Super comfortable for light or non period days
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.

Cute & cozy
This one is my favorite! I would size up because they were a little snug. I normally wear a medium, and I got a large and they fit perfectly.

White jeans approved!
Very comfortable and slim-lined while also providing peace of mind. Especially while traveling in white jeans!

Very comfortable
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.

Best underwear
I’ve tried a lot of period panties and these are by far the best for everyday wear, extra protection when using tampons and for light flow days.

Better than expected!
I got these thinking they would t work well, but was I surprised! I head a light flow day and I hate using any sort of waste feminine products. Trying to go more green. I took a gamble with getting these and it paid off. I had no leaks. I was also concerned about any odd odors that naturally come with having my period. . . . there are no concerns with these.

Love them!
I bought them specifically for when I'm doing my weight training. I always wear thongs. Finding these has been amazing. On occasion when lifting I have leaks (I'm at that age) and they catch it so I don't have to worry about wet spots on my leggings.

Stellar product— will be recommending to my patients
As a physical therapist and someone with endometriosis, I am always getting asked for recommendations and thought I’d try these. I am blown away at how great these are. So comfortable and actually work.

Material is SO soft!
It fits comfortably and it’s a good fabric. I have yet to test it with my period, but I don’t know if I would trust it fully without a disc/cup, because the gusset isn’t nearly as wide as what I would’ve thought. However, it is for lighter days and I would recommend it for at the tail end of your cycle!

Not bulky, yet they hold any leaks.
I am thrilled to be able to continue wearing a thong that offers leak protection. They are great for working out. They do not move or add bulk.

These are nice for a light day and when I’m not too active. When active can tend to move around a little depending on pants

My new fave undies!!
AMAZING!! I thought I would never find a pair underwear that fits me perfectly, but these are it!! Very light, very clean feeling, and I have not had a leak yet! I experience really light periods and super inconsistent so these are perfect for me during my week!

There are much better thong's on the market. These are designed too thin, not much coverage at all.

Very comfortable fit
I've searched long and large to find menstrual underwear with a slim gusset and for light weight. These are exactly what I was looking for, they fit really well and the material is so soft!
