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!

These are very comfy and TTS

Perfect for everyday wear

These are all I wear. The most comfortable option I've found in a thong style.

Love my saalt wear. Perfect for light/end of flow days. Pretty and comfortable helps you get back to feeling normal again.

Love my saalt wear. Perfect for light/end of flow days. Pretty and comfortable helps you get back to feeling normal again.

Love this for back up protection on heavier days. Also great for beginning/end of my period. I love how it doesn't look bulky and keeps me feeling cute. I'll be getting a couple more pairs

I really love these and I am planning on getting more! They are great quality even for days you don't have your period.

Amazing. So soft and comfortable, forgot I was wearing them!

I am a 51 year old menopausal aerial dancer who has had one vaginal delivery and sometimes I leak urine when dancing. This thong has been a lifesaver. No more darting to the bathroom in the middle of class (or performing) because I am worried that I have peed. Thank you so much for creating this amazing product. PS I tried the mesh and seamless versions of the thong which did not work as well because of fit and Saalt was amazing at giving me a refund even though they had been worn.

Loved these! Effective and actually felt sexy! Would highly recommend!

Very light to pack and handles the basics. More comfortable than their other things in my opinion as it is thin and soft in back.

Love love love! These are amazing

When it comes to period underwear Saalt brand is the way to go. I've tried others and while they worked for being leak free the other brands haven't developed a product that leaves you feeling fresh. Somehow these panties keep you feeling dry and fresh while others make you feel stuffy with no air flow. I do feel they are a little over priced but I try to find them on sale. Also with these specific ones I bought a large (after reading reviews) and they fit perfectly. I usually wear a medium in underwear and a size 4 in pants.

My daily wear item! When you are of a certain age, sometimes when you sneeze, you might have a little dribble. These keep me comfortable, protected, and not adding to a landfill with liners.

I do think the thongs run small because I usually wear a S, but the M is very snug. I recall this is stated on their product description, so I appreciate them adding that as I can see myself returning/exchanging the S as that's what I would've gotten. Fits well, doesn't even feel like period underwear with how thin the absorbent area is. My flow is so light, I've never had leaks, I do think Saalt Wear can definitely stand up to heavier flows but can't speak to that personally.

Love, love, love! I'll be buying more of these cute and comfy panties!

Shocked. So good! So comfy; works well. Will definitely be purchasing more!

Thin profile, solid fit, lace is even so soft. I'm usually not one to like lace but these are so soft and comfy I don't even feel like I'm wearing lace.

These are the greatest leakproof panties out there. They are not built like others. Fit very well and I love the seamless!

Have bought other period underwear brands in the past but Saalt is WAY higher quality, love their rewards program and overall the underwear are just way softer and more absorbent than other brands

Wasn’t sure how this was going to work out. No leaks but I was also wearing my cup. Comfortable

This is comfortable and leakproof, yet still lets me feel confident!

I’m not much of a thong girlie but we’re comfortable and works in a pinch if you are spotting

Works well

Amazing thongs! They are super soft and comfy! They absorb quite a bit, but I wear them on light days.

Love this one too! It works! No more panty liners! Keep dry down there even when hiking all day! Now we need this dry liner material in the bottom band of a bra to absorb boob sweat (swoob). Please create this! I will buy it@

Great period panties! I've used another brand before Saalt and they were much thicker and less comfortable in the gusset. Saalt manages to actually still be close to my 'barely there' regular panties/thongs under clothes, even workout leggings, without bunching or riding up uncomfortably. I listened to the other reviews and sized up in this style - they fit approximately the same as the size medium panties from the Light Day Medium 3-pack.

Super cute and I like that they provide some absorption power as well. Definitely for very light flow days

I started my period when I was a bridesmaid wearing a champagne dress. These were comfy and discreet and I didn't have to worry about leaking!

Love this product and makes me feel more comfortable as I get used to using the Saalt cup.

I move around a lot during my workday and so I needed a period undergarments that work...No gaps, no stiff fabric that chafes, and especially NO LEAKS. The Saalt thong performs. I use a period cup that needs a backup system (because I have had two kids vaginally). So happy with these and side note also great for those impromptu sneezes or fast moves that create a bladder surprise too.

Super cute color and cut
