still have questions?

We have answers.
Can you wash period underwear with other clothes?

Yep! Washing machines will dilute the contents almost immediately, and your other clothes should not stain if you're washing on cold.
What temperature should I wash them at?

Machine wash the underwear on cold to keep them in tip-top shape. The standard cold wash is 30C.
How long do period underwear take to hang dry?

The drying time of our period-absorbing underwear depends on the style — moderate absorbency styles shouldn’t take longer than 10-12 hours to dry, and super absorbency styles shouldn’t take longer than 19 hours to dry under non-humid conditions.

Drying times may be affected by humidity levels and the airflow of the space you hang them in.
Oops, I put my them in the dryer! What will happen?

Don't panic — a few cycles in the dryer probably won't hurt period-absorbing underwear. However, repeated exposure to the heat from dryers or irons will affect the underwear's elasticity, which helps prevent leaks, so don't make it a habit!

Pro tip: Use a mesh laundry bag to separate them from your other clothes for easy removal from the wash while the rest goes in the dryer.
The underwear have an odor after washing; what can I do?

Our period-absorbing underwear is ultra-absorbent, helps control odor, and wicks moisture to help keep you fresh and dry. Follow our care instructions to keep your undies in tip-top shape.
Will they shrink?

Follow our simple care instructions to maintain your period underwear's performance. Replace them at 30 washes.
