Key Takeaways:
- What Makes Period Underwear Different: Saalt period underwear combines thoughtful design with body-safe materials to absorb flow, wick moisture, and prevent leaks without compromising comfort. Each pair replaces disposable products with a reusable, breathable option that respects both your body and the planet.
- Finding Your Perfect Fit and Style: Everybody moves differently, which means finding the right fit matters. From seamless period underwear for workouts to cotton period underwear for rest, each style and absorbency level is designed to match your lifestyle and flow.
- Pairing Period Underwear with Cups or Discs: Wearing period underwear with a menstrual cup or disc creates a balanced system for heavy flow days. This combination provides internal collection and external protection, offering reassurance through long shifts, workouts, or overnight rest.
Let’s talk about reshaping the period care story. For generations, we’ve been handed single-use pads and tampons, whispered advice behind closed doors, and learned to improvise with sweaters or anxious bathroom runs whenever our period appeared. That’s where period underwear steps in and quietly redefines what comfort looks like. For anyone curious about how to use period underwear the right way, this guide is here to help you begin.
Some reach for reusables to reduce waste; others turn to them after hormonal changes, postpartum recovery, or medical shifts that call for something gentler. Whatever your reason, using period underwear lets you move through your cycle with steady assurance and less stress. At Saalt, our team designs menstrual underwear to meet every flow and every stage of life. We believe in care that moves with you and is rooted in the belief that comfort should never be complicated.
What Makes Period Underwear Different from Regular Undies
For many people, switching to period underwear reshapes how they experience their cycle. Regular underwear focuses on comfort and style, while period underwear brings function and protection into the same design. Our team created Saalt Wear to feel like your favorite pair of undies while quietly handling what your body needs each day. Each style features patented technology that keeps moisture away from your skin, locks fluid securely inside, and allows airflow that helps your body breathe.
The Built-In Layers That Redefine Protection
Every pair of menstrual underwear includes an absorbent gusset, the area that sits against your perineal region. This is where protection starts. A soft, moisture-wicking top layer draws fluid away from your skin, while the absorbent core captures and holds it. A breathable, leak-resistant barrier underneath prevents transfer onto clothing or bedding.
These layers work in harmony so you can wear period underwear on its own or as backup with a cup or disc. Because period underwear provides external protection, it reduces the concern of toxic shock syndrome sometimes associated with internal products.Reusable design and simple washing make Saalt period underwear an easy, sustainable choice for anyone looking to reduce waste while staying comfortable.
A Commitment to Safer Materials and Designs
Many brands still rely on fabrics treated with PFAS (per- and polyfluoroalkyl substances), which are known for their persistence in the environment. However, our team follows a different standard. We never use any PFAS in our fabrics or finishes, and there’s no PFAS used in manufacturing for either our period-proof or non-period underwear collections, making every material we use body-safe, breathable, and perfect for sensitive skin.
How Our Leakproof Layers Actually Work and How to Wear Them
Every pair of Saalt period underwear is built to move with your body. Each layer plays a role in absorbing, protecting, and keeping you dry through every part of your cycle.
How the Layers Work Beneath the Surface
Each pair of menstrual underwear features a multi-layer gusset that quietly handles your flow. The top layer wicks moisture away from your skin, the inner layer absorbs and locks fluid in place, and the final barrier prevents leaks. This design creates reliable comfort and protection, whether you’re resting, exercising, or going through a busy day.
Since this protection is external, period underwear reduces the concern of toxic shock syndrome, sometimes associated with internal menstrual products. However, our leakproof panties use the same leakproof technology across all styles, with absorbency levels that match your needs. The seamless period underwear works best for movement and workouts, while the Comfort Collection supports rest after a long day on the job. At the end of the day, each style retains its soft texture even after many washes.
Finding the Absorbency That Goes With Your Flow
Every cycle has its own rhythm, and our absorbency options are designed to adapt to yours. Here’s how each level works:
- Super Absorbency holds about 8+ tampons or 6+ pads worth of flow and works best for heavy days, overnight wear, postpartum recovery, and light bladder leaks.
- Heavy Absorbency holds around 4 tampons or 3 pads, offering protection for long days, overnight comfort, or moderate bladder leaks.
- Regular Absorbency holds up to 3 tampons or 2 pads, making it dependable for steady flow, daily wear, and as backup with a cup or disc.
- Light Absorbency holds about 2 light tampons or 1 liner, giving gentle protection for spotting, discharge, or lighter days.
- Zero Absorbency has no gusset layers and suits non-period days when breathability and comfort matter most.
You can pair absorbencies with specific styles to suit your routine. For instance, bladder leak underwear adds extra security during postpartum recovery or mild incontinence, while workout underwear stays flexible and dry during movement. And the best is that each pair is washable and reusable, so you can care for your body and the planet.
Finding Your Perfect Fit and Style
Comfort starts with finding period underwear that works with your body and lifestyle, not against them. Just like we all have preferences for jeans or shoes, our bodies and cycles deserve choices that feel just right. Our team designed each piece of Saalt period underwear to adapt to your flow, your shape, and your day.
Exploring Styles That Match Your Routine
Each cut and fabric brings a different kind of comfort to your cycle. For those who live in leggings, seamless period underwear keeps you supported through movement without visible lines. The smooth, stretchy material feels lightweight and breathable, making it a favorite for workouts and active days.
For slower mornings or relaxed evenings, cotton period underwear surrounds you in softness that feels familiar and calming. The natural fibers let your skin breathe while maintaining reliable leakproof protection. For more refined moments, lace and mesh details add a subtle, sophisticated touch without compromising comfort or absorbency.
Every style has its own purpose in our collection. For example, high-waist designs gently support your core through heavier days or bloating. Hipster and bikini silhouettes rest low on the hips for a minimal, everyday feel. Thongs create a barely-there layer for light spotting or use alongside a cup or disc, while briefs and boyshorts deliver fuller coverage for overnight wear or when you want a little extra reassurance.
How Fit Shapes Everyday Comfort
Finding your fit should feel empowering rather than stressful, so let’s jot down a to-do list. Start by measuring at your widest hip and comparing your number to the sizing chart. A snug fit creates gentle security for active days, while a looser fit can feel relaxed during downtime or overnight use.
As your cycle shifts, so might your preferences. Some people reach for lighter styles during the first or last days of their flow, then move into fuller coverage during sleep or higher-activity periods. Paying attention to these patterns helps you create a rotation that matches your rhythm. Reusable period care invites that kind of personalization, as every fabric, fit, and absorbency level meets a different need. Over time, your favorite styles will become part of your routine, carrying you through your cycle with comfort that feels intentional and effortless.
Wearing Period Underwear with Cups or Discs
Pairing period underwear with a menstrual cup or disc can transform heavy flow days into an easier, more comfortable experience. This combination creates a two-layer system that works with your body rather than against it, offering both internal collection and external protection.
- Dual-layer security for heavy flow days: Menstrual cups and discs collect fluid internally, while using period underwear adds a protective outer layer to absorb spotting or overflow. Together, they minimize bathroom trips and create peace of mind through long workdays, travel, or overnight rest.
- Comfort that adapts to every stage: Many people use this setup when recovering from postpartum changes, hormonal shifts, or surgery. The gentle, breathable fit of our bladder leak underwear adds extra assurance when your body needs more care.
- Freedom for movement and routine: Pairing a cup or disc with workout underwear keeps you dry and supported during exercise or long commutes. The lightweight, flexible gusset manages moisture without bulk, making it an easy choice for active days.
- Reusable care that respects your body and the planet: Both products are washable and designed for long-term use, reducing waste while maintaining comfort. This routine supports your natural rhythm and aligns with our unwavering commitment to body-safe materials.
Make the Switch
Navigating periods shouldn’t feel overwhelming or isolating. That’s why we built our period underwear from the ground up, knowing that comfort, sustainability, and confidence shouldn’t be trade-offs. More than a product decision, choosing reusable is a quiet act of self-respect and environmental stewardship that ripples outward. When you choose reusable period underwear, you’re joining a movement grounded in science, empathy, and the simple belief that everybody who menstruates deserves thoughtful care.
Periods mark life in motion. For some, that means bleeding for the first time. For others, it means healing after hormonal changes, surgery, or postpartum recovery. Wherever you are in that journey, using period underwear creates ease through every stage, from the heaviest flow days to more spotty moments. This menstrual underwear guide exists to help you find options that meet your needs while honoring your body’s natural rhythm.
By making the switch, you’re not only supporting a cleaner planet, but you’re also investing in yourself with body-safe, breathable, and consciously sourced materials. Let’s make every period a little more empowering, together.

Frequently Asked Questions About Using Period Underwear
Can I use period underwear alone on heavy days?
Absolutely. You can use period underwear solo or in combination with other reusable products like menstrual cups or discs on heavier flow days. Our high-absorbency styles are designed to give you the confidence to move through your day without worrying about leaks or discomfort. We encourage you to listen to your body and find the combination that feels right for your unique flow.
Are there different styles of period underwear?
Yes! Our period underwear comes in a variety of styles, absorbencies, and fits to suit your preferences, whether you love the everyday feel of a classic brief, the subtle comfort of a bikini cut, or extra coverage with a high-rise. You can explore styles that match your flow, your wardrobe, and your comfort needs. Because our periods, our bodies, and our style are all beautifully individual.
How do I know when to change my period underwear?
Just like with pads or tampons, your body gives you signals. If you start to notice dampness, or if your underwear feels heavier, it’s probably time to swap to a fresh pair. Because we don’t add fragrance or chemicals, any scent changes are also a sign. Always trust your own comfort first, and remember, changing underwear more often is a preference, not a strict rule.
Can I wear period underwear for light bladder leaks?
Definitely. Our leakproof technology isn’t just for periods. It’s also designed to absorb and lock away light bladder leaks, so you can stay dry and confident, whether you’re managing postpartum changes, riding out hormonal shifts, or just need a little extra support. Body changes are natural, and we’re here for all of them.
Can I wear period underwear overnight?
Yes. Sleep easy, our period underwear offers reliable overnight protection so you can rest (and dream) without having to sleep on towels or worry about morning messes. The absorbent layers work while you do nothing at all, so you can greet the morning feeling comfortable and fresh.
Does period underwear smell?
Our underwear is thoughtfully designed to lock in fluids and minimize odor naturally, without added fragrances or chemicals. Breathable, body-safe fabrics mean moisture stays away from your skin, helping to reduce the conditions that cause odor in the first place. Keeping your period underwear clean also helps maintain freshness.
Is period underwear safe for sensitive skin?
Absolutely. We use carefully sourced, high-quality materials that are free from toxins and harsh chemicals. Our products are crafted with sensitive skin in mind, letting your body breathe and minimizing irritation. We believe comfort should never come at the expense of health.
How do I wash period underwear?
Rinse your underwear with cold water as soon as you can after use to remove excess fluid. Then, toss them in the wash with your regular laundry using mild detergent. Hang dry to preserve the fabric and the environment. Caring for your period underwear this way keeps them performing at their best for cycle after cycle.
