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.

    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

Overall rating: 4.1 / 5 from 588 reviews.

I love that I can hardly tell I am wearing them!

Love everything about this brand! Excellent quality and high confidence while wearing them. I use them for occasional incontinence security. Welcomed option and feel fresh at the end of the day!

They work great and are super comfy, this style/fabric combo has not tore away from the seam like other styles from Saalt that I have.

I’m new to free bleeding and I couldn’t be more excited! My cramps hurt less and these underwear have already made my relationship to my period stronger and more beautiful. Thank you for making this product!!

Didn’t wanna show too much but I LOVE this brand! This is the Heavy absorbency, which holds 4 tampons or 3 pads. And I promise it’s true! I pushed the ones pictured to just over 13 hours and they only leaked at the edges just this little bit and none of it got on my clothes, which surprised me. Anyway, if you’re on the fence, go ahead and jump over!

Great product; I tried it and then ordered more.

Product is awesome. Shipping took almost a month, which was super annoying.

Probably my favorite pair. Very comfortable and fit well

Absolutely love the undies. But oh my GOD why have you emailed me at least 20 times asking me to review them. I'm literally only doing it now so you will leave me the f*** alone. PLEASE STOP EMAILING ME

Used for trip to Italy in July. These were nice under my light clothing. It was so hot and these worked - you know what I mean. Also, washed easily and air dried them over night.

Love the clean seamless design, feel and look! These feel buttery smooth and compliment the body.

Best period undies ever!

Love these undies so much. Very soft, seamless and secure.

the xs fit perfectly so grateful for the exchange and looking forward to wearing them when we travel.

I feel the need to have some leakage support and hate hate hate pads especially because I usually wear thongs. These briefs are perfect so thank you!

The material is great. Thin, soft, and the absorbency hasn’t failed me once. They fit true to size. I’m between a L and XL, ordered a L.. and they fit great.

Love these! I bought several pairs of period underwear and use them every month!

These are great; you can't see this underwear under clothes and they don't ride up. I wear them as backup, so I can't attest to their capacity and feel for a full period.

Feels light, which I'm not used to with Period Underwear and the absorbency level I need!

fits perfect, great for all day wear and active wear!

fits perfect, super comfortable for all day and active wear!

These are not only great for period week but amazing for sweat control, I’m hooked!

Love the comfort of these underwear!

Love them! Perfect as backup during workouts.

Great fit

These are so comfortable! I will never go back and these are the best brand of period underwear I have found!

Perfect for exercising!

Perfect for exercising!

This is by far my worst experience EVER with bying anything online! I ordered the teen cup and it was missing from the delivery. I reached out by mail 3 times and only answered by bots who did not give me a chance to get a replacement item. I also reached out by phjone and was again answered by bots, who did not allow a replacement item. Stay away - you're wasting your money on products you won't receive!

These are amazing for more than just periods, they are perfect for sweat control in the summer. These are absolutely a new staple!!

These are the most comfortable pair I own! I wore them while running and felt confident and comfortable.

These are the most comfortable period undies I've ever bought, also extremely absorbent and keeps me dry. My favorite pair from Saalt

great product! kept me dry and didnt trap heat as i tend to sweat on my period.

I love these! They are smooth, they provide excellent coverage and protection on my medium to light days and they don't feel like period underwear.

Thin, effective and discrete

This was my first time trying period underwear. I used them to sleep with their cup and as a back up at the gym. They are great! Comfortable, reliable, and didn't look weird under yoga pants!

These are my favorite period underwear! They are very absorbent but thin and I barely feel that they are there. They are completely invisible under my pants.

These are so comfortable, even on the heavier days.

These are so comfortable, even on the heavier days.

So comfy, fit like a glove and kept me dry all night on the heaviest night of my period!
