How Often Should You Buy New Underwear?


How often should you buy new underwear? That is the question and the answer is less straightforward than it might first appear. After all, a number of men probably think that their underwear should literally wear out its welcome, staying in the rotation until it features gaping holes and dangling threads. However, those same men are potentially ignoring things like harmful bacteria, which accumulate over time and can lead to urinary tract infections, amongst other things.


If you don’t feel like reading 1000+ words on your undies, allow us to spare you some of the suspense. According to most experts, you should replace your old underwear with new underwear once every 6-12 months. While that might seem like a somewhat broad window of time, we know dudes who’ve worn the same undies and briefs for over a decade so it’s actually pretty specific.



When you do replace your underwear, stick with a quality brand like Tani USA. Their SilkCut Collection is made from Micro Modal Air which is literally stronger and finer than silk.  The SwissTouch Swiss Cotton Boxer Brief and Boxers are quite simply top of the line, offering all-day comfort, mobility, and breathability. The AirFit collection is similarly superior and more economic by comparison, with a lower price point and an extra pair in every multipack.


Meanwhile, some of you might be asking yourself: did they say something about harmful bacteria living in my underwear? We did indeed. Here’s everything you need to know about your undies.


Underwear & Bacteria: The Ugly Truth

Here’s the ugly truth. Your underwear gets up close and personal with your skin and private areas and takes in a lot of living bacteria as a result. Furthermore, your laundry water isn’t nearly as clean as you think it is. Even after you do a wash, your underwear can reportedly contain up to 10,000 living bacteria, including E.coli.


While most living bacteria aren’t innately harmful to your personal health, some of them can become so over time. By holding on to those undies for over a year, you’re allowing everything from E.coli to dust mites to accumulate. Eventually, this could lead to dilemmas such as urinary tract infections, rashes, or allergies.



How Often Should You Buy New Underwear?

Nearly all outlets and experts agree that you should replace your old boxer briefs, briefs or boxers with new underwear once every 6-12 months. If you’re the kind of guy who has an entire drawer full of boxers and briefs and therefore maintains a fairly broad rotation, you can probably hold on to each pair for a full year.


On the other hand, if you’re the kind of guy who’s been rotating between the same four pairs of undies for the last six months, it’s time to swap them out. And remember: this goes for everyone, including men who wash their underwear on a regular basis.


There are also other factors to consider, many of which will vary from person to person. For example, maybe you have specific underwear that you rock to the gym or on hikes and jogs. Naturally, those underwear are going to break down faster and gather more bacteria. For obvious reasons, they should be replaced sooner than your other pairs.


How Often Should You Wash Your Underwear?

It doesn’t matter if you wear men’s boxers, briefs, or boxer briefs - Generally speaking, you should wear your undies for no longer than a full day and launder them before wearing them again. If you wear the same pair for two days in a row, will it kill you? No, it will not. You might start to itch a little, though.





How Do You Know When it’s Time to Replace Your Underwear?

A number of men don’t remember when they bought their underwear, which can make proper replacement something of a chore. In this scenario, you can rely on physical cues to determine when your underwear has run its course. For instance, when the material starts to sag or the color begins to fade or the elastic waistband gives out, it’s time for those undies to go.


Underwear replacement is more about comfort and performance than it is about personal health, even if you are at risk for certain types of infections or rashes over time. At the end of the day, you don’t want to feel itchy or irritated in your most sensitive area and this alone is enough reason to practice a proper wash and replacement regimen.


How Many Pairs of Underwear should a Man Have?

No two men are exactly the same and nor are their lifestyle habits. Some men go to the gym on a regular basis while others don’t. Some men travel for work while others never get out of their robe. Nevertheless, most experts agree that every grown male should have at least 20 pairs of underwear in his wardrobe. Any combination of mens boxer briefs, boxers or briefs works.


What is the Best Fabric for Underwear?

Ultimately, you want a material that’s long-lasting, breathable, and tight-fitting. If only maximum comfort and performance will suffice, look no further than Micro Modal Air. Tani USA is the only underwear brand to offer this new and innovative underwear fabric. 


As a base material in underwear, boxer briefs, t-shirts, and other apparel, Micro modal air delivers smooth texture and premium support, all while feeling somewhat cool against the skin. Put simply, this is the perfect material for all-day wearability.
