All of the freedom, none of the panty lines.

A little more coverage without sacrificing that second-skin feel. Barely-there shades are practically invisible under everything from workwear to lounge sets. The patented absorbent gusset keeps you dry, while super-stretchy body fabric and bonded seams deliver a second-skin fit so smooth you'll forget you're wearing anything. Luxe, four-way stretch lets you move through your day without breaking focus to fix your underwear.

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.

  • Body: 62% polyamide, 38% elastane
  • Lining: 92% recycled polyester, 8% elastane, polyurethane
  • Gusset: 100% polyester

How It Fits

  • High-rise waist with full coverage
  • 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!

  • 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!

Reviews

Leaked and messed up my pants

"I purchased mostly the heavy/heaviest flow panties and the short but unfortunately only few hours in it's leaking thru and my pants are dirty. It's no fun to wash the underwear and the pants. I had same issue with the shorts and the high rise panties."

Maryam A. (2/5)

Loose on the belly

"This is a great option for really bad cramps and if you do not want a tight waist band. . . . but its a little too loose for my liking and it moves around alot"

Jenelle (4/5)

I like their performance, received defective produ

"I committed and ordered 4 pairs of these in addition to the shorts for over night and after using them for my last 3 periods I've been really impressed with their performance. I am disappointed that after only 2 washes, being sure to follow the care instructions, one of the pairs waistband separated from the rest of the piece. I reached out via a "contact us form" over a week ago and have heard nothing back so far. They seem to be one of the more affordable brands though still a price commitment to get enough for a full period and I like that the brand is conscientious about what their product is made out of"

Tia (4/5)

Best Period underwear

"Fits super comfortably. Seamless is right; No poking or "cutting" into the waistline. Nonvisible under jeans, pants, thick leggings. No worrying about if your pad is visible or your tampon is leaking. I used it on high flow days as a back up with a disk. Normal days it absorbs and then "goes away" with no odor or wetness. I have used three other brands before and Saalt is a million times over the best."

Kristina S. (5/5)

Fabulous but run small compared to other brands

"These are so comfortable and feel barely there. Obsessed! I had not worn saalt before and typically wear a 2x in underwear (jeans 18-20) and I needed a 3x in this specific pair. All other saalt underwear I needed a 4x and the hanky panky saalt collection I wore an XL so lots of surprise sizing."

Elizabeth S. (5/5)

Between 1-star and 5-star

"I don’t know if the color makes a difference or what. I bought a black pair and a dark brown pair, both of which were to be used for bedtime. I bought and received these in February just before that month’s period. I rotated between both pairs, handwashing and hanging them to dry for the several nights I needed them. Each were fine in February. The following month, I wore the black pair overnight for the first day of my period, which is always a light flow. The next night, I wore the brown pair overnight, on the day of my medium flow, and I woke up the following morning to a stained bed sheet. This morning—now April—after my third day and after sleeping in the brown pair, I woke up to stained sheet, though less stained than last month’s. I’ve not had this issue with the black pair, so I don’t know if there’s a quality assurance issue at play with the brown pair, but the sole purpose I bought these panties for was to be able to sleep during my period and not worry about any accidents. It’s unfortunate that hasn’t happened yet."

Sara (2/5)

Terrible

"Fabric is awful. Rubbery, like the plastic pants that used to be put over cloth diapers. I never even tried them on. Put directly in donation bin. You can do better!"

Marlena B. (1/5)

Liner doesn’t come up far enough.

"I love the fit and feel of these but the liner doesn’t come up far enough in the front and i end up bleeding on my pants. I usually just wear black clothing to hide any of the stains."

Jordan W. (3/5)

Movement approved

"These are very comfortable and fit exactly the way I wanted them to. They are true to size and the liner is long enough that I’m not worried about a leak. I stay dry in them and can move all around with risking it shifting and a leak happening. These are amazing."

Michaela O. (5/5)

Comfortable

"I got size XL. I do think I should have sized down. Large is my usual size but I thought maybe a size up would make me feel good as I get so bloated. The fabric feels great but also one of those fabrics that make me feel like they will fall down. They don’t actually fall down. I think it is just a me thing. I love the absorbency of these period underwear. All their underwear that I have tried has been perfection when it comes to absorbing."
