The idea of a period thong might seem surprising, but that’s exactly why it’s worth considering! Traditional period products have often asked us to give something up: comfort, confidence, or clothing we love. Bulky pads don’t pair well with leggings. Some internal products may come with discomfort or limitations. And full-coverage options, while protective, can feel restrictive on light days.
Thong period underwear changes that narrative. With buttery-soft fabrics and a multi-layer gusset that wicks moisture and locks in leaks, our period proof thong is made to look and feel invisible. Whether you're hitting the gym or heading out in a fitted dress, this style lets you show up as yourself, every day of the month.
Comfort, Confidence & Conscious Design
What makes a period panties thong truly empowering is the freedom it gives back. You can wear the clothes you want—bodycon dresses, yoga sets, or high-rise jeans—without worrying about panty lines or awkward shifting. Plus, you're investing in something built to last by replacing single-use products. From light spotting to cup backup, this thong brings big impact in a small, seamless package.
Better yet, our period thongs are part of our commitment to non-toxic period products. We do not use any PFAS in our fabrics or finishes, and all products are regularly tested for safety and sustainability. PFAS (per- and polyfluoroalkyl substances) are sometimes called “forever chemicals” because they can build up in the body and environment over time. According to the Environmental Protection Agency, they’ve been linked to potential health and environmental risks. By choosing period underwear without PFAS, you're protecting your body and making a healthier choice for the planet, too.
Who Period Thong Underwear Is Made For
Saalt’s period thong underwear is a great option for:
- Spotting or Light Flow Days: When you don’t need full absorbency but still want coverage and peace of mind.
- Backup Protection: Perfect with a Saalt Cup or Saalt Disc, especially when you’re on the move or in a long meeting.
- Workout & Athleisure Outfits: Invisible under leggings or compression wear.
- Everyday Confidence: Ideal for those who want protection that doesn’t sacrifice style.
If you’ve ever thought your period limited your wardrobe or freedom, a leakproof thong is the small but powerful shift that proves otherwise. Because period care should work around you, not the other way around.
The Technology Behind Period Thongs
Period thong underwear might sound too good to be true, but it’s not! Ever wondered how period panties work? It’s the result of thoughtful design and patented, high-performance innovation that gives you freedom without sacrificing protection.
Thoughtful Layers, Targeted Protection
The gusset of Saalt’s thong period underwear features our signature multi-layer construction, made to wick away moisture, absorb leaks, and block anything from getting through. The top layer pulls fluid away from your skin for a dry, breathable feel. Beneath that, an absorbent core locks in moisture, while a leak-resistant layer adds reliable backup. It’s engineered to offer just the right level of protection for light days, spotting, or period-safe date nights.
A Barely-There Fit, Made To Move
Saalt’s period thong underwear is designed to disappear under your clothes, so you can focus on living, not adjusting. The sleek, mid-rise silhouette hugs your body like a second skin. For example, our Leakproof Seamless Thong style uses LYCRA® XTRA LIFE™: an ultra-durable, high-stretch fabric that holds its shape, resists wear, and stays silky-smooth through each cycle. Whether you’re sweating through spin class, heading to brunch, or dancing ‘til midnight, this is comfort and freedom without panty lines.
This style uses our thinnest and driest gusset yet, featuring a multi-layered, moisture-wicking core that absorbs light flow, discharge, and sweat, while staying breathable and dry against your skin. Machine washable, ultra-stretchy, and made to move. This is leakproof technology redefined for real life.
Sustainable Period Care With Reusable Thongs
There’s something revolutionary about choosing a period thong that works with your body and the planet. Every time you reach for thong period underwear instead of a disposable pad or liner, you’re making a conscious shift away from plastic-heavy, single-use waste and toward a smarter, cleaner cycle.
A Better Choice For The Earth
Unlike disposable products that are used once and tossed, Saalt’s leakproof period thongs are built to be washed and reused, helping to reduce the thousands of pads and tampons most people use in a lifetime. Fewer items in the trash means less impact on landfills and oceans, and more alignment with your eco-friendly values. Saalt underwear is also never treated with PFAS and is regularly tested for safety and sustainability. That’s what we call a win-win!
A Smarter Long-Term Investment
Period panties aren’t just convenient; they’re cost-effective. With proper care, one pair can last for years, replacing countless boxes of disposable products. That adds up to fewer trips to the store, less packaging waste, and real savings over time.
Sustainable Without Sacrificing Style
Every pair is made with durable fabrics and absorbent gusset technology that keeps you dry and protected without compromising your outfit. Whether you're looking for seamless styles like our thong or more coverage from our period panties for heavy flow, we’ve designed leakproof options to support every flow and lifestyle.

Make The Switch
Taking care of your thong is easy, and it helps extend the life of your underwear while reducing waste along the way.
- Rinse After Wear: After each use, rinse in cold water until the water runs clear. This helps prevent staining and keeps the absorbent layers working their best.
- Machine Wash On Cold: Use a gentle cycle with mild detergent. Skip fabric softener, bleach, and ironing. They can interfere with absorbency and wear down the tech.
- Use A Laundry Bag (Optional): A mesh delicates bag offers added protection in the wash. This isn’t mandatory, but it can help keep your undies on your booty for longer.
- Hang to Dry: Air drying helps preserve the fabric and fit. Avoid dryers, as heat can break down elastic and performance layers over time.
- Store Dry And Clean: Keep your thongs in a breathable space between wears for optimal freshness.
A little care goes a long way. With each rinse and wash, you’re not just maintaining comfort; you’re supporting your body and the planet, one cycle at a time.
