  • Jessica J

    I bought myself a few pairs and I'm not kidding when I say they are so comfortable and fit perfect, I would wear them every single day!!! I feel so good about replacing all the pantyliners I use when I am on my period. Thank you Saalt!

  • Euna

    I wanted to avoid panty lines and the bulk of pads while still wearing leggings at the gym. My solution was Saalt's seamless underwear. I was skeptical at first, but honestly they're very thin and comfortable making it the perfect thing to wear under leggings.

  • Michelle C.

    These are great! The period panties I've ordered from other brands feel like thin diapers mixed with granny panties. These are cute, they work, and I'm definitely going to buy more!

Customer Reviews (4.8 / 5 · 5 reviews)

Scarlett T. ★★★★★

I was nervous about light leaks ruining my favorite jeans, but the full coverage and absorbent cotton layer have honestly given me total peace of mind during long workdays. They hold up wash after wash without losing shape, which is exactly what I needed.

Brian B. ★★★★★

I was skeptical about leakproof underwear being worth the hype, but the full coverage stays put all day without bunching or riding up. It handles my light bladder leak moments completely invisibly, and the cotton breathes well enough that I forget I'm wearing it.

Zoe ★★★★★

The cotton feels genuinely soft against my skin, and the full coverage stays put all day without rolling or bunching. I wore them through a long work shift and completely forgot I had them on, which is exactly what I wanted for everyday protection.
