How does period underwear work?

Period underwear absorbs all sorts of leaks - from period flow and bladder leaks to daily discharge and sweat.

Not all period underwear is the same. Saalt leakproof underwear uses proprietary, patent-pending technology to wick moisture way from your body to keep you feeling dry. You can learn more about how it works and what makes Saalt unique here: The Magic Behind Saalt's Leakproof Underwear.

Will period underwear smell?

No, when cared for properly, your Saalt Wear should not smell! Saalt Wear is treated with a bio-based solution for odor control that removes sweat odor and eliminates bacteria to keep you fresh and odor-free.

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 Saalt Wear leakproof underwear in cold water to help avoid staining. Then, hand wash or machine wash on cold, preferably in a Saalt Mesh Laundry Bag intended for delicates. You can use detergent (Saalt Period Underwear Detergent is ideal) but pass on the fabric softener, bleach, and iron to protect the tech. Proudly hang dry—energy efficient and free. We recommend avoiding putting Saalt Wear in the dryer, as high temperatures can degrade the elastics and fabric over time.

Can I wear them all day?

Go with your flow! How long you can wear your Saalt Wear leakproof underwear before needing to change will depend on your flow and the absorbency level of the style you choose. If you are free bleeding on your heavy day, you may need to change into a fresh pair after a few hours of wear. If you’re wearing your Saalt Wear as a backup to a cup or on a light day, you may be able to wear it all day. We recommend trying Saalt Wear for the first time at home so you can see how your pair works best for your body and ~flow~.
