Second-skin, seamless fabric
50 ml — 4–5 super tampons
Absorbent side walls
Quality & transparency
OEKO-TEX certified fabrics with GOTS organic cotton lining in direct contact with your skin.
The entire panty is certified. Class II covers textiles in direct skin contact — the strictest safety standard.
Certificate no. 2026OK1834 — issued by AITEX
The layer touching your skin is made of GOTS certified organic cotton, the most demanding standard in organic textiles. No pesticides, no GMOs.
No seams. No lines. No one knows.
Liv is our seamless style, cut from an ultra-thin second-skin fabric that disappears under everything — leggings, tailored pants, a slip dress. The kind of underwear you stop thinking about.
Don't let the thinness fool you. Liv holds 50 ml, the equivalent of 4 to 5 tampons, with leak barriers built into the sides of the absorbent core. It's made for heavy days, worn for hours.
The absorbent panel sits high and central, so Liv is the right pick if your flow runs central rather than toward the back. Wear it through a full workday, a long flight, a heavy night.
Liv also works for light bladder leaks — during pregnancy, postpartum, or through menopause.
Available in sizes XXS to 3XL. Our model wears a size S.
Rinse in cold water right after wearing — cold water first, always.
Machine wash at 86°F (30°C) with the rest of your laundry. No fabric softener.
Air dry. Never tumble dry.

Honestly, I'm blown away. My flow is really, really heavy, and even after going to the bathroom you stay dry — none of that wet feeling. And in this heat it's so light. I love it, I ordered a second pair because I liked it that much. I really recommend these, they're a safe bet.
These are the best period underwear I've tried, and I've tried a lot. They're incredibly thin but they absorb amazingly well — and my flow is pretty heavy! Even the first or second night, which can be an actual Niagara Falls situation, nothing leaks through.
Really happy with these. On my worst day I'd stopped going out because it always ended in a leak. Two cycles in, no problems at all. It's amazing.
So good! It feels strange at first when you're not used to it, but they're genuinely comfortable, no leaks, I sleep with a clear head and my first days are so much easier.
Good absorption, very comfortable — probably because there are no seams. I'm usually a M but I went up to L and I don't regret it.
Brilliant. No odor. Very absorbent, no damp feeling.
Simply perfect. After the first pair, a second order was a no-brainer.
I've been using them for a few months now and honestly it beats pads. The texture fascinates me, so comfortable. The only thing is I thought they'd hold more than 5 hours on heavy days — but I don't mind changing at 5 hours when my flow is building.
