At fluxies, we're passionate about making your period as stress-free as possible with our innovative period pants. Whether you're hearing about period underwear for the first time or just curious about how they work, this guide is perfect for you.

What Are Period Pants?

Period pants are cleverly designed underwear that absorb menstrual blood. They look just like your normal underwear but are made to help you stay dry and comfortable during your period. They can completely replace traditional period products, like disposable pads and tampons. 

How Do Period Pants Look and Feel?

Period pants look just like the underwear you wear every day. You can choose from many styles and colours, just like normal underwear. From lace-trimmed to seamless, each pair is made to make you feel great. They’re soft and comfy, so you can wear them all day. 

The Technology Behind Period Pants

Our period pants are made from high-quality, skin-friendly fabrics. The outer layers are often made from materials like organic cotton or modal, which feel soft against your skin. The magic behind how it works happens in the hidden layers:

  • Wicking Layer: This is the layer that sits next to your skin. It moves moisture away from your body to keep you dry.

  • Absorbent Layer: This layer sits just below the wicking layer. It's super absorbent and can soak up to the equivalent of four tampons' worth of blood, keeping you secure for hours.

  • Waterproof Layer: This is a leak-proof layer that stops any blood from getting through to your clothes. It stops leaks so you can feel confident all day.

How Long Can You Wear Period Pants?

You can wear our period pants for up to 12 hours, depending on how heavy your flow is. They’re perfect for both lighter days and overnight use.

  • Super Light to Light Flows: These are great for days when your period is very light. They're comfy and you hardly notice them.
  • Medium Flows: Our medium flow underwear is good for regular days. They keep you dry and comfortable all day.
  • Heavy to Super Heavy Flows: On days when your period is heavy, these pants are prefect. You can wear them during the day or all night long without worrying about leaks.

You can choose the best period pants for how heavy your period is on any day. This way, you'll always feel comfortable and confident!

The Benefits of Switching to Period Pants

Good For The Environment

Using period pants helps reduce waste. Unlike disposable pads and tampons, our pants are designed to last. They can be washed and reused, which is much better for our planet.

Saves You Money

While the upfront cost of period pants may be higher than a pack of disposables, they are more economical over time. Imagine not having to buy pads or tampons every month—your fluxies will pay for themselves in just a few cycles.

Let's look at how much you might spend on period products. The average woman uses approximately 20 disposable pads or tampons every cycle. Over three years, this adds up. Here’s a simple breakdown of how the costs compare:

  • Disposable Pads or Tampons: If each month’s pads or tampons cost £5, that’s £60 every year. Over three years, that's £180.
  • Period pants: If you buy 5 pairs of period pants for an average of £20 each, that's £100 in total. And they can last for three years if you take care of them. That’s much cheaper in the long run.

Comfort and Convenience

Say goodbye to the discomfort of pads or the hassle of tampons. Period pants fit just like your favourite underwear and come without any worries about leaks, shifting, or chafing. They're perfect for overnight use, travel, or any time you prefer not to think about your period.

Choosing the Right Period Pants for You

Different Flows Need Different Styles

We offer a range of period pants designed for different flow levels—from light to super heavy. Choosing the right pair depends on how much you usually bleed in a day. If you're not sure which to choose, start with a style designed for a medium flow and go from there.

Find Your Style and Fit

Period pants come in different styles, from thongs to boyshorts. It's important theey fit well to prevent leaks. They should feel snug but comfortable. Check our sizing guide on each product page to find your perfect match.

Looking After Period Pants

It’s easy to keep your period pants ready for the next wear:
  1. Rinse Them: After wearing them, give your undies a quick rinse in cold water. This helps wash away most of the blood before it sets in. Just hold them under the tap and gently squeeze until the water runs clear.

  2. Wash Them Gently: Once they’re rinsed, it’s time to wash them properly. Pop your underwear into the washing machine. Set it to a cold wash on a gentle cycle. This helps protect the special layers that make your period pants work. Remember, don’t put in any fabric softener, because it can stop them from absorbing well next time.

  3. Air Dry: After washing, hang your period pants up to dry. A good spot is somewhere airy but out of direct sunlight. Avoid using the tumble dryer because the heat can mess up the absorbent and waterproof layers. Hanging them to dry keeps them in great condition and means you can use them again and again.
