Can I wear these without any additional protection?

How do I care for my leakproof underwear? 
Pelvi underwear is machine washable. Wash on a gentle cold cycle, and hang to dry. You can also use a laundry bag to protect your underwear from damage.  
What does it feel like wearing them?
They feel just like your regular underwear, and slimmer than bulky disposable pads. Using reusable leakproof underwear is healthier for your body.
Can I use them for light bladder leaks?
They are perfect for light bladder leaks. Designed to be super absorbent and breathable. The moisture-wicking layer also draws moisture away and fights bacteria to keep you fresh.
