"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."

Reviewers overwhelmingly had a great experience with this company. Many customers frequently share that the base layers are exceptionally warm, well made, and keep them comfortable during cold weather activities. Consumers also love the overall quality of the items, noting that everything performs wonderfully just as advertised. People often mention the easy ordering process and the surprisingly fast delivery times that exceed original expectations. However, some customers also noted that certain items, particularly the bottoms, can run smaller than expected and require careful sizing. A few reviewers mentioned needing to exchange a couple of pieces for a better fit.
Auto-generated from all reviews of this business. For reference only.Game changer for South FL heat. I admit, I was skeptical. It gets really hot in the Treasure Coast in South FL and I’ve tried quite everything to keep cool under gear. Took a solid two hour ride over the weekend in mid August. It was the first time I can recall coming back from a ride like that this time of year not a complete dripping sweaty disaster. Order one now.
THanks for the revIew
Zero Fit did an awesome job of getting my product to me quick. It was my birthday present from wife. Does its job in Hot Texas football weather! Just wish they had more options for summer in stock.
FantastIc revIew, yes It can get hot there In TexasI!
The site is easy to navigate. The products ordered performed as described. Ice mesh top and bottoms kept my commute to work chill in ninety degree heat in California. Although some items were sold out in my size, I hope they will restock soon because I want to order more. Thanks again for such a great product.
Thanks for your tIme
It works! The only thing I would change is to make the collar a little taller/higher on the neck.
Thanks, ride safe
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.
We will be waiting for you! Stay cool
Yes you need to size up like it says on the website. Sorry about that
Nothing really wrong yet except I haven't received it.I hope he shows up in the next fifteen days.I'm leaving on a big european vacation.
You will
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.
Thanks for your time
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?
Already took care of you, sorry you feel that way
Absolute game changer. I was skeptical at first. But this shirt works as advertised. Buying 2 more asap. Thank you Zerofit
Love it, stay cool
Straight forward ordering process, quick delivery and a great product.
Great to hear
I have always been fully satisfied with your products and I’m glad you introduced the V-Neck Mesh version! Thank You!
Love it
The shirt I ordered was out of stock. I got a call from Doug, he asked if he could substitute for a different, more expensive style, at no extra charge. Fast shipping, great product. Can't wait to try it out on the track this weekend!
Your welcome

Great to hear that. Thanks

Socks are great, haven’t tried top yet
Thanks for the review
Fits well but real trial comes with colder weather

Purchased long-sleeved IceMesh top. First size I ordered did not fit me. Reordered larger size and now... A Great Fit! It is a very nice product and I am happy!
Glad we could help you out, ride safe
