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!

Customer Reviews
Overall rating: 4.2 / 5 from 360 reviews.
I really like the comfort and peace of mind wearing this product! Just a minor comment that last time I ordered a brief and now I ordered a bikini, and the size/format/shape is the same. I am not sure if it's a misunderstanding on my part, and that doesn't make it like less, I was just expecting a little less size on the sides. Overall, really great product and service!
Saalt was quick to send me a replacement pair when mine ripped unexpectedly on the first wear. Customer service was excellent and I'm excited to order more!
They were very soft and comfortable and no leaking when I wore them. Slight fraying after the first wash (washed cold and air dried as labeled) but overall nice!
The most comfortable thing I’ve worn. I don’t feel gross like I did in the past using pads. They’re not bulky. I bought 2 pairs just to try and never went back. I ended up buying more colors and some different styles. My period is no longer a time I fully dread because I have less cramping, and more comfort!
I am so surprised how comfortable and flattering these underwear are. I also like the freedom of not wearing a tampon on my lighter days. I would wear them on heavier days too if the leakproof absorbent portion went further up and back, as others have mentioned. I would still recommend these but might be reluctant to wear them to sleep in or on a heavy day without additional protection.
I love these so much! I've been using them for 2 years or so, and they are always my go-to pair. The fabric is super soft and comfortable. They fit well and can hold a lot before leaking. They do a really good job keeping me feeling dry. If they get pretty full, they do start to feel a little more wet, but not until then.
I wish period underwear was around when I pre-teen. . . would have spared me so many leaks. None the less I am so happy they exist. Salt's Leakproof underwear and sleep shorts have become a game changer for me!
These have been great so far! I'm not sure if they fixed the lower front gusset that some people were complaining about or not, but these were good coverage for me and the gusset felt the same or very similar to the brief. The fabric is super soft and there's a little bit of stretch, too. They kept me dry with no leaks. I bought a regular and absorbancy seemed pretty high (though I mainly use these as a backup or on light days). I definitely recommend them!

Savannah, thank you so much for sharing such a detailed review of our Leakproof Comfort Bikini. We are thrilled to hear that the fit and coverage are working well for you and that you found the TENCEL Modal fabric so soft. It is wonderful to know they have kept you feeling dry and secure as a backup. Your feedback regarding the gusset coverage is especially helpful for other customers. We truly appreciate your recommendation. 🤩👍
My main reason for going with Saalt is that they test for and intentionally do not use PFAS. I'm fairly new to period underwear and it is a bit of a miracle to me! I found the size perfectly suited to my body, and I like that I can machine wash these. So far so good on leak coverage. Will definitely buy again!
Store owner replied:
Madeleine, thank you for the fantastic review and for choosing Saalt for PFAS-conscious period care. We carefully test our materials and our Leakproof Comfort Bikini is not made with PFAS. It is great to hear the fit, leak coverage, and easy machine washing are working well for you. 🙂
If you ever want extra protection on heavy days or overnight, try the Super absorbency in the same style. And if you prefer more front coverage, the Leakproof Brief offers a wider gusset. We are thrilled you will be back for more.
I have several pairs of period underwear and my saalt ones are by far the softest most comfortable ones I own. I love how soft they are and how well they fit and honestly they feel just like non period undies. Which I for one love. I have a pair that are thicker for obvious reasons but they do tend to make me hot when I wear them. I would recommend saalt period undies to everyone looking for a period equipment alternative or back up to said equipment.
Store owner replied:
Nicole, thank you for the thoughtful review. We are thrilled that your Saalt Leakproof Comfort Bikini feels soft, comfy, and just like your regular undies 🤩.
Totally hear you on thicker pairs feeling hot. For regular flow days, our Regular absorbency is a great match, while Super is best for the heaviest days, overnight, or postpartum. That way you can choose what feels most comfortable. Your recommendation means so much to us. ❤️
i swear by these, i just bought a couple new pairs because the ones i've been using for the last couple years are finally beginning to wear out. they're well-constructed and comfy. other brands i've tried get funky real fast, these do not.
Store owner replied:
Thank you for the amazing review. It makes our day to hear your Leakproof Comfort Bikini has stayed comfy and well constructed over the years, and that they stay fresh compared to others you have tried.
We are grateful you came back for more pairs. If you ever need anything, we are here. Enjoy your new undies! 😀
Super soft, stretchy, and fits perfectly. Can’t wait to try them on my period. High hopes that they will work well based on other reviews and seeing the quality first hand.

I've experimented with Saalt and Victoria's Secret period underwear so far and love Saalt's design for my hip shape and size. I recommend washing soon after wearing for anyone who is sensitive to iron scents, though I think it's useful to remember that scents are natural during menstruation!
Store owner replied:
Katherine, thank you for the 5-star love for our Leakproof Comfort Bikini. We are thrilled the fit and design work well for your hips and size, and we appreciate your comparison with Victoria's Secret.
Your tip on washing soon after wear is spot on for anyone sensitive to iron-like scents. You are right that some scent is natural during menstruation. A quick cold-water rinse, then a prompt wash, helps keep things fresh.
We are so glad you are loving Saalt. Enjoy the comfort and confidence. ❤️
I bought a pair to try them. They work so well, I've recommended them to a few friends.
Overnight protection, for heavy flows - fully expected and wanted granny panties. These are so much vetter than that. The padding is impresively thin. No leaks. Very comfy, but on the outside, just looks like nice underwear. Must buy more.
Store owner replied:
This is amazing to hear. Thank you for sharing such thoughtful feedback on our Leakproof Comfort Bikini. It means a lot that they kept you leak free overnight on heavy-flow days and still look like regular underwear.
We designed the gusset to be thin, soft, and secure, so we are thrilled it felt comfortable and discreet. Your recommendations to friends make our day. Enjoy stocking up on your new favorites. 🤩
Feel secure during the day and have had no leakage!
