Bamboo underwear and polyester underwear. Both are some of the great titans of our age. And they’re better than cotton underwear in terms of breathability. But we argue that bamboo is far superior than polyester nine times out ten.

Here’s why:

Polyester fabrics aren’t the best fitting, nor best for your skin either. But they are used because polyester fabrics are cheaper and easier for manufacturers to produce.

It's the same reason why manufacturers use corn syrup instead of real honey to save money. In fact, polyester has been labelled the biggest enemy to your skin and health in your own home. 

Here’s why polyester underwear is bad for you:

• It’s a synthetic material and has many toxic chemicals. It’s basically thermoplastic and it out-gases tiny plastic molecules whenever heated.
• When polyester underwear are dried in a clothes dryer, the highly toxic chemicals get released into your home and the environment. 
• The fabrics used to make polyester underwear are often treated with formaldehyde and ammonia to make the fabric soft. 
• According to the National Institute of Health, polyester underwear for men are a 100% effective contraceptive. 
• More studies show it causes sterility and impotence in men. 
• Polyester touching your skin can cause rashes, itching, and redness. It can also cause eczema, dermatitis, and blistering.
• Toxic metals and chemicals like cadmium and chromium are used in textile dyes, which are also used in polyester underwear.

This is all bad news, however, there is some good news.

Here’s why bamboo underwear is good for you:

Less Nasties

After speaking about toxins and heavy metals in polyester, this one is a shocker right? Bamboo underwear doesn't contain formaldehyde, perfluorochemicals, and anything else you can't properly pronounce. I have a rule of thumb, if you can't pronounce it properly, you shouldn't have to live with it 24/7.

Bamboo underwear is more effective at keeping bacteria at bay. And it's also hypoallergenic if you have sensitive skin. Less bacteria in and around your nether region means the distinctive smell you might be accustomed to won't be as strong.

In fact, that smell might not even exist at all after wearing bamboo underwear. It's also just plain healthier if your undies can naturally inhibit bacterial growth.

Breathability

Offers unrivalled breathability, is fast drying, and keeps you feeling fresh and dry all day long. It's made of super fine and soft viscose rayon. This is derived from baboon plants and results in one of the softest fabrics out there.

Bamboo viscose fabric has tiny holes that allow for increased airflow and evaporation -- no matter how sweaty you are. And if I'm being honest here, that's even if you get sweaty. Why did I say that? Because bamboo fabric's increased breathability also means natural thermo-control, as excess heat escapes through those tiny holes I was talking about earlier.

Comfortability 

Bamboo underwear is one of the softest fabrics out there. It's soft, luxurious, and leaves you feeling like an Arabian king with his imported silks, maybe even better. It provides a gentle touch on your skin, and nether regions, which is crucial to prevent itchiness and chafing. Bamboo is naturally anti-chafing, which will leave you feeling fresh and ready to go -- especially after a big night out on the town ;)

Your undies may seem like just a pair of underwear, but they’re the pair of underwear that you’ll wear to your next big job interview, when you watch the grand final or even when you get married. So they’re a little more important than just undies. 

Comfortable underwear can make a world of difference in your life and in your confidence, so you want to get a pair that suits you well.
