 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With the 'one size fits all' concept seriously out of date, we decided to challenge ourselves to creating a new, ergonomic design.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.

    The Cahoonas 75 trunk is also a sports underwear garment designed to be used as a base layer for training.
    The benefit of microfibre is that it exerts an equal level of compression to the upper thighs and buttocks while improving blood flow and enhancing lymphatic drainage.
    • Made in Britain by properly-paid, skilled machinists

    • Enhanced fit and performance characteristics including four-way stretch and fully breathable fabric 

    • Inherent temperature-regulating qualities in both hot and cold conditions. For instance, in the cold, microfibre will help keep your muscles warm. Conversely, in the heat, microfibre will wick moisture away from your skin to cool you down

     Garment Testing
    We've road tested our garments in all kinds of places and in all situations. We've jogged, sprinted, fought, cycled, climbed and back-flipped them through their paces and comfort-tested them on trains, planes and automobiles and in offices, gyms and boxing rings both here in the UK and more tropical climates. In fact, we have a Cahoonas-tester travelling through Cambodia right now because obviously trekking through jungles, scaling temples and busting moves on boat parties are the perfect testing parameters.

     Key Features


    Remember to switch off their lights, 

    before you leave the ring. 

    After a year of research and development we finally launched our FightFixer sparring gloves.  Designed with the help of professional boxers, you won't find any other gloves like this on the market.

    Respect Fightfixer Boxing gloves poster Lace up Sparring gloves made with 100% breathable, cow hide leather, FightFixer comes in white for improved sparring visibility.  

    Technical innovation: 
    Improved visibility means Improved reaction time which in turn improves ability to respond to a punch:

    Result you win more Fights.

    How so? Well, scientific tests show that your peripheral vision isn't suited to viewing colour (the colour receptor cones in your eyes can't detect colours efficiently).  However, with our white and black design, detection is faster (and easier on your eye) for improved sparring.

    Professional boxing gloves We've also avoided stitching labels on the outside of our gloves. Why? Labels stitched on the outside of gloves create a raised surface edge that can cut your sparring partner from a glancing blow. So what else can you expect? FightFixer sparring gloves have a 3 layer energy dissipation system:

    Layer 1 Respect
    A dense outer impact foam layer delivers the respect you deserve.
    They’ll know they’ve been hit and they’ll feel how hard they’ve been hit.

    Layer 2 Power
    Advanced energy dissipation foam layer maintains punch force, while avoiding
    concentrating impact damage.

    Layer 3 Protect
    Multidensity fist protection foam layer, increases energy dissipation and protects fist.

    Not only that but these new gloves look the bomb and are part of our new FightFixer combat range - a superior range of boxing and MMA fight equipment and kit.

    Train hard, fight easy: we've all heard that one before but training can only take you so far. Technique and performance kit are just as important in the world of all sports. The right sort of protection during training sessions means you'll still be fighting fit when it comes to the big fight and that's what we believe here at Cahoonas. Which is why, with the help of professional fighters, we're continually developing the FightFixer advanced and pro-fighter range. So, if you love a good fight as much as we do, the chances are you’re probably training or are familiar with one or more of the following fighting styles:

    Mixed Martial Arts (Freestyle Fighting)



    Brazilian Jiu-Jitsu 



    Krav Maga

    Kung Fu



    Muay Thai



    Sanda Indochinese Kickboxing
