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.

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.

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. And since November 2023, Bennetts British Superbikes Runner-Up Glenn Irwin has joined the brand as an ambassador. Relying on our product for the 2024 season, he became the most successful rider in the history of the iconic North West 200 road race, before retiring from that arena.

Scott Redding became the brand's first WorldSBK rider when he came on board ahead of the 2025 season, and Zerofit will have more than 35 riders in the Bennetts BSB Championship wearing our award-winning products.

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.
