Because we think men’s underwear can do better.

Crossfly combines patented technology, smart design and premium materials to solve the everyday frustrations that traditional underwear often overlooks.

From our X-Fly® easy-access feature and ZeroFold360™ waistband to our Coccoon internal support system, every detail has a purpose — delivering comfort, support, freedom of movement and convenience.

It’s not underwear for the sake of underwear. It’s underwear engineered around how men actually liv with technologies that make sense.

Yes. Comfort is central to Crossfly’s approach to men’s underwear. Just read our reviews and see what other customers are saying about us.

Crossfly is designed to provide support without restriction, with breathable fabrics and intelligent construction that help your underwear stay comfortable throughout the day.

Our Coccoon internal support system provides breathable separation and helps reduce friction, while the ZeroFold360™ waistband is designed to stay comfortably in place without unnecessary rolling or adjustment.

The X-Fly® is Crossfly’s signature easy-access underwear feature. It is designed to provide convenient access without requiring you to pull down the waistband or significantly adjust your underwear.

For guys of a certain age, going to the toilet quickly can become a focus and with Crossfly's X-Fly easy access; you can go from 0 to 60 in 1.2 seconds!

It is one of the features that distinguishes Crossfly from traditional men’s underwear and is designed to make everyday use more convenient. Because X is the new Y.

The ZeroFold360™ waistband is a Crossfly waistband technology designed to provide a comfortable, secure fit around the waist.

All our waistbands have gone through vigorous testing ensure they are sturdy without discomfort. Its construction is intended to minimise folding and rolling while helping the underwear stay comfortably in place during everyday movement.

The Coccoon is Crossfly’s internal support system, designed to provide breathable separation and help reduce friction.

By creating a more structured internal environment, the Coccoon is designed to keep everything comfortably supported and separated rather than compressed together. This can be particularly useful during long days, periods of increased movement and physical activity.

Yes. Crossfly offers underwear specifically designed for active lifestyles through its Performance Series.

Performance-focused men’s underwear is designed with movement, support, breathability and friction reduction in mind, making it suitable for activities such as training, running, gym sessions and other sports.

Yes. the Coccoon support pouch is designed to provide breathable separation and help reduce unnecessary friction.

That matters whether you’re sitting at your desk, walking around all day or pushing yourself during a workout. Less friction means less distraction, so you can get on with your day.

It’s one of the ways Crossfly takes a different approach to men’s underwear — designing the inside as carefully as the outside.

Crossfly predominantly uses TENCEL Modal for its underwear range. All the Everyday series uses Modal while the Performance series uses a nylon blend for better performance qualities (Sweat wicking, semi compression).

Modal is a regenerated cellulose fibre commonly valued for its smooth texture and moisture-management properties, making it well suited to next-to-skin clothing such as men’s underwear.

We believe better underwear should feel good in every sense. That’s why our Everyday Series uses Modal — a soft, breathable fabric made from regenerated cellulose fibres and chosen for its comfort and sustainability credentials.

We’re always looking at better materials and smarter ways to make underwear that works harder, while being more considered about what goes into it.

Absolutely. But for us, premium isn’t just about how it looks.

It’s about how your underwear feels at 6am, how it performs at 6pm, and whether you forget you’re even wearing it. Our customers say it best "It's like wearing nothing"

Crossfly combines innovative design, premium fabrics and patented technology to deliver the comfort, support and freedom of movement modern men actually need.

That’s exactly what it’s designed for.

Whether you’re at your desk, on the move, travelling or on your feet all day, Crossfly is built to stay comfortable and supportive from morning to night. In hotter climates, Crossfly performs well for its breathability and sweat wicking qualities.

Our Coccoon internal support system helps keep everything comfortably separated, while the ZeroFold360™ waistband is designed to stay put without digging in or constantly needing adjustment.

Because your underwear should work all day — not become something you have to think about.
