    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!

Madison D. ★★★★★

The absorbency layers sit exactly where they should, so I never worry about that dreaded damp feeling on warm days. The cotton's smooth against my skin and the slightly cheeky cut is actually flattering under jeans.

Jacob O. ★★★★★

I was skeptical about cotton absorbency holding up, but the super option genuinely kept me dry through a full workday with zero visible marks on my trousers. The fabric feels like a normal soft bikini, not a pad, and the cheeky cut is actually flattering. Wore it on a hot commute and forgot I had an

Steven ★★★★★

The regular absorbency handled my entire workday without me ever thinking about it, and the cotton fabric felt genuinely breathable instead of sweaty. The cheeky cut is flattering, but the real win is that I can finally wear light-colored pants with zero stress.
