Zerofit is a Japanese specialist baselayer brand which was founded by Mr Koji Higashi in 2005. It launched in the UK and Europe in 2018 before further expansion into North America in 2020 and Australasia in 2021.
The award-winning Heatrub Ultimate baselayer was unveiled to the Japanese public in 2011 and since then hundreds of thousands of outdoor enthusiasts have discovered the benefits of that best-in-class product. Independently tested and proven to be five times warmer than a standard baselayer, the Heatrub Ultimate has become a must-have item in the coldest months of the year and, such was the popularity of the baselayer, Zerofit now offer leggings and socks made from the same material, with waterproof gloves and mittens also available for complete protection against the elements.
Other key products include the Heatrub Move baselayer, which features Adaptable Warmth Technology, keeping you warm while at a standstill but also temperature regulation when you’re working up a sweat. For the summer months, the Cold Skin baselayer is three times colder than a competitor product, while the Ice Weave is the master when it comes to wicking excess sweat in the hottest conditions. Motorcyclists have discovered the astonishing performance of the IceSkin baselayer, which offers cool contact performance and optimal moisture wicking in the hottest of conditions.
Following exponential growth across industries including motorcycling, angling, running, hiking, sailing, golf, gardening, birdwatching and equestrian sports, Zerofit welcomed a new shareholder and ambassador in February 2023 - Brian O'Driscoll, the former Leinster, Ireland and British & Irish Lions rugby captain in order to help further enhance the business across multiple categories.
Zerofit is the proud supplier of baselayers to more than 80 elite motorcyclists in the bennetts BSB Championship, WorldSBK, North West 200 and the Isle of Man TT. The likes of Glenn Irwin, Scott Redding, Peter Hickman are just three of the best to rely on our baselayers for complete comfort and performance.
In April 2025, acclaimed broadcaster and adventure rider Charley Boorman joined the Zerofit brand as an ambassador.
The European HQ of Zerofit is in County Antrim, Northern Ireland, with further offices in Adelaide, Australia and San Diego in the US. Specialist customer service teams in each country ensure prompt and accurate delivery of products as the brand continues to grow globally.
Whatever your sport or activity, we hope Zerofit will become your baselayer brand of choice.

Charley Boorman
Acclaimed broadcaster and adventure rider Charley Boorman joined Zerofit as brand ambassador in April 2025. Best known for his epic long-distance motorcycle journeys, Charley has ridden some of the most demanding terrain on the planet — and knows better than most what it takes to stay warm and comfortable on the road.
Ali Hamidi
TV presenter, carp fishing legend and one of the most recognisable faces in British angling, Ali Hamidi has been a Zerofit ambassador since the brand launched in the UK. A man who spends more time on cold lakesides than most, Ali's endorsement of Zerofit isn't a contractual formality — it's the product doing exactly what it's designed to do.
Brian O'Driscoll
Former Leinster, Ireland and British & Irish Lions rugby captain Brian O'Driscoll became a Zerofit shareholder and ambassador in February 2023. One of the greatest rugby players of all time, Brian's involvement goes beyond ambassadorial — as a shareholder he has a genuine stake in the brand's continued growth.
