is thin and flexible, so it moves with you. You’ll feel protected, not padded. Most people forget they’re wearing anything different by lunchtime.
How do I wash these without ruining the absorbency?
Cold rinse first (hot water sets stains), then machine wash cold with similar colors. Two big don’ts: no fabric softener (it coats the absorbent layer and kills performance), and no dryer (heat damages the waterproof layer). Hang dry only. Follow that and they’ll last years.
I'm a buyer for a boutique. What's your track record with delivery dates?
We hit our deadlines. After 34 years, we know how to plan production, how to source materials, and how to communicate if something shifts. We’re SEDEX certified, which means our whole operation is audited for ethics and reliability. If we say 60 days, it’s 60 days. For custom menstrual underwear, we build timelines you can count on.
Do you offer sustainable packaging for private label orders?
Yes—and we’ve been doing it before it was trendy. Recyclable boxes, minimal plastic, options for compostable bags if you want them. We can match your brand’s sustainability goals. Just tell us what you need. We’re flexible like that.
