Workout Underwear

Saalt’s workout underwear was designed to be more than just a base layer, it’s protection that moves with you. Unlike typical gym underwear that focuses on fit alone, or athletic underwear made only for breathability, Saalt Wear goes deeper. Every pair includes our patented leakproof gusset, capable of absorbing sweat, discharge, light bladder leaks, and period flow. It’s thin, dry to the touch, and never treated with PFAS, a difference you’ll feel from your first workout. Our performance workout panties were created to disappear under activewear and to stay in place no matter how hard you train.

We tested and re-tested until we landed on the perfect formula: sports underwear for women that feels like regular underwear but performs like a pro. The result is high-performance design paired with intentional comfort, offering support for people who move and bleed. Our Seamless collection is made for workouts, offering invisible lines and reliable absorbency. And if you're looking for the ideal active fit, our seamless period underwear gives you all the protection without the padding or bulk. When movement matters, so does what you wear underneath, and Saalt Wear was built to keep up.

Working out on your period shouldn’t require extra layers, backup pads, or constant worry. That’s why workout underwear is more than a convenience, it’s liberation. Saalt’s performance workout panties offer the support menstruators need to feel secure in movement, without sacrificing comfort or style.

Our patented leakproof gusset absorbs flow while staying dry to the touch, eliminating the need for traditional disposables during moderate activity. Unlike standard gym underwear, which doesn’t account for leaks, Saalt Wear is designed to keep moisture away from your body while maintaining a flattering, stay-put fit.

The Seamless collection is particularly suited for movement, disappearing under even the tightest leggings without bunching or rubbing. For people who want their sports underwear for women to support them through squats, stretches, and sprints, not hold them back, this is a revolutionary shift.

With underwear that works as hard as you do, you're empowered to show up, period or not. And when your cycle calls for softness and recovery, our comfortable period underwear is designed to support you on lighter days or rest days with ease. Wherever you are in your movement, Saalt Wear is there, made to flex, absorb, and empower.

During high-intensity workouts, your underwear should never be a distraction. Saalt’s workout underwear was created to meet the demands of real bodies in motion, bodies that sweat, stretch, and bleed.

Whether you're running long distances, powering through weight training, or moving through an intense vinyasa flow, our Seamless collection delivers next-level support. Unlike basic athletic underwear, which may help with sweat but falls short on leak protection, Saalt Wear integrates a patented gusset that absorbs fluid while staying dry to the touch. This innovation makes our underwear a reliable solution for people who need moisture control and protection that can stand up to hours of high-output activity.

What makes our performance workout panties unique is how effectively they balance absorbency with wearability. Many Saalt styles absorb up to 8+ tampons or 6+ pads’ worth of flow, giving you peace of mind without backup products or changes mid-workout. Our materials are never treated with PFAS, so you can train with full trust in what touches your skin, even when your body is working its hardest. From the first rep to the last cooldown, our sports underwear for women offers invisible protection, all-day comfort, and thoughtful design.

Your gear should work as hard as you do. Saalt makes sure it does.

We know every flow is different, and so is every workout. That’s why our workout underwear is available in multiple absorbency levels, from Light to Super, giving you the power to choose what works best for your body and activity level. The Seamless collection is our top pick for active movement, available in Regular absorbency that holds up during moderate flow and exercise. While gym underwear typically doesn’t absorb anything beyond sweat, Saalt Wear delivers true protection, keeping you dry without padding or extra bulk.

If your day calls for heavier coverage or more comfort, think long commutes, travel, or low-impact rest, we offer styles like the Comfort Brief Super and Cotton Sleep Short. These aren't just soft, they're high-performing, absorbing up to 10 tampons or 7 pads’ worth of flow in select styles.

While those options aren’t ideal for sweaty workouts, they’re perfect for recovery days or overnight wear. When it comes to choosing reliable sports underwear for women, athletic underwear, or your go-to performance workout panties, Saalt Wear offers flexibility, absorbency, and confidence, every day of your cycle.

Everyone moves differently, which is why Saalt offers multiple workout underwear styles tailored to your body and your lifestyle. From high-intensity routines to lighter-flow days or gentle movement, each design serves a specific purpose while staying true to our mission of comfort and sustainability. If you’re looking for performance workout panties, we’ve got a style that fits your pace and your preferences:

Seamless Bikini

The Seamless Bikini is our go-to style for movement-heavy days when you need comfort, flexibility, and invisible lines. It hugs the body without shifting, making it ideal for training sessions, yoga, or any type of cardio. As sports underwear for women, this style offers Regular absorbency with the thinnest leakproof gusset, giving you freedom to flow through your workout without feeling like you’re wearing period protection.

Seamless Brief

For those who want more coverage without sacrificing performance, the Seamless Brief provides a full-coverage fit that moves as you do. This design is perfect for workouts that demand deeper squats, intense movement, or more support through the midsection. It functions as both gym underwear and performance workout panties, staying secure through every rep while keeping you dry and comfortable.

Lace Hipster

The Lace Hipster brings softness and style into the mix, designed for light movement or rest days when you still want leakproof protection. While it’s not intended for high-intensity workouts, it’s a beautifully functional option for lower-flow days, adding confidence with a touch of elegance. If you’re looking for lace period underwear that also works as athletic underwear during gentle activities like stretching or walking, this is your match.

Creating truly effective workout underwear means focusing on both how it performs and how it feels. At Saalt, we take every stitch, seam, and gusset seriously to ensure you stay dry, supported, and unrestricted during movement. Whether you wear our athletic underwear to the gym or for everyday activities, comfort is built into every layer:

Ultra-Thin Gusset

The patented gusset in our performance workout panties is designed to be thin, dry, and highly absorbent. It captures fluid without holding moisture against the skin, helping to prevent that wet, bulky feeling often found in other period care products. Despite its power, the gusset remains subtle and comfortable enough for even the most active workouts.

Stretch-Friendly Fit

Our fabric has four-way stretch built into its design, so it adapts seamlessly to every squat, lunge, and twist. This ensures that your gym underwear stays in place and never digs or rolls, even during high-impact movement. The fit is supportive yet flexible, providing a balance that feels like second skin while still offering total freedom.

Clean, Toxin-Conscious Materials

We use fabrics that are never treated with PFAS and avoid any harmful finishes in the production of our athletic underwear. These choices protect not only your skin, but the planet too, aligning with our sustainable values as a certified B Corp. It’s comfort you can count on, backed by materials you can trust.
