Why don’t you have period underwear with a higher capacity?
The AllMatters period underwear can contain up to 10ml of flow – the equivalent of 1-2 regular tampons. It’s estimated that an average cycle lasts for 5 days and you lose an average of 30 to 72ml of blood. The daily average being 14ml per day. This is why we recommend that you have 3-4 pairs of underwear and that you change them every 8-12 hours.
You can, however, wear period underwear for as long as your flow allows – some can wear it for a full day, while others use it as a backup for a cup or tampon (if their flow is heavier).
