Switch from relying on disposable menstruation products to wearing incredibly comfortable and machine-washable bikini panties that will protect you every day of your cycle. These period panties can also double as postpartum underwear. The underwear gusset is our built-in liner that absorbs up to 8 tampons worth of liquid, and is 23 cm long in this bikin fit. It’s quick-drying, bulk-free, and the top layer next to the skin is made with modal seaweed fabric.
