Menstrual panties are a type of women's underwear made for period use. Period underwear is crafted from a highly absorbent fabric. The fabric is used for the entire panty with added layers at the crotch portion for maximum period blood absorbency. The result is leak-proof underwear for women that can be re-washed and reused.
Some women prefer using period panties at the beginning of their cycle. The first few days tend to be heavy flow days, and women like to use a pad or tampon while they are wearing menstrual underwear just to be extra safe. Therefore, the panties can absorb any unexpected leakage or overflow from their sanitary products. Menstrual panties for heavy-flow days are usually lined with thicker fabric and have a few more layers at the crotch area. Some women only use menstrual panties towards the end of their period. Since the last few days of a period are lighter, period underwear for women can be worn on its own. It can easily catch and absorb small amounts of period blood for an emergency.
Period underwear for girls in their teens can offer extra security, especially when their periods occur while they are at school. As mentioned, women like to use their period panties as plan B for when they use tampons or pads during a heavy flow. Teen period underwear can lessen the anxiety of young girls when they have heavy periods at school or while they do any of their extra-curricular activities. For some teen girls, using hygiene products like tampons could be scary, but that matters not because they can still use the pad with the underwear. Teenagers do have a crazy amount of hormones, which makes the period crazy. Sometimes, the blessed gift of womanhood could show up unannounced, which might not always be a pleasant surprise. Therefore, they do not have to worry as much about blood leakage through their clothes.
The common one is washable menstrual underwear. It is made from thick and durable fabric that can be reused several times with a bit of soap and water after each use. On the other hand, disposable menstrual panties are made from slightly thinner but still absorbent fabric. They are not meant to be worn or washed as they are not as sturdy as washable panties. Disposable period panties should be thrown out right after use. Many women like to keep spare disposable menstrual underwear in case of early periods at night.
