Care Instructions

After use, rinse your Saalt Wear leakproof underwear in cold water to help avoid staining. Then, hand wash or machine wash on cold, preferably in a Saalt Mesh Laundry Bag intended for delicates. You can use detergent but pass on the fabric softener, bleach, or iron to protect the tech. Proudly hang dry—energy efficient and free. We recommend avoiding putting Saalt Wear in the dryer, as high temperatures can degrade the elastics and fabric over time.

90-Day Saalt Bliss Guarantee

    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!

Overall rating: 4.3 / 5 from 404 reviews.

Super comfortable, held up in a mid flow full day and the fit is perfect.

Leakproof Cotton Brief

love these chonies! Also, I have tried so many different cups, and the Saalt cup is by far the best one. It fits me so well. Im grateful!!

Leakproof Cotton Brief

Comfortable, felt like normal underwear. Leak proof

Leakproof Cotton Brief

These underwear have changed the period game and I couldn't be happier! Wish I would have had these in Jr high!!

Leakproof Cotton Brief

I bought this color to be able to wear under thin or light colored dress pants but was worried that they would get stained/gross looking over time with use. The inside where a pad would normally is black so it looks no different after being washed

Leakproof Cotton Brief

I bought the Saalt underwear to supplement my disc, because I bought the disc so I wasn’t going through tons of disposable products each period, but I was still having to wear liners or pads because of any leakage, especially at night. I also love these so much more than pads because there’s no crinkling sound with any movement. Being machine washable also makes them very easy to use

Leakproof Cotton Brief

Look and feel is perfect. Much softer than competitor brands, truly no line, very pleased with this product

Leakproof Cotton Brief

The most comfortable pants I have ever owned! Such a smooth feel, feel very supported during the second and third day of my flow. Still need my mooncup for the first day. But these are great. Will definitely buy again!

Leakproof Cotton Brief

Awesome help via customer service and love the products

Leakproof Cotton Brief

These fit well and protect me on my heaviest days! I prefer them in black.

Leakproof Cotton Brief

It fit so well, it’s so thin and comfortable! On my heaviest day, it lasted a whole 7 hours before showing signs of overflow. Also, the padding inside kept me dry the whole time. Amazing! I love the high coverage in the front and extra in the back! I bought from Saalt looking for clean, non-toxic materials, and I am super satisfied

Leakproof Cotton Brief

They fit nice and the gusset actually covers the right area now.

The material is stretchy and soft! Excited to try them out!

Leakproof Cotton Brief

Best period panties ive ever tried. Feel like regular underwear and very durable. Lasted all day on day two of my period which is my heaviest flow day. Will be buying more!
