What Are Period Panties And How Do They Work?
Heavy flow period panties have redefined what reliable, sustainable period care can look and feel like. Designed to absorb menstrual flow directly into the fabric, they offer a comfortable, reusable alternative to pads or tampons — or a seamless backup to options like a menstrual cup or period disc. Whether worn alone or in combination, period panties provide coverage and peace of mind during every phase of your cycle.
The Technology Behind The Comfort
Saalt’s period underwear for heavy flow is built with patented gusset technology that quietly does the heavy lifting. The top layer wicks moisture away from your skin to keep you dry, while the absorbent core locks in liquid and helps neutralize odor. Beneath that, a breathable, leak-resistant barrier ensures you stay protected day or night.
Despite the tech, these garments are anything but bulky. With a sleek, body-hugging fit and soft-stretch fabrics like TENCEL Modal, they feel just like your favorite everyday underwear — only better equipped to handle heavy flow, bladder leaks, or anything in between.
A Trusted Option For Heavy Flow
For those with heavier periods, Saalt offers Super absorbency styles like the Leakproof Comfort Brief, which can replace up to 10 regular tampons or seven pads’ worth of flow. These styles are specifically engineered for high-capacity performance without compromising comfort. They’re an ideal option if you're tired of doubling up on products or setting reminders to change every few hours.
Many users also pair period panties with a menstrual disc, which sits higher in the vaginal canal and offers up to 12 hours of wear. If you’re curious about how it works, Saalt offers a supportive, step-by-step guide with visuals on how to insert a menstrual disc.
Care That Fits Your Life
Taking care of your Saalt underwear is simple: rinse after use, wash on cold (ideally in a mesh delicates laundry bag), and hang dry. It’s a low-maintenance habit that supports a low-waste lifestyle, especially when you rotate between several pairs.
And for everyday wear beyond your period, Saalt also offers moisture-wicking underwear designed to handle sweat, discharge, and light spotting with the same breathable comfort and multi-layer gusset design.
Period Care That Works For You And The Planet
Beyond their functionality, menstrual panties for heavy flow are part of a bigger movement toward sustainable care. As a certified B Corp and Plastic Negative brand, Saalt designs every product with ethical sourcing, clean materials (never using PFAS), and long-term reusability in mind. PFAS, or “forever chemicals,” are a group of synthetic substances often used in water-resistant fabrics. They're often linked to environmental buildup and potential health risks. Saalt doesn’t use them, in order to keep both your body and the planet safer.
More Than Just A Product
Choosing period panties isn’t just a practical decision; it’s a quiet act of advocacy. Every pair worn, washed, and talked about helps normalize conversations around periods and creates space for a more inclusive, stigma-free world. It’s comfort with purpose, built to support you and the next generation of period care.
Every cycle becomes a chance to reduce waste, save money, and feel good in your body without relying on disposables or sacrificing your lifestyle. Whether you’re just getting started or ready to upgrade your routine, our underwear for heavy periods offers a solution built for real life.
What To Look For In Period Panties For Heavy Flow
Choosing the right features makes all the difference if you’re looking for sturdy, leakproof underwear. Here's what to keep in mind when selecting period underwear for heavy flow that holds up:
High Absorbency, Clearly Stated
The first (and most important) feature is absorbency. Saalt’s Super absorbency period underwear replaces up to 10 regular tampons or seven pads, giving you dependable coverage through overnights, long days, or unexpected surges in flow. Look for products that clearly outline absorbency levels in tampons or milliliters, so you know exactly what you’re getting. However, keep in mind that period underwear may need to be changed more often, depending on your flow, so you might want to stock up on multiple pairs.
Leakproof Construction Where It Counts
A full-coverage gusset is key. Select styles feature Saalt’s patented gusset tech extending from front to back to minimize the risk of leaks, with thin yet powerful layers that wick, absorb, and lock in moisture. The seams are carefully designed for durability and discretion, keeping everything where it needs to be without bulk or awkward padding. We want you to be able to wear your favorite yoga pants to the gym without any pad lines in sight.
Comfortable, Flexible Fit
Heavy flow days are hard enough to manage without battling stiff seams or tight waistbands. Saalt underwear is made from soft-stretch, breathable fabrics that hug your body gently and move with you. The goal? All-day comfort that supports your flow without fighting it.
Breathability That Keeps You Feeling Fresh
Moisture-wicking top layers keep you dry, even during extended wear. Suppose you’re prone to sweating, spotting, or discharge in between cycles. In that case, Saalt also offers moisture wicking underwear designed with the same leakproof gusset and airflow-friendly fabric — no plastic-feeling textures or synthetic odors here.
Sustainable, Body-Safe Materials
With Saalt, performance doesn’t come at the expense of your health or the planet’s. All Saalt period underwear is made from clean, responsibly sourced materials, including recycled fibers and gussets made without PFAS finishes. That means no toxic coatings or “forever chemicals” touching your skin, and a lighter environmental footprint with every wash-and-wear cycle.
Made To Last (And Wash)
Durability matters. Our period panties are washer-friendly, hang-dry recommended, and built to retain their absorbency through repeated use. They’re designed to be worn again and again; no sagging, shrinking, or unraveling after just a few cycles.
Finding the best underwear for heavy periods starts with knowing what matters most: absorbency, protection, and comfort you can count on. With thoughtfully engineered products and clean sourcing, Saalt makes it easier to choose period care that feels good, works hard, and supports a more sustainable future.
Comparing Period Panties To Pads And Tampons
When managing a heavy period, comfort and reliability matter. While pads and tampons have long been go-to solutions, period panties offer a reusable alternative that many find simpler, gentler, and more sustainable. Understanding the differences can help you choose what’s right for your body and lifestyle.
Comfort And Convenience
Tampons offer discreet protection and are widely available, but they require frequent changes and may not always hold up during a heavy flow day. Pads, though non-invasive, can shift, bunch, or feel bulky, especially during exercise or overnight wear.
Period panties, by contrast, are designed to be worn like your favorite pair of underwear with no extra weight. Saalt’s Super absorbency styles can hold up to 10 regular tampons’ worth of fluid, making them a reliable choice for all-day or overnight wear. You don’t need to double up or dash to the bathroom every few hours, and you can go about your day feeling secure and supported.
Environmental Impact
Disposable pads and tampons generate billions of waste items each year, most of which contain plastic components that take centuries to break down. Their production also consumes large amounts of water and energy.
Reusable options like period panties and menstrual cups offer a lower-impact solution. A single pair of Saalt underwear can last for scores of home launderings with proper care, replacing hundreds of disposable products over its lifespan and significantly reducing your environmental footprint.
Health Considerations
Some disposable products may include fragrances, synthetic fibers, or other chemical treatments that aren't ideal for sensitive skin. Tampons also carry a small but serious risk of Toxic Shock Syndrome (TSS) when worn for extended periods.
Period panties help sidestep some of those risks by design. Our underwear is made with carefully selected, non-toxic, body-safe fabrics and does not involve internal wear, which reduces certain concerns associated with products like tampons. If you're seeking a more natural, gentle approach to period care, they offer peace of mind along with performance.
Period panties aren’t just a passing trend; they’re part of a broader shift toward menstrual care that’s safer, more sustainable, and built to support real people with real flow. For many, they’ve become an empowering upgrade from the cycle of disposables, offering a modern alternative that works just as hard as you do.
Caring For Your Period Underwear
Maintaining your Saalt underwear is simple, and it helps extend the life of your favorite pairs so they can continue doing their job cycle after cycle. With just a few thoughtful steps, you’ll keep them fresh and functional.
- Rinse After Use: Rinse your Saalt period underwear in cold water as soon as possible after wearing. This helps prevent staining and maintains the absorbent layers. Rinse until the water runs clear; no need for soaking.
- Use A Gentle Wash Cycle: Toss them into the machine on a cold delicates cycle, ideally in a mesh laundry bag to protect the fabric. Use mild, fragrance-free detergent, and skip anything harsh like bleach or stain removers. For hand washing, a gentle massage with detergent is all it takes.
- Skip Fabric Softeners: Fabric softeners can coat the fibers and interfere with absorbency, so it’s best to leave them out. Your undies will stay more effective and last longer without the residue.
- Air Dry Only: Hang dry is the way to go. Avoid the dryer; high heat can wear down the elastics and gusset tech over time. If you can, let them dry in indirect sunlight, which acts as a natural disinfectant and odor neutralizer. Placing your drying rack near a window with plenty of natural light will do the trick.
- Store In A Clean, Dry Space: Once fully dry, store your Saalt underwear in a breathable bag or drawer, away from excess heat or moisture. That way, they’re always ready when your next cycle begins.
With a little care, your period underwear will stay soft, reliable, and effective for years. It's an easy habit that supports your body and a more sustainable planet. For more specific information, check the “Care Instructions” tab on the product page of your purchased item.
