Many traditional period products are treated with chemicals you wouldn’t want near your skin, let alone rely on overnight. That’s why Saalt offers non-toxic period products, including period underwear that’s never treated with PFAS, made from rigorously tested materials that put your health first. We do not use any per- and polyfluoroalkyl substances (PFAS) in our fabrics or finishes. According to the U.S. Environmental Protection Agency, this class of synthetic chemicals may be linked to health challenges like reproductive and developmental harm, hormone disruption, and increased cancer risk.
The Hidden Waste Of Single-Use Products
But the impact goes beyond the body. A 2023 study published by the Bulletin of the World Health Organization found that single-use menstrual products are overwhelmingly made of plastic (over 90% by composition) and generate more than 200,000 metric tons of waste each year in the UK alone. Most of that waste ends up in landfills or water systems, where disposable pads can take 500–800 years to break down.
Sustainable Protection That Lasts
Saalt sleep shorts are a smarter choice for your health, your home, and your planet. Each reusable pair replaces hundreds of disposables over its lifetime, helping reduce landfill waste, microplastic pollution, and the demand for single-use resources. It's comfort that lasts, and care that extends far beyond your cycle.
Sleep Without Stress
For many of us, sleeping during our periods can feel like a tactical operation: layering towels, doubling up on products, and crossing our fingers that we won’t wake up to stained sheets. Saalt’s reusable period sleep shorts are thoughtfully engineered to eliminate that stress. Whether you rest on your back, stomach, or side, these shorts are designed to move with you and protect throughout the night. They give you back the rest you deserve—without the worry.
Serious Comfort, Zero Compromise
Saalt period sleep shorts aren’t just functional. They’re downright cozy. Think breathable, silky-soft fabrics that feel like your favorite loungewear, paired with a secure fit that stays put all night. There are no stiff edges or bunching seams to dig in or wake you up. For those who need serious absorbency, our period panties for heavy flow deliver all-night comfort without added bulk. The result? You can settle into sleep without any midnight bathroom runs. This is period protection that lets you wake up feeling refreshed, not restricted.
Built-In Leak Protection You Can Trust
At the heart of every pair of Saalt sleep shorts is our patented gusset technology. Designed with multiple ultra-thin layers, the gusset pulls moisture away from the skin and locks it into the absorbent core, keeping you dry and confidently covered throughout the night.
But this protection isn’t just about period flow. It’s about honoring every chapter of your body’s journey. Whether you’re managing overnight period leaks, light bladder leaks, or healing after childbirth, Saalt sleep shorts meet you where you are with performance that helps you rest easier. If you’ve ever felt dismissed or underserved in your most tender moments, this is your reminder: You deserve better.
Made To Fit Every Body
Comfort shouldn't have a size limit. That’s why Saalt offers an inclusive range of sizes, including plus size period underwear in most styles up to 4X, so everyone can experience leakproof confidence. Our sizing is designed to celebrate real bodies and accommodate life’s changes, from hormone shifts to postpartum recovery.Â
Whether you're navigating monthly cycles or major milestones, Saalt period sleepwear adapts to your curves while helping reduce waste with every wash and wear. It’s period care that meets you where you are, and this small shift has a big impact: less waste, more comfort, and a reminder that even the most personal care choices can be rooted in empowerment.
How Saalt's Sleep Shorts Work
Want to know how period panties work? At the core of it all is our patented, multi-layer gusset, which is specifically engineered to wick away moisture, absorb fluid, and stop leaks in their tracks. Each layer plays a crucial role: the top layer draws fluid away from the skin for a dry, breathable feel, while the middle layer absorbs the equivalent of multiple tampons or pads. A final barrier layer provides reliable, leak-resistant protection, so you can sleep without worrying about period stains on your clothes.
Boyshorts Designed For Uninterrupted Sleep
Among Saalt’s most popular overnight styles is the Leakproof Comfort Boyshort, made from buttery-soft TENCEL™ Modal. This mid-rise style offers the fullest coverage and features an extended gusset that replaces up to 6+ pads or 8+ regular tampons’ worth of flow in the Super Absorbency option. Its ultra-soft, breathable fit means no shifting, bunching, or digging in—just smooth support through every sleep cycle.
If you prefer the feel of natural cotton, the Leakproof Cotton Sleep Short is another top pick. Crafted from breathable OEKO-TEX® certified cotton and available in tea-dyed hues, this high-rise option features front-to-back gusset coverage for full protection all night long. Like the Boyshort, it offers maximum absorbency and coverage, except this style has a fully wrapped gusset that extends from the front waistband all the way to the back. The cotton body also has good anchoring with a comfortable amount of stretch, so it stays in place no matter how much you toss and turn.
Full Coverage, Zero Compromises
Despite their powerful absorbency, Saalt’s period sleep shorts remain ultra-thin with softness your body will thank you for. The gussets are built to do the heavy lifting, offering superior absorbency and breathability in every pair. They stretch and move with your body, so you can drift off and stay asleep without interruption. These shorts aren’t just a backup plan—they’re your first line of defense and often the only product you need.Â
Ready to find your perfect pair? Whether you’re drawn to the cloud-soft Comfort Boyshort or the natural breathability of the Cotton Sleep Short, Saalt makes it easy to rest easy.
How To Care For Your Saalt Sleep Shorts
There’s nothing better than slipping into bed knowing you’re protected from leaks—no towels required. Your Saalt sleep shorts will keep delivering that leakproof peace of mind cycle after cycle. Built with durable fabrics and patented gusset tech, they’re designed to last—but like any well-made essential, a little TLC goes a long way.
- Rinse First: After a restful night, rinse your sleep shorts in cool water to remove any residual blood. This helps prevent staining and prepares them for a thorough wash.
- Wash Gently: Toss them in with your regular laundry using a mild detergent. Skip the bleach and fabric softeners—they can interfere with absorbency. Wash on cold (never hot) to preserve those ultra-thin leakproof layers.
- Air Dry For Longevity: Line drying isn’t just gentle on the fabric; it’s better for the planet (and your electricity bill). Ditch the dryer when you can to extend the life of your boyshorts and reduce energy use.
- Store With Care: Fold and tuck them away in a drawer or stash them in a breathable bag for travel. They’ll be clean, dry, and ready for your next overnight shift.
Caring for your period sleep shorts is easy, and it pays off. With mindful maintenance, you’re not just protecting your comfort and confidence. You’re supporting a more sustainable cycle, one night of uninterrupted sleep at a time.
