Work out without worrying about leaks

The best workout underwear women can count on is the kind that handles both sweat and flow. That's Saalt.

Our gym underwear supports your movement while keeping leaks in check.

Each pair provides secure, stay-put protection that won't ride up, roll down, or announce itself under your gym shorts.

Customize your coverage and absorbency to match your intensity.

Choose Your Absorbency Level

Every day of your cycle is different, so your workout underwear should be too.

  • Light holds up to 2+ light tampons or 1+ liner. Best for spotting, sweat, discharge, or backup to a cup, disc, or tampon during your workout.
  • Regular holds up to 3 tampons or 2 pads. Great for regular period flow, light bladder leaks, and active days when you need reliable protection without bulk.
  • Heavy holds up to 4 tampons or 3 pads. Ideal for heavy flow days, postpartum wear, and bladder leaks when you need more coverage.
  • Super holds up to 8+ tampons or 6+ pads. Maximum protection for your heaviest days, overnight wear, and postpartum recovery.

Match your protection to your activity and your cycle day.

    I am in love with these undies! I wore them on my heavier days for half a day, and they did a great job. No leaks, no stains! The fit was perfect; great for when you are wearing low rise pants.

  • Natalie E.

    Is it weird that I was actually looking forward to my period to be able to rock these cute undies? Like lots of people said, these are cuter than a lot of my regular underwear and it's so nice to finally ditch the backup pad. Can't wait to get more in different colors to get me through period week!

  • Michelle C.

    These are great! The period panties I've ordered from other brands feel like thin diapers mixed with granny panties. These are cute, they work, and I'm definitely going to buy more!

  • Lani D.

    Love it!!! It's so soft and you wouldn't even know that it was a period panty. Will definitely purchase more & recommend to all my friends & family! I've already bought some for my teenager daughter.

FAQs on Saalt Workout Underwear

Is Workout Underwear Different From Regular Period Underwear?

Workout underwear needs to do more. It has to stay secure during movement, remain invisible under tight clothes, wick sweat, and handle leak protection. Regular period underwear might prioritize comfort and absorbency over athleticism. Saalt gym underwear delivers the whole package: workout performance plus period protection.

Where Can You Buy High-Performance Workout Underwear That Does Not Ride Up During Runs?

Right here. Saalt workout underwear is engineered to stay exactly where you put it, whether you're running sprints, crushing a 10K, or just trying to survive leg day. Our Seamless collection features bonded edges and four-way stretch that hug your body without creeping, bunching, or requiring mid-run adjustments. This is gym underwear that actually behaves.

What Should You Look for When Choosing the Best Underwear for High-Intensity Workouts?

Start with fit: does it stay put without digging or rolling? Then check for breathability and moisture-wicking fabric. Finally, look for invisible seams if you wear tight activewear. Saalt gym underwear nails all three, and adds leakproof absorbency for periods, sweat, and bladder leaks.

What Makes Saalt’s Workout Underwear Different From Regular Underwear?

Saalt workout underwear goes deeper than standard gym underwear. Our patented gusset absorbs sweat, discharge, light bladder leaks, and period flow while remaining thin, dry, and safe. Designed to stay in place through every rep with no riding up or rolling down, it's workout underwear women can actually count on. The Seamless collection offers invisible lines and real protection.

Why Is Workout Underwear Especially Important For People Who Menstruate?

Working out on your period shouldn't require extra layers, backup pads, or constant worry. Saalt's workout underwear absorbs flow while staying dry, eliminating the need for disposables during exercise. Our Seamless collection disappears under leggings without bunching.

Can the Wrong Workout Underwear Cause Skin Irritation or Infections Over Time?

Absolutely. Underwear that traps heat and moisture against your skin creates a breeding ground for irritation and infection. Saalt gym underwear is built differently, with moisture-wicking fabric that stays dry through even your sweatiest workouts. Made without PFAS, no harmful finishes, just thoughtful design that respects your body.

How Does Saalt’s Workout Underwear Perform During Intense Activity?

What Absorbency Options Are Available For Saalt Workout Underwear?

Every flow is different, so our workout underwear love comes in Light, Regular, Heavy, and Super absorbencies. Light works for spotting and backup; Regular handles moderate flow during training; Super offers maximum protection for heavy days.
