Underwear is a staple in every man's wardrobe, but have you ever stopped to consider why we wear it at all? From providing support to keeping clothes cleaner for longer, underwear plays an important role in our daily lives.
Historically, the earliest versions of underwear date back thousands of years, with loincloths and simple undergarments used for modesty and protection. As time progressed, underwear evolved to offer more structure and comfort. Today, modern innovations like pouch underwear and modal underwear are designed with your health, hygiene, and comfort in mind.
The Practical Reasons We Wear Underwear
One of the main reasons we wear underwear is for hygiene. A well-fitted pair acts as a barrier, keeping outer clothing cleaner and reducing skin irritation. It can help prevent chafing, absorb sweat, and protect sensitive areas from friction throughout the day.
But underwear isn’t just about function. It's also about comfort and support. Good underwear should fit well, move with you, and offer the right level of support—especially when you're active.
At Crossfly, we design underwear for men that ticks all the boxes. Whether you're heading to work, out for a run, or relaxing at home, our styles are crafted to keep you comfortable all day.
Support Where You Need It
One of the lesser-discussed but vital benefits of wearing underwear is testicular support. Proper support can reduce discomfort and prevent strain, especially during exercise or long periods of movement.
Crossfly underwear includes an internal Cocoon pouch, designed to provide gentle scrotal support and help keep everything in place. This separation also helps reduce skin-on-skin contact, minimising chafing and maintaining a fresher feel.
Whether you call it ball support, testicle support, or simply a better fit, our patented designs provide what your body needs—without compromising on style or breathability.
Why Breathable Fabrics Matter
If you’ve ever worn underwear made from heavy, synthetic fabrics, you’ll know how uncomfortable it can get—especially in warm weather. That’s why breathable materials are so important.
Crossfly offers modal underwear and cotton underwear, both chosen for their softness and moisture-wicking properties. Modal, in particular, is naturally breathable and feels cool against the skin, making it perfect for everyday use and intense activity.
We’ve engineered our underwear to move with your body, wick away moisture, and stay fresh from morning to night.
A Fit That Makes a Difference
Fit is everything when it comes to comfort. Underwear that’s too tight can cause discomfort, while loose styles may not offer the right support. That’s why Crossfly underwear is available in a range of fits and sizes, including boxers for men and supportive briefs.
Our X-Fly technology also adds convenience, giving you quick and discreet access when needed. It’s one of many features that set Crossfly apart.

Underwear may be the foundation of your outfit, but socks matter too. Our collection of socks for men includes designs that stay put, reduce odour, and keep your feet dry all day. Whether you're heading to the gym or the office, you'll find options tailored to your lifestyle.

Crossfly underwear is built for comfort, performance, and everyday ease. Whether you’re looking for enhanced testicular support, breathable fabrics, or all-day freshness, we’ve got you covered.
