Do period panties feel wet?

How do I wash period panties?

Is it safe for me to sleep in period panties?
Yes, you can sleep in our period panties. Our period-proof panties are designed to perfectly hug your curves and give you optimal protection, also during the night. If you are unsure about your flow during the night, we recommend you opt for a higher absorbency, as the absorption gusset on our high-waisted styles reaches higher up your back and thereby reliably captures menstrual liquid while you sleep.

Our period panties should not smell if they are properly washed. Please see our wear & care instructions to know how to wash and care for your period panties.
Are period panties breathable? Can they give me an infection?

Are period panties better(safer) than using tampons or pads?
Period panties, tampons, or pads are all equally effective to use during your menstruation. Your monthly cycle can leave you feeling vulnerable, in pain, or insecure - so we believe it’s important to use what personally provides you with the most comfort and confidence. However, period panties are a great eco-friendly choice compared to one-time-use products, such as tampons or pads. They last you just as long as any regular panties would which gives them an important environmental advantage. While tampons in rare cases can be associated with Toxic Shock Syndrome (TSS), there have not been any reported cases of TSS in association with the use of period panties.
Is it safe to use period panties for training?
Yes, you can use our period panties for any type of workout, excluding swimming. The panties are designed to keep you comfortable and dry during any physical activity.
