Period panties for teens offer a new way to experience your period for the first time. For many teens and tweens, traditional products like tampons can feel intimidating, especially when you're still adapting to your body’s changes. Internal products aren’t always the right fit at this stage, and that’s completely okay! Pads are often the go-to alternative, but let’s be honest: They can feel bulky, shift around during the day, and aren’t always comfortable during sports or sleep.
Period underwear offers a more familiar way to manage your period, with no strings, wings, or adhesives attached. Just pull them on like normal undies and you’re good to go. At their core, they look and feel just like your favorite pair of underwear: soft, stretchy, and form-fitting. But beneath the surface, that’s where the magic happens. These innovative undies use carefully engineered, multi-layered fabric technology to absorb menstrual flow, lock in moisture, and keep leaks at bay.
How Period Underwear Keeps Leaks In Check
Have you been wondering, “Where can I find affordable and reliable period underwear for girls?” Look no further than Saalt! Our teen period underwear is made with a patented gusset that’s thin, flexible, and anything but bulky, because period care shouldn’t weigh you down. Our gusset features four layers that work together to deliver powerful leak protection with a barely-there feel:
- Moisture-Wicking Top Layer: The top layer pulls fluid away from the skin to keep you dry, cool, and comfortable, even during after-school activities or long days in class.
- Super Absorbent Core: This second layer can hold up to 3x its weight in liquid, locking moisture in without a soggy or heavy feeling.
- Leak-Resistant Barrier: A breathable third layer helps stop leaks before they become stains, no matter how active your day gets.
- Dreamy Soft, Stretchy Outer Fabric: The last layer moves with your body and stays put for all-day comfort. You won’t find any awkward shifting or bunching here!
Never Treated With PFAS
We do not use per- and polyfluoroalkyl substances (PFAS) in the fabrics or finishes of our girls’ period underwear. The U.S. Environmental Protection Agency notes that PFAS exposure may disrupt natural hormones, which is something that growing bodies shouldn’t have to worry about. That’s why we thoughtfully craft our period underwear for teens with durable, sustainable materials that feel good on the skin without scratchy seams or bulky layers. After all, your most delicate areas deserve nothing less than the best.
Why Parents & Kids Love Reusable Over Disposable Period Care
The average person who menstruates will have around 450 periods in their entire lifetime. When you think about how many single-use period products that equals, it adds up fast. The average person uses more than 10,000 pads or tampons total, and in the U.S. alone, about 20 billion menstrual products are thrown away each year. According to the World Health Organization, most of these products are made with over 90% plastic. Since many of them take hundreds of years to break down, the products you used during your first period could still be sitting in a landfill when you’re a great-grandparent!
Eco Impact: How One Pair Saves Hundreds Of Disposables
Switching to reusable period underwear for girls is a small yet impactful way to take control of your cycle and reduce your environmental footprint. Just one pair of Saalt’s leakproof underwear can replace hundreds of single-use products over time, cutting down on the plastic waste that adds up month after month. Rather than tossing single-use products in the trash during every cycle, you can simply wash and rewear. It’s an easy habit that feels good and does good.
For growing girls especially, this kind of sustainable swap helps build a positive relationship with period care from the start: One that’s thoughtful, low-maintenance, and better for the Earth. Small changes add up, and this one has a big ripple effect.
From Class To Sleepovers: Period Protection That Keeps Up
Periods shouldn’t interrupt life’s most meaningful moments, whether you’re scoring a winning goal at soccer practice or staying up late at a birthday sleepover. While being concerned about leaks is normal, the right support can zap those worries away. With built-in absorbent layers and ultra-soft materials, the best teen period underwear is designed for round-the-clock comfort and dryness.
School Days, Simplified
From first bell to last period, Saalt’s Leakproof Teen Brief style is breathable, flexible, and never treated with PFAS. Its thin, moisture-wicking gusset helps lock in leaks without the bulk of traditional pads. Made from lightweight, soft-stretch nylon and spandex, the full-coverage fit feels secure and soft against your skin. So, you can focus on the things that matter, like passing a note to your crush or wondering what’s for lunch.
Whether you’re at school, practice, or hanging out with friends, you’ll have reliable protection that feels just like your favorite pair of underwear (only better). Keep an extra pair in your backpack or locker, and you’ll always be ready whenever your period shows up.
Sleepovers Without The Stress
Late-night movies, borrowed sheets, and early morning pancakes shouldn’t come with the worry of stains or leaks. Our designs are machine washable and reusable, so you can rest easy (even on heavy flow nights). For instance, our Leakproof Teen Sport Short offers Super absorbency (equal to 6+ pads or 8+ tampons’ worth of flow), with a 3" inseam and full gusset for reliable, front-to-back protection. A hidden silicone print inside the leg keeps these period shorts anchored, and a moisture-wicking finish pulls sweat away. Wear it under uniforms, dresses, or on its own for next-level leakproof protection for teens. Game day, practice, or just lounging at home? You’re covered.
Finding The Right Size For Growing Bodies
Puberty brings change, and period care should support that. Finding the right fit for period underwear starts with understanding how growing bodies move and shift. That’s why Saalt’s Teen Collection is made with a lightweight, stretch-friendly nylon and spandex blend that adapts as you grow. Whether it’s for school days, practice, or downtime, our styles are built to move with you, so you can feel comfortable and protected through it all.
Youth Sizes, Real Fit
Sizing for tweens and teens can be tricky. Growth spurts and changing shapes mean what fits one month might need a little extra room the next. That’s why the best period underwear for teens uses stretch-friendly fabrics and adaptive cuts that move naturally, providing full coverage and softness where it matters most.
Saalt Teen Wear comes in sizes Youth Small through Youth XL, designed to fit waist and hip measurements from 23" to 29" and 29" to 38", respectively. For the most accurate sizing, we recommend using a flexible measuring tape to measure your natural waist (at your belly button) and your hips at their widest point.
Support That Feels Just Right
Both our Teen Brief and Sport Short styles run true to youth sizing and feature soft, flexible fabric that offers full coverage without digging in or shifting out of place. The Teen Brief features a classic mid-rise fit, while the Sport Short provides high-rise support with extra coverage.
Just as important as the fit is the ease of getting them on and off, especially after sweating it out at soccer practice or rushing out the door to make it to class on time. That’s why accessible sizing charts and clear product details matter. They help take the guesswork out for both teens and parents, making it easier to find that just-right pair. A proper fit lets you feel empowered, capable, and ready for anything your day brings.
Care That Helps It Last
With the right care, your Saalt Wear can go the distance. After each use, rinse your period underwear in cold water to help prevent stains from setting. From there, you can either hand-wash or toss them in the washing machine on a cold cycle. For best results, use a gentle detergent and place them in a Saalt Mesh Laundry Bag to protect the fabric and leakproof layers. While tossing them in the dryer might be tempting, air drying is the way to go. It’s easier on the environment and helps preserve the stretch and softness of your Saalt Wear for the long haul.
By following these simple steps, you can keep your Saalt Wear feeling fresh and performing at its best. It’s an easy routine that helps you get the most out of every pair, month after month.
