Are period pants hygienic?

If you're thinking of switching to period pants, you may have some questions about hygiene and how hygienic period pants actually are, especially if you've never worn them before. So in this post, we'll explore why period pants are hygienic and how to keep them smelling fresh after each use.

First of all, let's clear one thing up. Period blood is hygienic, which means so are your period pants. Menstrual fluid is a part of life and nature, and so, no, your period blood is not dirty or gross. That is simply a misconception, and people need to understand that period blood is just the same as any other blood that comes out from our bodies. 

Keeping your period pants squeaky clean

As with any garment, how often you wash your period pants will affect how clean they are. If you wear them for multiple days in a row without washing them, they're going to start to smell. The same is true of regular underwear. The key to keeping your period pants clean is to wash them often.

There are a few different types of period pants on the market, and each has its own washing instructions. For example, some period pants can be thrown in the washing machine, while others need to be hand-washed. Be sure to read the care instructions before washing your pants.

In general, period pants are no more or less hygienic than regular underwear. The key is to wash them frequently and according to the care instructions. Here’s our guide on how to wash and dry your period pants the right way.

Key benefits of wearing period pants

  • They work exactly like normal pants, but they have three layers of absorbent material. Which means they are perfect for periods and urine leaks. 
  • They can absorb up to 4x tampons worth of menstrual fluid, which is bloody amazing! 
  • Over the course of their 100-wash lifetime, these reusable game changers prevent 400 plastic disposables from ending up in landfills.
  • Since they are worn externally, unlike tampons and menstrual cups, toxic shock syndrome is not a concern.

Do period pants smell?

Period pants are designed to collect menstrual fluid and keep your pelvic area dry and odour free. They are made from super moisture-hungry organic cotton that helps to keep you dry and never smelly. 

Of course, if you wear your period pants for too long, they might feel a bit sticky. This is why it is important to wash your period pants after every use to prevent the fabric fibres from over-absorbing any odours or moisture. So if you don't wash your vagina or your period pants frequently, they may smell or feel sticky but once washed, they will smell just like new.

How long can you wear period pants?

As mentioned above, our period pants are designed to contain enough absorbency to hold four tampons at a time and for use for up to 10 hours. And with the ability to absorb and prevent leaks, the built-in organic tech keeps things fresh and hygienic. However, if your flow is heavy, you may have to change them a bit more often.
