Leakproof underwear is a reusable, sustainable alternative for managing period flow and light bladder leaks without pads or liners. These protective underwear styles combine breathable comfort with advanced absorbent layers that move with your body throughout the day. Each pair is carefully engineered to wick moisture away from the skin, lock in leaks, and prevent spills before they happen.
The secret lies in the construction. Inside every pair, a soft, quick-drying layer pulls moisture into a thin absorbent core, while a built-in barrier keeps liquid from reaching your clothes. The result is leak resistant panties that feel as smooth and flexible as your favorite everyday pair, with no need for backup products.
Designed for comfort and confidence across life stages, leakproof underwear supports everything from first periods to postpartum recovery, perimenopause, and beyond. With breathable, body-safe materials, this is period care that simplifies routines and helps you feel naturally secure wherever the day leads.

How Saalt’s Leakproof Underwear Technology Works
At Saalt, our leakproof underwear is built around a simple idea: sustainable comfort that performs as well as it feels. Each pair blends body-safe materials with smart design to keep you dry, confident, and comfortable through every cycle. Here’s how our patented technology works layer by layer:
- Moisture-Wicking Top Layer: This soft inner layer sits closest to your skin and immediately draws fluid downward. It keeps moisture away from your body, helping you stay dry during periods, workouts, or light bladder leaks.
- Absorbent Core: The middle layer quietly handles the heavy lifting. It locks in liquid, holding several times its weight without feeling bulky. This core is what gives our protective underwear its reliable performance throughout your day or overnight rest.
- Leak-Resistant Barrier: Beneath the absorbent core, an ultra-thin barrier adds a final layer of protection. It prevents leaks from escaping onto clothing while remaining breathable, flexible, and lightweight.
- Silky, Sustainable Outer Fabric: The outermost layer feels like your favorite pair of underwear. Made with biodegradable, natural fibers, this outer fabric gives your skin room to breathe while keeping everything discreet and comfortable.
Picking the Right Absorbency Level For You
Finding the best leakproof underwear starts with understanding your body’s needs. Periods look different for everyone; some of us wake up knowing we’ll need maximum absorbency all day, while others are looking for a subtle layer of backup on lighter days or beyond. Most comfortable period underwear comes in light, moderate, and high-absorbency designs. Here’s how to figure out where you fit:
- Light Absorbency: Perfect for the start or end of your cycle, spotting, or as gentle back-up when using a menstrual cup or disc. If you want to feel confident on days when leaks catch you off guard, lightweight styles provide subtle, breathable protection.
- Moderate Absorbency: Perfect for most daily needs, this level offers enough coverage for those who experience a steady flow. It’s a go-to choice for people who want an extra layer of assurance.
- Heavy Absorbency: Designed for heavy flow, overnight wear, or those days when you need serious backup. These options use innovative, layered technology to lock in leaks and moisture, so you can focus on living your life, not your pad changes.
- Super Absorbency: Designed for the most demanding moments, from heaviest-flow days and overnights to postpartum care and bladder leaks, with a powerful hold equivalent to 8+ tampons or 6+ pads for calm, secure coverage when your body needs it.
Remember, no two cycles are the same, and a single period can shift from light to heavy, and back again, in a matter of days. That’s why many people choose a mix of absorbency levels, matching their underwear to their unique rhythm. Choose what makes you feel empowered, whether that means prepping with high-capacity options during hormonal changes, navigating post-surgery surprises, or simply planning for peace of mind.
Caring for Your Leakproof Underwear
Taking care of your leakproof underwear is about embracing habits that keep you comfortable and confident while protecting the life of your period gear, and, by extension, our planet. With the right habits, your underwear will continue feeling soft, fresh, and ready for every cycle. Here’s how to keep your absorbent underwear in its best shape:
Step 1: Rinse After Each Use
Right after wearing, give your underwear a quick rinse with cold water. This simple step helps prevent buildup and keeps the absorbent core working efficiently. A quick rinse also makes washing easier later and maintains that reliable leak protection over time.
Step 2: Wash Gently
Machine wash your underwear on a cold, gentle cycle or hand wash with mild detergent. Skip fabric softeners, bleach, and harsh chemicals, as these can wear down technical fibers and shorten the life of your underwear. For extra care, place your pairs in a mesh laundry bag to protect the delicate layers during washing.
Step 3: Air Dry Only
Heat can damage elastic fibers and affect how the absorbent layers perform. Lay your underwear flat or hang it to air dry instead of using a dryer. This one small choice keeps your underwear performing at its best while saving energy and reducing environmental impact.
Step 4: Skip Soaking
There’s no need for overnight soaking or complicated cleaning routines. Modern leakproof fabrics are designed to rinse clean easily. A quick cold-water rinse followed by a gentle wash prepares them for your next cycle.
Step 5: Handle Stains Carefully
Blood stains are natural, and treating them shouldn’t feel like a chore. Therefore, use a mild stain remover or gentle soap on lingering marks before washing. This keeps your underwear looking and feeling fresh without damaging the fibers or absorbent layers.
By caring for your leakproof pairs with these small, sustainable steps, you’re helping preserve the quality of your underwear and reducing waste with every wear.

Breathability and Odor Control Explained
Comfort during your cycle begins with breathability and odor control. Our leakproof underwear is designed to keep air flowing freely while managing moisture efficiently, so your skin stays dry and comfortable all day. Every pair uses high-performance layers that move with you, wicking moisture away from the body and reducing that sticky, heavy feeling that can come with traditional products.
At the core of this innovation is our patented gusset technology. The top layer quickly pulls moisture downward, while the absorbent core locks it in, keeping the surface soft and dry against your skin. This design limits the conditions where odor-causing bacteria can thrive, giving you freshness that lasts from morning meetings to evening rest. Each piece is made with breathable, body-safe fabrics that feel light and flexible, maintaining natural airflow without trapping heat.
Instead of masking smells, the materials work to minimize them at the source, drawing fluids into the absorbent underwear core, sealing them away, and allowing your skin to breathe. That’s what sets Saalt apart: sustainable design that feels invisible in your day-to-day life. For those seeking all-day ease, explore our comfortable period underwear, a soft, adaptable choice for feeling fresh and confident no matter what the day brings.
