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 video review of Leakproof Comfort Brief

My periods have been monsters. Day 2 and 3 are crazy. I have a hard time feeling "normal". No matter the pads I'm wearing, I always feel like I have to be close to a bathroom on those days and nights are even worse. But with these briefs, my stress level goes way down. I can rely on them. I can plan things again. They are so cozy and I just want to cry because they make my life easier. I will be buying more. Definitely.

Leakproof Comfort Brief

I use for incontenence and love the feel and the sense of security!

Leakproof Comfort Brief

These are the only period underware that feel soft, hold structure, and don't feel itchy.

Leakproof Comfort Brief

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.

Leakproof Comfort Brief

Love everything abouth them from comfort to how they wash.

Leakproof Comfort Brief

This was probably the best sleep I've ever had on my heaviest flow day. I had no leaks and it was honestly so comfy, totally changed the game for me.

Leakproof Comfort Brief

I was using a high waisted pair of thinx and they just didn’t fit my body the way that I needed them to. I decided I wanted to try something different so I tried SAALT. Ordered just a couple pairs to start, one brief and one bikini in a low rise. I tend to like the underwear to sit higher on my hips but I also prefer full coverage of my bottom. So I decided the briefs were what I would order more of but definitely will keep the bikinis. These are so soft, stretchy, and breathable and I don’t feel like I’m fighting them to fit me the way I need which is great! I can get through my day and don’t feel like I’m wearing a diaper!

Leakproof Comfort Brief

I purchased the Cotton Leakproof Briefs (Heavy absorbency). On my heaviest days, I either wear a tampon with them, or change more often (every 4-6 hours). I usually have 3 heavy days and 3 medium/light days; 6-8 hrs on lighter days when using these alone. At night I still wear a heavy pad, just in case, but then have this as extra protection. So far I haven't had any leaks. I'd eventually like to get more! They are so soft and comfortable.

Leakproof Comfort Brief

So comfortable and effective. Did not run into any issues when wearing all day

Leakproof Comfort Brief

These work better than I ever anticipated! They’re so soft and comfortable, and even with heavy bleeding (my periods have definitely gotten more intense in my 30’s), they never leaked!

Leakproof Comfort Brief

I have four different styles of Saalt underwear and these are my favorite hands down. They feel great on, so soft! The plum color is also really pretty.

Leakproof Comfort Brief

I've been using Saalt as my period panties for years. They're so perfectly soft, and never leak! Now, as I enter a new phase of life, my period panties are becoming my incontinence panties. I bought my mom several pairs, and made adult diapers a thing of the past. I intend them to be a thing of the never for me.

Leakproof Comfort Brief

Store owner replied: Thank you so much for sharing your journey with us. It is wonderful to hear that our Leakproof Comfort Briefs have been a reliable companion for you over the years, from your periods to this new phase. We are so happy that they could provide a more comfortable alternative for your mom as well. Your support means the world to us. ❤️🤩

Put on some weight so I had to order a new pair and I still live them just as much. I wear them as back now with my cup as I tend to have some leaking issues on day 1 of my period.

Leakproof Comfort Brief

Does exactly what it says it will! Comfortable, too.

Leakproof Comfort Brief

These are superb. They're soft, comfortable, and absorb well

Leakproof Comfort Brief

So comfortable, I no longer have to worry about spotting during perimenopause. Easy to clean too. I would highly recommend.

Leakproof Comfort Brief

Sooooo soft and comfortable!! The cotton brief is by far my favorite fit from Saalt. I use it either solo or in combination with the disc. The second my period comes on I reach for these right away. Keeps me dry and knowing through my day or sleeping through the night.

Leakproof Comfort Brief

Store owner replied: We are so happy to hear that the Leakproof Comfort Brief is your favorite fit. It is wonderful to know they provide you with comfort and confidence both day and night. Thank you for sharing how you use them alongside your disc. We truly appreciate your support. 🙂❤️

These are the best cycle panties I have tried so far. They feel the most normal, not like wearing a diaper or having a huge seam right across your cheeks. I would say I have a fairly regular flow nothing super heavy but I literally can't even tell and never feel wet. I can wear them all day and I don't get cramps like I do with a tampon. They actually also work great for those times when you sneeze or laugh too hard and a little drizzle comes out LOL. I don't worry that it's going to come out onto my pants. I didn't experience any wedges which I very much appreciate and they don't look like giant granny panties.

Leakproof Comfort Brief

Store owner replied: It is so wonderful to hear that the Leakproof Comfort Brief has become your favorite choice for your cycle. We are thrilled that they provide you with a normal feel and reliable confidence throughout the day, whether for your period or those unexpected little drizzles. Thank you for sharing how they have improved your comfort compared to other options. We love knowing that you can go about your day without any worries or discomfort. Your detailed feedback is truly appreciated. 🙂❤️

Obsessed with these!! I was looking for something overnight to replace the pads I was using. Even on my heaviest days, these keep me dry and leak-free through the night, and during the day, I use them as a backup with a tampon. They are so soft, and their colors are adorable. I've had them for a few months now, and after multiple washes, they hold up well. No more granny panties for me. Never going back! I just got 5 more pairs of various Saalt models to try, and I hope I love them as much as I love these.

Leakproof Comfort Brief

Store owner replied: It is so wonderful to hear how much you are enjoying the Leakproof Comfort Brief! We are thrilled that they are keeping you dry and confident through the night, even on your heaviest days. The TENCEL Modal fabric is indeed designed for that cloud like softness you mentioned. It is great to know they are holding up well for you after several washes. We hope you love your five new pairs of Saalt wear just as much. 🤩🤩🤩

I started my Saalt journey with the bikinis, but I like these more for how much more secure they feel. I would say they run a little big, but I am very happy with them so far.

Leakproof Comfort Brief

Store owner replied: Hi Lyria! Thanks so much for your review! We're sorry to hear the fit of the briefs wasn't quite right for you, though we're so glad to hear you're loving them otherwise. If you'd like to explore an exchange or return, you can find more information here: our replacement policy. You're also always welcome to reach out to our Saalt Coaches at [email protected]. We'd be happy to help you find a better fit. 🤗

I can wear this on day 2 and free bleed the whole time. It's so good! 10/10

Leakproof Comfort Brief

I was very happy with the absorbency on these compared to other brands that I have tried. They lasted four hours without leaks and did a good job absorbing the blood rather than it sitting on top, even with clotting/flooding.

Leakproof Comfort Brief

Store owner replied: We are so glad to hear that you had such a positive experience with the absorbency of our Leakproof Comfort Brief. It is wonderful to know they provided reliable protection and comfort during your heavier flow days. We appreciate you sharing how they compared to other brands you have tried. Thank you for your support. 🙂

Got these for me young teen & she said they are her best pair. With other pairs she was changing multiple times a day but these lasted most of the day for her! Will be getting more.

Leakproof Comfort Brief

First time user of period panties but I'm now a user for life! Very comfortable and no leaks.

Leakproof Comfort Brief

So comfortable, and cleaned up well, too. Didn't really put it to the test yet, but these are my favorite pair of period underwear so far.

Leakproof Comfort Brief

I bought lots of different brands of period underwear and Saalt is the most comfortable and pfas free. Love it.

Leakproof Comfort Brief

Store owner replied: It is so wonderful to hear that Saalt has become your most comfortable choice among the different brands you have tried.
