The Benefits Of Leak-Proof Underwear

Feeling secure in your period care shouldn’t be a luxury; it should be a given. With Saalt's leak proof underwear, you get protection that’s subtle, sustainable, and designed to support you through every part of your day. Here's how it makes a difference:


Peace Of Mind, All Day Long

Say goodbye to strategically tying sweaters around your waist or planning your day around bathroom breaks. Our period panties for heavy flow offer powerful absorbency in a featherlight design—built to help you stay dry during periods, workouts, and even light bladder leaks.


Subtle, Stylish, And Size-Inclusive

There’s no reason sustainable period care shouldn’t look as amazing as it feels. Saalt’s leak proof underwear comes in practical cuts, beautiful colors, and thoughtfully designed styles, so you feel great about what you’re wearing, inside and out. With a range that includes sleek bikini cuts and plus size period underwear, we offer styles that support your shape and your flow without sacrificing how you feel in them.


Comfort Without Compromise

Traditional pads and tampons can be bulky, irritating, or unreliable. Unlike traditional period and incontinence products, Saalt Wear feels just like your favorite underwear. The materials are soft, moisture-wicking, and breathable—no bulk, no crinkle. It’s why so many call it the best bladder leak underwear they’ve ever tried.


Better For The Planet (And Your Budget)

Every single-use pad or tampon tossed away adds to the growing landfill problem we all face. Switching to reusable, non-toxic period products drastically cuts down on waste and lets you care for both yourself and Mother Earth. Over time, this choice is a win for your wallet too, replacing hundreds of single-use products with one durable, reliable pair.


No PFAS Used In Manufacturing

Saalt’s period underwear made without without PFAS is carefully crafted using fabrics that are never treated with PFAS and regularly tested to meet the highest standards of safety and sustainability. PFAS (short for per- and polyfluoroalkyl substances) are synthetic chemicals often used to make products water- or stain-resistant. However, according to the Environmental Protection Agency, they can persist in the environment and have been linked to potential health concerns. That’s why we do not use any PFAS in our fabrics or finishes.


Made To Support Your Rhythm (And Real Life)

Whether you’re dealing with periods or pee leaks, you deserve better than constant worry. Saalt’s pee proof underwear is also a game-changer for light incontinence. Want to know exactly how period panties work? We’ve got you covered in the next section.


Choosing leak proof underwear isn’t just about convenience. It’s a commitment to lasting comfort, confidence, and conscious care that works for every body, every day. And with Saalt, you’re taking better care of yourself and the world around you by switching to sustainable period care.


Underwear That’s Built For Life’s Leaks

Leaks can be unpredictable. Saalt’s leak proof underwear for women is thoughtfully engineered to absorb fluid, prevent leaks, and keep you feeling dry and supported, no matter where your day takes you.


Multi-Layer Protection, Seamlessly Built In

What sets Saalt Wear apart is our patented, multi-layered gusset construction, designed to work seamlessly without bulk:


  • Top Layer: Soft and breathable, this layer wicks moisture away from your skin almost instantly, so you feel dry and comfortable.
  • Middle Layer: The absorbent core traps and holds fluid, comparable to several pads or tampons, depending on the style and absorbency level. It’s suitable for everything from light spotting to a full workday or overnight wear.
  • Bottom Layer: A leak-resistant barrier that keeps fluid from escaping, giving you peace of mind and dependable coverage.


Because of its advanced construction, Saalt Wear remains thin and flexible despite being highly absorbent, so you don’t feel like you’re wearing athletic gear. That’s what makes it ideal not just for periods, but also as bladder leak underwear, providing invisible support without compromising on comfort.


A Simpler Way To Stay Protected

Whether you need backup for internal products or a stand-alone solution, Saalt’s leakproof technology makes it easy to manage your flow without stress, single-use waste, or compromise. Better protection shouldn’t make your day more complicated—it should help you feel more free.


Find Your Fit With Leak Proof Underwear

Your period isn’t one-size-fits-all, and your protection shouldn’t be, either. The right pair of leak proof underwear adapts to your flow, your lifestyle, and how you want to feel. Saalt Wear is designed to do just that, offering a range of absorbencies and styles that meet your needs with comfort, confidence, and clean design.


Let’s break it down so you can find your perfect fit.


Start With Flow: Absorbency Levels That Flex With You

Everyone’s cycle is different. Saalt’s leak proof underwear is available in absorbency levels designed to meet you where you are—whether that’s managing period flow, discharge, or bladder leaks.


  • Zero Absorbency: Great for everyday wear when you want breathable, moisture-wicking comfort without built-in protection.
  • Light Absorbency: Ideal for spotting, light discharge, or as backup for a menstrual cup or disc.
  • Regular Absorbency: A go-to for moderate flow days or consistent spotting. Offers peace of mind and can double as bladder leak support.
  • Heavy Absorbency: Best for heavier period days, overnight wear, or postpartum needs. Designed to keep you dry longer without the bulk.
  • Super Absorbency: Our most absorbent option, made for high-flow days, hormonal shifts, recovery phases, and anyone seeking max protection with minimal effort.


Choose A Cut That Matches Your Personal Style

Once you know the absorbency level you need, pick a style that fits how you live.


  • High-Waisted Briefs: Provide full coverage and a secure feeling. A favorite for sleep, recovery, or anyone who likes extra support.
  • Bikini + Hipster Cuts: Versatile and easy to wear. These styles blend into your day, from meetings to movement to comfy nights at home.
  • Sport Shorts Or Boyshorts: Extra length and coverage, great for overnight, active days, or just lounging in comfort.
  • Thongs: Yes, really! Designed for light absorbency or cup backup without visible lines.


All Saalt Wear is made with soft fabrics that wick moisture, lock in leaks, and move with your body. Our underwear is built to be easily washed, so you always feel fresh without needing a backup pair. However, the CDC recommends regularly changing your menstrual products, so it’s a good idea to pick up a couple of pairs for consistent support throughout your entire cycle!


Make The Switch

Leak proof underwear is built to last, but how you care for it makes all the difference. Follow these easy steps to protect your underwear’s performance, comfort, and longevity:


  1. Rinse After Use: As soon as you take them off, rinse in cold water to help prevent staining. Gently squeeze out excess water—no twisting or wringing.
  2. Wash Gently: Hand wash or machine wash on cold, preferably in a mesh laundry bag. Use a mild detergent. Skip bleach, fabric softener, and ironing. They can damage the fabric and absorbent layers.
  3. Hang Dry: Air drying is key. Lay flat or hang in a well-ventilated space. Avoid the dryer—high heat can break down the elastic and gusset layers over time.
  4. Store Clean And Dry: Once dry, store your underwear like any other delicates. No special containers needed; just a clean drawer will do.


With a little care, your Saalt Wear will stay fresh, reliable, and ready to support you, cycle after cycle.
