"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."

Sadly, I don't own a bike but still find my v-neck short sleeve base layer to be beneficial to keep my hot body comfortable. Works so well I purchased another, in long sleeves. When the weather get's cold, I'll be stocking up on gear more fitting to very cold weather.

I didn't notice any cooling benefit. Brought a regular t-shirt on my ride (motorcycle) to compare and I believe I felt cooler in my regular t-shirt - wore both under a vented motorcycle jacket. Very disappointed, is it possible to return for a refund?

It's a nice product; however, they are sized smaller than expected. I got the biggest size available and it is very very skin tight.
