    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.

Saalt Wear FAQs

Will workout underwear smell?

When cared for properly, your Saalt Wear should stay fresh no matter what the day brings. Each pair is treated with a bio-based finish that helps prevent odor buildup by neutralizing bacteria and moisture during activity. From long training sessions to daily wear, our athletic underwear keeps you comfortable and confident through every move.

Can I put it in the dryer?

Take good care of Saalt Wear, and it will take great care of you. After use, rinse your workout underwear in cold water to release stains. Next, hand wash or machine wash on cold, preferably inside a Saalt Mesh Laundry Bag for seamless or lace delicates. We recommend skipping the bleach, softener, and iron to preserve your gym underwear. Once washed, hang dry to protect the fibers and stay energy-efficient. Avoiding the dryer helps maintain the strength of the gusset and elasticity.

Can I wear them all day?

Go with your flow! Flow levels vary, so comfort and absorbency depend on your body and chosen style. For example, many use Saalt Wear as a backup during high-flow workouts or as gym underwear on lighter days. Our leakproof layers hold up to 3x their weight in liquid, making them perfect for long days, training sessions, or post-exercise rest. We recommend trying your pair at home first to learn how each style performs for your workout routine. As always, if you’re wearing Saalt Wear, you can easily pair it with a cup or disc for all-day wear. 

Does Saalt Wear have PFAs (polyfluoroalkyl substances)

You can rest easy knowing we do not use any PFAS in our fabrics or finishes. Every material is tested for known hazardous substances, including PFAS and other harmful chemicals. As a Certified B Corporation, we’re committed to designing sports underwear for women that’s safe, sustainable, and high-performing. Learn more on our PFAS education blog.
