Hey there, let’s talk about something that’s been a game-changer for so many of us navigating the messy, unpredictable, and sometimes downright awkward realities of life—leakproof underwear. Whether you’re a teen running from class to band, a mom juggling a million tasks, a postpartum warrior reclaiming your body, or someone just trying to stay active without worrying about bladder leaks, the right gear can make all the difference. We’ve been down this road, digging into the options, and today we’re pitting two heavyweights against each other: Saalt and Thinx. Both brands promise to keep you covered through period flow, discharge, and those unexpected leaks, but which one truly fits your lifestyle?

At Saalt, we’re all about empowering people—teens, moms, postpartum folks, and beyond—through every stage of life with premium leakproof underwear that doesn’t just perform but also aligns with values like sustainability and period equity. As a B-Corp, we’re committed to less waste, crafting products without harmful PFAs, and donating 1% of our revenue to impact programs worldwide. Our motto? End the panicked sprints to the bathroom and the sweaters tied around waists. We’ve got your back (and your front) with a range of absorbencies, styles, and sizes. So, let’s dive into this showdown and see how Saalt stacks up against Thinx to help you decide what’s best for your day-to-day grind.

PFAS and Fabric Safety: Digging Into the Details

Let’s peel back the curtain on something that doesn’t get nearly enough airtime in the world of leakproof and period wear: PFAS, or per- and polyfluoroalkyl substances. These are the so-called “forever chemicals” that have been used for decades to make products water- and stain-resistant. Sounds great on paper, right? Who doesn’t want underwear that laughs in the face of leaks? But here’s the rub—these chemicals don’t break down. They linger in the environment, in our bodies, and yeah, that’s as unsettling as it sounds. (EPA)

The health concerns tied to PFAS are no small potatoes. Studies have linked them to everything from hormonal disruptions to immune system issues, and while the jury’s still out on the full extent of their impact, it’s enough to make you pause before tossing just any pair of leakproof undies into your cart. Some brands have faced heat for using PFAS in their finishing processes to achieve that waterproof magic, and honestly, it’s a bit of a black box. Labels don’t always tell the whole story, and digging into a company’s supply chain can feel like you’re playing detective with no leads. (Time Magazine)

But it’s not all doom and gloom. There’s a growing push for transparency in the industry, with more folks demanding to know what’s touching their skin—and what isn’t. When you’re comparing options, it’s worth asking hard questions about how that leakproof tech is achieved. Is it a chemical coating that might raise red flags, or are there safer alternatives at play? Fabric safety isn’t just a buzzword; it’s a real factor when you’re wearing something this personal day in and day out. Look for brands that prioritize clean materials and aren’t afraid to show their work. Your body—and your peace of mind—will thank you.

Size Inclusivity: Finding the Right Fit for Every Body

Let’s talk about a core issue that often gets glossed over in the world of leakproof and period panties: fit. Not everyone’s body is the same, and yet, for far too long, the industry has leaned on a one-size-fits-most mentality that leaves many feeling overlooked. Whether you’re a teen just starting to navigate periods, a mom juggling postpartum changes, or someone managing bladder leaks as you stay active in your later years, finding underwear that fits you—not some idealized mannequin—is non-negotiable.

Good leakproof panties should feel like a second skin, not a constant reminder of compromise. We’re talking about options that span a wide range of sizes, from petite to plus, ensuring that every body type gets the coverage and comfort it deserves. It’s about recognizing that bodies change—through pregnancy, aging, or just life—and the products we rely on need to keep up. Look for brands that prioritize inclusivity, offering detailed size charts and styles that accommodate real curves, real hips, and real needs.

This isn’t just about slapping an “extended sizes” label on a product page. It’s about design that works. Think waistbands that don’t roll down, leg openings that don’t pinch, and cuts that move with you whether you’re chasing a toddler or hitting the gym. The right fit means no leaks, no worries, and no second-guessing. So, when you’re weighing your options, dig into the details—does the brand truly cater to every stage of life, or are they just paying lip service to inclusivity? Your body deserves better than a half-hearted effort.

Leakproof Tech Explained: How Each Brand Seals the Deal

Let’s break down how each brand’s leakproof tech actually works. Both brands aim to keep you dry and confident, but their methods differ, catering to various needs.

Thinx uses a multi-layer design: a moisture-wicking top layer for freshness, a super-absorbent core for leaks (from light drips to heavy flows), and a waterproof backing to lock everything in. This setup feels like regular underwear, with a little extra bulk. Many people equate security with bulk. It’s ideal for those postpartum days or unexpected leaks during busy moments.

Saalt emphasizes a patented thinner, barely-there profile. Their layered fabrics are great for a subtle fit under any outfit. Saalt tech includes anti-odor technology for extra freshness, making them perfect for active days or as a first-step option for teens or newcomers to leakproof gear. This tech is suited for light to heavy leaks with light to super absorbencies, and everyday reassurance.

Ultimately, each brand suits different needs—both for heavy-duty protection, but one with added bulk that offers an added sense of security, the other thinner for wearing under your yoga pants or as daily backup. Choosing the right one depends on your comfort level, expectations, and needs. 

Is the Saalt Cup and Disc FDA Compliant?

One thing that sets Saalt apart from other leakproof period pants brands are that they’re a one-stop shop for all sustainable period products worn inside and outside the body. Let’s get to the heart of a question that’s likely on your mind if you’re considering a menstrual cup or disc: is it safe, and does it have the official stamp of approval? When it comes to menstrual cups and discs, the FDA doesn’t “approve” them in the way you might think of drugs or medical devices. Instead, they’re regulated as Class II medical devices, which means they need to be cleared for safety and effectiveness before hitting the market.

The good news? Saalt reusable menstrual cups and reusable menstrual discs have been through the rigorous process with the FDA and are both compliant and registered. They’re made from 100% medical-grade silicone, free from toxins and harmful chemicals, ensuring that what you’re using is as safe as it gets for your body. This isn’t just marketing fluff—it’s a product designed with your health in mind, meeting the strict standards set by the FDA for intimate use. So, if safety is your concern (and let’s be real, it should be), you can rest easy knowing Saalt cups and discs have been vetted by the folks who set the bar for medical safety in the US. And Saalt is the only brand that is fully reusable, retailing menstrual cups, discs, and period underwear to help you make the switch from all disposables to all reusables. Your pocket and planet will thank you. 

Beyond clearance, the variety of designs and firmness Saalt offers prioritizes comfort and reliability, crafted to fit a wide range of bodies and needs. Whether you’re a teen just starting out with the Saalt Teen Cup or a mom navigating postpartum changes looking for a Soft Cup or Menstrual Disc, the attention to detail here means fewer worries about leaks or irritation. It’s not just about meeting standards—it’s about exceeding expectations for what a menstrual product can do for your daily life. (National Library of Medicine)

Absorbency Head-to-Head: Light Leaks to Heavy Flow

When it comes to absorbency, both contenders in this showdown have their strengths, but they cater to different needs across the spectrum of leaks and flows. For those dealing with anything from light bladder leaks or spotting to heavy flows—Saalt offers a subtle, barely-there layer of protection that feels like a well-coded stealth mechanic: invisible until you need it. Saalt’s patented gusset is the thinnest on the reusable market and can handle up to seven tampon’s or ten pads worth of liquid, making Saalt Leakproof Underwear ideal for everyday reassurance without bulk.

On the flip side, if you’re navigating the heavy flow days of your cycle or postpartum challenges, Thinx often pulls ahead with a few higher-capacity designs. Think of it as equipping a maxed-out inventory slot—some styles can absorb the equivalent of several tampons or pads, keeping you secure through long days or restless nights. Thinx tech is built for the boss battles of leakage, with layered fabrics that wick and lock in moisture, though some users report a slightly bulkier feel compared to thinner gusset options.

For those in-between moments—moderate flow or unpredictable leaks—both brands have mid-range offerings, but the devil’s in the details. One leans toward a sleeker fit with moderate protection (think 1-7 tampons’ worth), while the other sometimes sacrifices a bit of that streamlined silhouette for extra peace of mind. It’s a trade-off: do you want agility or an ironclad defense? Your lifestyle—whether you’re chasing toddlers, crushing a workout, or just trying to survive a long commute—will dictate which absorbency tier feels like the right gear for your game.

Wrapping Up: Saalt vs. Thinx—Your Lifestyle, Your Choice

Let’s cut to the chase—choosing between Saalt and Thinx isn’t just about picking a product; it’s about finding what syncs with your life. If you’re a busy mom juggling diaper changes and school runs, or a postpartum warrior navigating new leaks, Saalt’s got your back with leakproof underwear designed for every stage. From teens to active seniors dodging bladder leaks, our range of absorbencies, styles, and sizes ensures no one’s left behind.
