We Believe In Innovation

 Improving Male Underwear and Sportwear:
Our Patented Design. Ergonomically cut to suit the male body shape, creates comfort through natural body alignment. We are improving performance in your sport through innovation.

Amazingly, male underwear design hadn't changed much in a hundred years. Jacob Golomb first introduced boxer shorts in the 1920s when he had the nifty idea of using elastic around the waist rather than a leather belt (as used by real pugilists at the time). Briefs and Y fronts followed soon after in the 1930s.  Back then stretch fabrics like microfibe and modern sewing machines hadn't been invented. Garments were simply sewn together in straight lines to form the traditional boxer shorts and briefs that we know today.   



 Cahoonas: Why we're Different 

Since those early days, fabric and sewing technology have taken a massive leap forward but, until now, no designer has ever considered one startling fact: that 75% of men dress to the left and 25% dress to the right.  This is no urban myth but a medical fact discovered in the 1960s as part of a wider research programme.  

With the 'one size fits all' concept seriously out of date, we decided to challenge ourselves to creating a new, ergonomic design. One year of research and development later, the Cahoonas 75 Trunk was born.  

Put simply, our 75 Trunk takes into consideration whichever side you dress for a more ergonomic, comfortable fit.  It physically creates a partial sphere in the crotch area, curving its way round from below the testicles and guiding the penis towards the correct and most comfortable side of your body. By allowing the penis to rest in its naturally preferred direction of dress - without overt compression - you inevitably reduce the need to re-adjust yourself during sport and everyday activities.  Our design is now fully patented and is one of the biggest single advances in male underwear design since the 1920s. 

It's not just underwear where you can feel the difference, but in sportwear too as we've used our patented design to develop a range of sports base layers that will add to your comfort - and therefore your performance.
