Full-Coverage Comfort Meets Leakproof Confidence

Period underwear boyshorts are a modern classic bringing together the cozy, full-coverage silhouette you love with the leakproof power you need. Saalt’s period boyshorts offer a curve-hugging fit across the hips and booty with no shifting, bunching, or backup plans required. Whether you’re headed to bed or powering through your day, they’ve got you covered with zero wardrobe worries.


Why Boyshorts Are A Period Powerhouse

There’s a reason period panties boyshorts are a community favorite. The wider-cut design delivers breathable support and next-level comfort, especially on heavier days when you need a little extra reassurance. With their full hip and bum coverage, boyshorts help you move, lounge, or sleep with confidence without relying on pads or strings.


Here’s what our customers are loving about our Leakproof Comfort Boyshort:


  • Miranda D. says: “I wore these at the tail end of my most recent period, and they worked like magic! Kept me dry from some spotting and didn’t leak through my pants at all!”
  • Hannah O. adds: “These are SO SOFT. And they really live up to my expectations for being leakproof and odor-free. These, combined with a Saalt disc, make my periods hassle-free.”


Looking for the same protection in a different fit? Saalt’s period panties for heavy flow are available in cozy brief or low-cut bikini styles, all offering the same silky smooth fabrics you love with boosted absorbency.


Inside The Leakproof Layers: Saalt’s Patented Gusset Tech

At the heart of every pair is Saalt’s ultra-thin gusset. It’s the secret to staying dry without bulky padding or added weight. Each gusset features:


  • Moisture-Wicking Top Layer: Pulls fluid away from your skin to keep you dry and comfortable.
  • Absorbent Inner Core: Locks in liquid and odor without added bulk.
  • Leak-Resistant Bottom Barrier: Keeps everything securely contained.


This triple-layer tech is thoughtfully engineered to replace up to 6+ pads or 8+ tampons in our Super Absorbency styles. Curious to learn more? Check out our deep dive on how period panties work.


Pairing Boyshorts With Menstrual Cups

If you’re still not convinced that period underwear is enough for your heavy flow days, we understand. If you need that extra peace of mind, we suggest pairing your period underwear with a menstrual cup (like the Saalt Cup or Saalt Disc) for next-level coverage. It’s a good backup, especially if you’re still getting the hang of internal products. The breathable design supports your cup with soft, flexible security so that you can move through your day without second-guessing leaks. It’s a small switch that doubles down on comfort and sustainability.


Safe For You, Kind To The Planet

Period care should never ask you to choose between safety and performance. That’s why our period underwear is never treated with PFAS. Per- and polyfluoroalkyl substances (PFAS) are long-lasting chemicals that are present in the environment due to their widespread use. The Environmental Protection Agency states that scientific studies show that exposure to PFAS may be harmful to human health.


In response to this, Saalt’s period underwear made without PFAS is crafted using responsibly sourced materials and rigorously tested to meet the highest standards for health and sustainability. You can explore our full collection of non toxic period products designed to protect both your body and the environment.


Reusable protection means fewer trips to the store, less waste piling up in landfills, and more money saved over time. After all, one pair of period underwear can replace hundreds of disposables without sacrificing comfort or performance. So, every time you choose Saalt, you're saying yes to a cycle that’s better for your wallet, your peace of mind, and the planet. 


Fits Every Body, Supports Every Flow

At Saalt, we know that period care looks different to everyone. That’s why our boyshorts and other leakproof styles are typically available in sizes XS to 4X. Our inclusive range of plus size period underwear is designed to help you find your ideal fit, because support and comfort should never be limited by sizing.


Prefer a different cut for different days? Saalt also offers briefs, bikinis, and high-waisted styles—all made with the same signature gusset technology, all ready to support you through every cycle.


Period Boyshorts vs. Traditional Options

Period care is deeply personal, and the products we use shape how we move through our day, physically and emotionally. Traditional disposables like pads and tampons have long been seen as the default, but they often come with trade-offs: shifting, chafing, leaks, and the mental tally of how many you’ve packed for the day. They also create an environmental burden that’s rarely acknowledged.


A Smarter, More Comfortable Fit

Enter period underwear boyshorts. Designed for full-coverage comfort and next-level protection, period boyshorts from Saalt are made to support your body, not restrict it. With a mid-rise fit, breathable feel, and built-in leakproof layers, they stay put whether you’re at work, asleep, or out for a walk. No more stressing about whether your pad is in the right place. No more tampons that dry you out. Just smooth, soft protection you can trust.


A Better Choice For The Planet

According to a study available on the National Center for Biotechnology Information, the environmental impact of menstrual hygiene products is substantial, with the average person expected to use 10,000 menstrual products in their lifetime. Most contain plastic and synthetic fibers that take centuries to break down. At Saalt, we’ve found that disposable period products can generate more than 20 billion pieces of waste annually in the U.S. alone. When you make the switch to a reusable solution like a period disc or a pair of period panties, you’re diverting waste from landfills and oceans while still receiving the top-tier performance you need. Over time, you can help save thousands of single-use products from going to our landfills and cut down your monthly period care expenses.


Why It’s More Than Just A Swap

As a certified B Corp, we are committed to meaningful change. We donate 1% of revenue to fund menstrual health, education, and sustainability programs, and we’ve already helped divert 22 million+ disposable products from waste streams. So, choosing period boyshorts isn’t just about switching your product. It’s about choosing comfort that aligns with your lifestyle and values. It’s about protection you don’t have to second-guess and sustainability you can feel good about.


You’re not just investing in underwear. You’re investing in your freedom, your health, and a cleaner future. That’s the power of better period care—Saalt style.


Make The Switch

Periods can already throw so much unpredictability your way, so you deserve to have leakproof reassurance. The key to feeling your absolute best? The right fit! For instance, our Leakproof Comfort Boyshort is soft, stretchy, and thoughtfully designed to feel like a soft, stretchy hug. Here’s how to find your just-right fit in this style for comfort, confidence, and dependable coverage that lasts.


  • Stick With Your Usual Size: The Leakproof Comfort Boyshort is true to size and fits like your favorite lounge underwear. If you’re between sizes or want a more relaxed feel, consider sizing up.
  • Measure Your Waist and Hips: Use a soft tape measure to get the measurements of your waist (narrowest point) and hip (widest point). This ensures a fit that sits smoothly on your body without digging, rolling, or squeezing.
  • Full Coverage, Full Comfort: These boyshorts offer mid-rise, full-back coverage and a soft-stretch leg opening that moves with you. No wedgies. No creeping. Just dreamy-soft comfort that stays put.
  • Extended Gusset = Serious Absorbency: With extra gusset length paired with our Super Absorbency tech, this particular style can replace up to 7 pads or 10 regular tampons. That’s perfect for heavy periods, postpartum needs, or overnight wear.
  • Made From Sustainable Softness: Our Leakproof Comfort Boyshort is crafted with TENCEL™ Modal, a naturally breathable fiber from renewable beech wood. The body is made of 95% TENCEL Modal and 5% elastane for extra stretch.
  • Not Treated With PFAS: Like all Saalt Wear, this period underwear boyshort is made without PFAS and part of our commitment to skin-safe period products backed by third-party testing.
  • Easy Care, Long Wear: Rinse after use with cold water, then machine wash in a delicates bag. Skip fabric softener and the dryer to preserve the tech. Air dry for best results.

Frequently Asked Questions

At Saalt, we only use responsibly sourced, breathable, and durable fabrics. For example, our Leakproof Comfort Boyshorts are crafted from soft-stretch TENCEL™ Modal—a buttery-soft fabric made from sustainably regenerated cellulose fibers sourced from renewable beech wood. The gusset features Saalt’s thinnest, driest, and most advanced multi-layer technology to help wick moisture, trap leaks, and resist odor. Every layer is intentionally designed to support both your body and the planet.

Just like other period care products, it’s all about knowing your flow. Saalt boyshorts are built for long-lasting protection. If you're managing a heavier flow or using them overnight, you may want to change more frequently. Always listen to your body and swap out when they start to feel damp or heavy. However, the CDC recommends changing your period products regularly, because all of that trapped moisture and heat can lead to a rash or infection.

Yes! We offer a special line of period care products for teens, which includes our Leakproof Teen Sport Short. With no strings, wings, or shifting pads to manage, they offer discreet comfort and all-day support for school, sports, or sleepovers. Available in Youth S through Youth XL, they're designed to flex with growing bodies and busy lives.

With proper care, Saalt Wear can last for years. That means fewer disposables, less waste, and major savings over time—proof that sustainable period care is better for your wallet, too.

Of course! Almost all of our boyshort cut offerings come in multiple colors. You can also shop other Saalt silhouettes—like briefs, bikinis, and high-waist styles—all made with our signature leakproof gusset. Choose from everyday neutrals or limited-edition colors that match your vibe any day of the month.

Saalt boyshorts are champions on dry land, but they’re not made for the water. For pool or beach days, we recommend pairing a Saalt Cup or Saalt Disc with your favorite swimsuit for worry-free, invisible protection.
