Our materials
Female Engineering’s period panties are made to be used again and again. This is why we design them with great attention to details. Like the material blends, all developed for a soft and barely-there feel. Here are some of the materials we use.
All the cotton we use at Female Engineering is organic, which means it is grown without genetically modified seeds, pesticides, or synthetic fertilisers. But that’s not all – most of our cotton is organic PIMA cotton. PIMA a premium cotton with longer and silkier fibres, making it incredibly smooth against the skin and stronger than conventional cotton.
Polyamide is known for its stretchy and durable features. We mostly use recycled polyamide, which is usually made from pre-consumer fabric waste, but can also come from post-consumer materials like industrial fishing nets.
We use recycled polyester for its stain-resistant and quick-drying features. Recycled polyester is usually made from plastic bottles, packaging, or textile waste.
Your most common questions
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.
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.
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
From heavy period to lighter days:
Based on light panty liner, normal size tampon and normal sized pad. This means that the Mid-high period panty for example has the capacity to hold up to 30 ml of blood, which is almost equal to the total amount of the average menstrual fluid loss per one whole period - which is 35 ml (but varying between 20 and 80 ml).
