Description
Liv's everyday sister.
Gaby is the same seamless construction — no edges, no lines, second-skin fabric — built for a medium flow instead of a heavy one. It holds 30 ml, the equivalent of 3 tampons.
Wear it through a normal day, or at the very start and very end of a heavier period. Under leggings, a pencil skirt, skinny jeans: nothing shows. The absorbent gusset stays genuinely thin.
Black, simple, and easy. The kind of pair you reach for without deciding.
Available in sizes XXS to 3XL. If you're between sizes, take the smaller one — Gaby relaxes slightly after a few wears.

Great
Really high-quality and genuinely comfortable. Haven't had the chance to test the absorption yet but I can't wait to see.

Soft as a second skin
Really good, so thin, I feel light :)

★★★★☆
Good product
Comfortable, ultra-thin so very discreet under clothes, holds well with no leaks. For me it's ideal for a lighter flow toward the end of my period.

★★★☆☆
Fairly happy
I was looking for invisible period underwear. It mostly is under jeans, but not under thinner fabrics. I expected more absorption, though my flow has been very unpredictable since perimenopause. Overall I'm satisfied because the fabric is lovely. Now I just need to get used to a new kind of protection.
