"Mr Higashi launched the Zerofit brand in 2005, being a fitness fanatic, a single figure golfer and the owner of premium end Japanese golf hardware brand Giga he was constantly finding himself being cold while playing golf or doing more active sport such as running. Initially very technical active baselayer products were developed under the banner of ‘Smart warriors’. As the no 1 baselayer in Japan, Zerofit has only recently been made available for sale outside of japan. Zerofit successfully launched in the UK in Fall 2018 and is now launching in north america through our exclusive distribution partner ZF North America LLC, the only authorized wholesaler and on-line retailer of Zerofit in North America."

Having just moved to Virginia from California, I wanted to figure out a way to not stop winter from hampering my motorcycle riding. Enter Zerofit. I just bought the Heatrub Ultimate top, bottom and socks. Rode this weekend in 40F (feels like 32F) and I was comfortable even at highway speeds. Great product.

The ordering process was easy and the items arrived earlier than I had originally expected. The products are as great as advertised.

Fast delivery. Heatrub base layer is very warm. No need to wear a big coat over it in 20 degree F weather. Remember to order one size larger than normal. I plan to order gloves and a beanie also.

Fast, on time delivery even after exchanging because I ordered the wrong size. They immediately credited my account for the wrong size one that I ordered. And, to boot, the Ultimate Base Layer is exactly that -- ultimate. Easily the finest base wear I have now and I have some very fine merinos and ZeroFit beats them.
