When you’ve spent years trying to make standard period products work for a body they weren’t designed for, it’s easy to feel like you’re the one who needs to adjust. But you’re not. If you’re looking for plus size period underwear, your basic needs (comfort, coverage, and actual leak protection) deserve to be met.
Leak Protection That Keeps Up With You
That’s exactly why more people are making the switch to reusable options that offer thoughtful design from the start. Period panties are no longer one-size-fits-some. Today’s best styles, like Saalt’s Leakproof Comfort Brief, are built with full-coverage fits, high-stretch fabrics, and absorbency levels that actually hold up. We’re talking up to 7 pads or 10 regular tampons’ worth of protection without the bulk or stiffness of traditional period care.
Lighter Days Still Deserve Comfort
Even for lighter days, a style like the Seamless Thong brings something most plus size menstrual underwear doesn’t: style! With its second-skin fit and silky-smooth texture, it’s proof that functional can still be beautiful, and that you don’t have to settle for bulky, beige basics just because you happen to wear a larger size. This is underwear you want to wear, not just something you reach for when you have to.
It offers just the right amount of backup for spotting, discharge, or light flow days; perfect when you want peace of mind without sacrificing how you feel in your skin. The fit is soft against the body, and designed to move with you, because comfort should never mean wearing what doesn’t speak to you.
Reusable, Without The Hassle
And if you're new to this world or wondering how reusable products fit into your routine, don’t worry. Our period underwear is designed to feel just like regular panties, only better. Most users find that a quick rinse and a cold machine (or hand) wash does the trick. Afterwards, hang them to dry — it’s energy efficient and free. The maintenance is minimal, and the payoff is major.
Ultimately, period care should be about feeling good in your body, not working around your products. And that starts with underwear that was made for you.
Leakproof Period Care With An Inclusive Range
In the world of period care, finding underwear that actually fits — in both size and function — can feel surprisingly difficult. That’s why Saalt’s plus size leakproof underwear is intentionally designed to offer real protection without compromising comfort or confidence. With absorbency levels that can replace up to 10 regular tampons of flow and styles that feel like your favorite everyday underwear, our collection makes leakproof support feel like second nature.
Comfort You Can Count On, All Day Long
Made with body-hugging fabrics, each pair is built to handle heavy days, overnights, or even bladder leaks without the extra weight. The fabric is breathable, machine washable, and never treated with PFAS: synthetic “forever chemicals” often used in water- and stain-resistant clothing, but linked to environmental and health concerns. With rigorously selected, body-safe materials choices from fabric to finish, Saalt ensures a safer, more sustainable choice for your body and the planet. Whether you're navigating errands, work, or simply relaxing at home, these styles are crafted to move with you and keep you dry.
For lighter days or a sleeker silhouette, you can also explore our moisture wicking underwear, designed for everyday wear with backup built in.
Confidence That Goes Beyond Absorbency
Plus size styles like our Leakproof Mesh Bikini and our Leakproof Lace High Waist prove that performance and style don’t have to be mutually exclusive. The Mesh Bikini, in particular, offers a refreshing departure from the basic feel of most plus size period underwear, delivering reliable protection in a silky smooth mesh design that actually makes you feel good getting dressed. Low-cut and flattering, it’s a reminder that period care can (and should) feel personal, beautiful, and yours.
A Flexible Routine That Works With You
Many Saalt users combine underwear with a menstrual cup or period disc to create a customized routine that offers backup and peace of mind on heavier days or during long hours away from home. And if you’re curious about trying a disc but unsure where to begin, Saalt offers a clear, step-by-step guide on how to insert a menstrual disc — no guesswork required.
Made For Real Life, Backed By Real Support
Life doesn’t pause for your period, and your products shouldn’t slow you down either. With Saalt’s inclusive sizing, easy-care instructions, and the Saalt Bliss Guarantee, support doesn’t stop at the product. From fit advice to first-time user tips, we’re here to help you feel confident on your terms.
Finding Your Perfect Fit: A Guide To Plus Size Period Underwear
Navigating the world of period underwear can feel like a lot, especially when you're looking for options that truly fit and perform in plus sizes. But finding the right pair isn’t just possible; it can be empowering. With the right info and a little patience, you can build a wardrobe that’s more comfortable, sustainable, and suited to your body.
Start With Your Measurements, Not The Size Label
Sizing can vary from brand to brand, so it’s worth taking a few minutes to measure your waist and hips. Use those numbers to consult each brand’s size chart (Saalt offers sizes up to 4X). If you’re between sizes, don’t hesitate to order a couple of different sizes to experiment and find your best fit. A properly sized pair should sit snugly without pinching, rolling, or cutting into your skin.
Match Absorbency To Your Flow
Every body — and every period — is different. Some need heavy coverage every day, while others experience spotting, discharge, or light flow that fluctuates throughout the week. Look for clearly labeled absorbency levels like Saalt’s Super absorbency styles, which replace 6+ pads or 8+ regular tampons, perfect for overnights or high-flow days.
On lighter days, you might reach for something lighter and sexier, like the Lace Thong. It’s perfect for date nights while offering discreet protection for your peace of mind.
Prioritize Comfort That Lasts All Day
The best period underwear feels like underwear, not gear. Look for fabrics like TENCEL Modal (used in Saalt’s Leakproof Comfort Brief), which is known for its dreamy softness, breathability, and flexibility. It moves with you, doesn’t bunch or restrict, and is machine washable for easy care.
Style Is Part Of Self-Care, Too
Although many people reserve a special place in the back of their drawer for their period underwear, that shouldn’t be the case. From sleek high-rise briefs to lace-trimmed cuts, the best plus size options let you feel confident, not covered up. It’s about choosing styles that match your preferences, reflect your personality, and help you feel at home in your body.
By focusing on sizing, absorbency, comfort, and personal style, you can find plus size menstrual underwear that supports your cycle and celebrates your body. You deserve products that feel good, work well, and meet you where you are. And once you find the right fit, the difference speaks for itself.
Sustainable Period Care That Fits Your Life And The Planet
When it comes to period care, your choices matter. Not just for your comfort, but for your wallet and the world around you. Reusable options like Saalt’s plus size period underwear offer more than just a reliable solution for your cycle — they’re part of a more sustainable, empowering way to care for yourself and the planet.
Wear, Wash, Save
Disposable products require a constant restock, but high-quality reusables can last for years with proper care. That means fewer last-minute drugstore runs and more money saved over time. One super absorbent pair can replace up to 10 regular tampons per wear, and when you rotate a few pairs throughout your cycle, the savings really add up.
Waste Less, Live More
The environmental impact of period waste is significant: billions of disposable pads and tampons head to landfills every year, many of them wrapped in plastic and made with synthetic materials that take centuries to break down. Reusable period care flips that script. With Saalt, you’re making a simple swap that drastically reduces waste.
Our styles are washer-friendly, breathable, and meant to last. We chose materials that perform well and have clean, ethical origins. That includes fabrics like TENCEL Modal, a sustainably regenerated cellulose fiber derived from renewable beech wood. These recycled fibers help minimize environmental impact from the start.
A Mission That Goes Beyond The Product
Saalt’s commitment to sustainability doesn’t stop at the product level. As a certified B Corporation and Plastic Negative company, Saalt donates 1% of revenue to support global initiatives in menstrual health, girls’ education, and environmental sustainability. That includes donating period cups and underwear to underserved communities and removing twice as much plastic from the environment as is produced in our supply chain. When you choose reusables, you're not just reducing your own waste; you’re part of a much bigger impact.
Better For You. Better For The Planet. Built To Last.
Most importantly, you don’t have to compromise to make this change. Saalt’s period underwear is designed for real life, offering the same (or better) protection as disposables. Our soft, body-hugging fabrics and patented gusset technology keep you dry without the bulk.
Whether you’re searching for everyday period underwear, a menstrual cup for added support, or exploring other low-waste options like the Saalt Menstrual Disc, your choices matter. And they can start with something as simple as a better pair of underwear.
