When To Replace Your Period Underwear?

If you’ve recently started using period underwear, you already know how amazing they are for comfort and convenience. But just like everything else in your wardrobe, period undies have a lifespan. Here's your go-to guide on when to replace them and how to make them last as long as possible. 

How long will period undies last? 

So you might be wondering, “how long will my period undies last?” With proper care, they can last you for about a year.

However, it's important to watch out for signs that indicate it's time to replace them: 

• Absorbency issues: If they’re not absorbing as well as they used to 

• Persistent odours: If they start to smell, even after washing 

• Fabric wear: If the fabric is getting thin, holes are appearing, or the elastic is starting to wear 

• Incorrect fit: If the undies no longer fit you comfortably and snuggly (without being too tight or too loose). 

But remember, if you notice changes in your body shape or size, or if the elasticity starts to break down, it might be time to shop for some new ones to make sure that you always have the comfort and protection you need! 

How long can you wear period underwear? 

For those with a lighter menstrual flow, you can comfortably wear your period underwear throughout the day. Think of them like regular undies - pop on a fresh pair in the morning, and you’re good to go until your evening shower.  

At night, you can definitely sleep in them, but make sure to switch to a fresh pair in the morning. That’s about every 8 to 12 hours, depending on your needs. If your flow is heavier, you might need to change them every 6 hours or so to avoid any leaks.  

How often should you change period underwear? 

This one’s all about your flow. Here’s a quick guide: 

Light flow: Change every 12 hours 

Moderate to heavy flow: Change every 6-8 hours, or whenever you feel some wetness. 

Always check the instructions for your period undies as different brands and products will vary.  

How Much Blood Can Period Underwear Hold? 

Triumph’s Medium Absorbency Period Pants, for example, can hold the equivalent of 3 regular tampons. That’s pretty impressive, right?  

Different brands and styles have different capacities, so always check the specific information on yours. 

How many pairs of period underwear do you need? 

This can vary depending on your menstrual cycle and laundry routine, but having around 5-7 pairs is a safe bet. This way, you can change regularly and always have a clean pair ready to go. 

Proper care to extend the life of your period underwear 

To keep your period undies in top shape and help them to last as long as possible, follow these tips: 

1. Rinse after use: Rinse them in cold water after each wear 
2. Wash gently: Use a mild detergent on a gentle cycle and skip the fabric softeners 
3. Air dry: Let them air dry by laying them flat or hanging them up. Avoid the dryer - it can damage the elastic and the absorbent layers. 

Keeping your period underwear in good condition is all about knowing how to best care for them and when they need to be replaced. With these tips, you’ll get the most out of your Triumph period underwear and enjoy all the comfort and protection they offer.
