Period-proof panty guide

Is the period panty leak-proof even if you bleed heavily?

_{Female Engineering® make period-proof underwear for all flow levels, from light to heavy bleeders. For those worried about bleeding more, we recommend starting out by wearing the period panty at home during a heavy bleeding day. That will put it to the test and make it easier to figure out how it works.​}

How many times can they be used and washed? How long will they last?​

_{Our period panties are made to last at least 50 washes, which is far above industry standards. The number of washes is determined by the gusset absorption layer in our Engineered Leak Tech™, which has an antibacterial and anti-odour treatment that tends to lose a little bit of effectiveness after 50 washes. It is likely that the function of the panty will last longer though, but 50 washes is what we can guarantee. However, the fabric, form and fit of the panty will last a lot longer. If a panty is worn and washed once per menstruation cycle, it will last around 4 years.​}

How much blood can the period underwear hold?

_{Our period-proof underwear come in different absorbency levels, much like disposable menstrual products:} 

_{5 ml Mini ≈ ½ tampon/panty liner}

_{10 ml Light ≈ 1 tampon/pad} 

_{20 ml Medium ≈ 2 tampons/pads} 

_{30 ml Mid-high ≈ 3 tampons/pads} 

_{40 ml High ≈ 4 tampons/ pads} 

_{50 ml Super ≈ 5 tampons/ pads}
