Made with super stretchy fabric and smooth bonded seams for a second-skin fit
Not treated with PFAS
Thinnest and driest gusset technology
Machine washable
Slip into any outfit without rethinking your underwear.
This is the pair you put on and then promptly forget about. The one that lets you pull on leggings and skip the half-squat mirror check. Sleek, super-stretchy fabric and bonded edges create a smooth, second-skin feel that moves with you. Finished in barely-there nude shades that blend beautifully. The patented thinnest and driest gusset delivers light protection for light period leaks, discharge, and sweat, without bulk or stiffness.
Fabric
Sleek, super-stretchy body fabric gives you all the freedom with none of the panty lines. Made with 4-way stretch fabric and luxe bonded seams that move with you. Second-skin fit glides so smoothly, you'll forget you're wearing anything.
Seamless body fabric is ultra-stretchy and hugs the body. It's great for those who want no VPL under even the tightest-fitting clothing, or for those who prefer stretch that accommodates body changes. If you're between sizes, consider sizing down for the best fit.

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!

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.

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: 4.5 / 5 from 310 reviews.
They were very helpful in a situation where I was concerned about a panty line.
I love the color! Super comfortable and is great on light days at the end of my cycle or as backup on have days. I felt the sizing was cut big so I would size down next time
I can’t get over how absorbent these are! The colors are adorable and I feel like I need to get every color that they have. I love how stretchy these are and you really can’t tell when I’m wearing them even if I have tight leggings on. These are a 10 out of 10 for me.
I wasn’t sure what to expect, the Saalt leakproof seamless thong surprised me tho in the best way!!The fabric is super soft, stretchy and very comfortable! I love the ultra thin gusset too! It feels so much less bulkier than I anticipated! I like too how seamless it is under clothing, no panty lines, even under my leggings!! Compared to using liners, I found them simple and very comfortable to wear. They're AMAZING and feel like underwear but give me an extra peace of mind! Thanks Saalt! <3
This underwear is great quality and can be worn under any material of clothing. I love the nude and neutral colors that can blend with any skin tone and especially the fact that it is leakproof.
I am very excited to find a period underwear that is not bulky and even better its seamless. Several of my dresses and work pants are difficult to wear during my cycle and I don’t want unsightly panty lines. This thong fits well and gives me good protection throughout the day. I will be pairing it with a tampon on a heavy day but overall it’s working great.
These are my favorite daily wears - the new brighter colors are super fun, but the seamless comfort and any "wetness" - sweat, discharge, cup leaks (which I haven't ACTUALLY experienced but still get anxious about), whatever - is handled and doesn't create any discomfort. They disappear under everything and are my new go to - have them in nearly every color!
This is such a wonderful company and products! They are environmentally conscious and truly care for women. Not only are these so comfortable but they have changed my period every single month! I will definitely be purchasing more!
I absolutely love these leakproof period panties by SAALT. I use the period cup every month but am SO EXCITED for these panties! Sometimes our bodies just need a break! There are different styles and colors of panties. I love that when one pair is purchased, one is also donated to a woman in need! Love the thought behind all of it. Highly recommend 10/10!!
It blew me away by solving the two biggest issues I usually have with period thongs: bulkiness and obvious panty lines. The four-way stretch fabric feels weightless and silky, almost like wearing nothing, and the bonded seams really do stay 100% invisible even under my tightest workout leggings or thin dresses. What sets it apart for light days or backup is how remarkably ultra-thin and dry the gusset is, unlike traditional liners that can shift, bunch up, or feel restrictive.
I tried this model in a more full coverage and needed to size down. I was looking for options wearing with medical Neuro20 EMS suit (since the pads go on the glutes and shouldn't be covered by fabric) and CEAN lymphatic shorts.

We are so glad to hear that the Leakproof Seamless Thong is working well for you! It is wonderful to know that you find them effective, even if the style is a bit different from the lacy options you have tried.
Thank you for sharing your experience and for being part of the Saalt community. Your feedback helps others find the right fit for their needs. 🙂🎉
wish the material was a little softer, but the function is incredible and the slightly stiffer material does help these to stay put all day. Should clarify that these are not uncomfortable, but just slightly less soft - I'd buy these again and they pair so well with cup or disc!

Thank you so much for taking the time to share such a detailed review of the Leakproof Seamless Thong! It is wonderful to hear that the function has been incredible for you and that they pair so well with your cup or disc. 🤩
We appreciate your feedback regarding the material. It is great to know that the slightly stiffer feel helps them stay perfectly in place all day without being uncomfortable. Your insights are truly helpful to our team and other customers. ❤️
We are so glad you found a pair that lets you move with confidence. Happy leaking! 👍
i almost only wear thongs and i love these! kept me dry on the day i was coming off my period!
These are so comfortable and flattering I'd wear them when not on my period. They would be good for sweaty gym days when you want something that won't show under your leggings. That said, I would only wear them as backup to other methods during my period. They fit more snug than other saalt underwear. For example the S fits me in these but I would wear a XS in most other saalt styles.
I had given up on wearing thongs because of my minor incontinence issues but these thongs are so comfortable and make me feel confident I won't have any embarrassing leaks.
