"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."

What reviewers say
AI generated
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.

I bought a Move Shirt at the Carlsbad street fair. I was pleasantly surprised at how much warmth is generated by such a thin and light layer. It is essentially replacing my lightweight down vest during a chilly sunset. I like it a lot and plan to buy another one.

Great review Tony, thanks for your time.. Stay warm
Order arrived before stated time. Initially I thought the base layer might be too tight but I decided to keep it and used it on a recent golf trip that was cold and windy. The base layer kept me remarkably warm and I never felt constricted. It’s a great product.
I worked with Dave in customer service on a return. Great service very helpful. Nice to still talk to a real person that cares about their company and products. Thank you so much for working with me.

Thanks for the kind words, by the way my name is Doug. LOL
I purchased the Heatrub Move(Mock) and the Heatrub Move Unisex Hoode at the South Coast sportfishing show in Costa Mesa.
I go on the charter sportfishing boats out of Berkeley marina near San Francisco.
I wore both Heatrub Move and the Heatrub Hoodie over my tee shirt last weekend. There was a breeze and I was nice and warm. I wore my light weight windbreaker jacket over the two Heatrub's. I bought XXL size and tried them on at the show and thought they were too tight, but after I put them on and wearing them for a short while, they both stretched and became comfortable. One of the best things I have bought to add to my fishing attire. Very light weight and I can move around them easily.

Fantastic review Don, great meeting you and I hope you catch a bunch of fish. Stay warm
This is my first purchase of Zerofit Heatrub Ultimate Unisex Base Layers. I've used them on winter motorcycle rides and I am impressed. I was comfortably warm the entire ride.
Customer Service is the best! I mistakenly ordered the wrong size on one of the items and Zerofit sent a replacement before I even had a chance to return the original! That is truly excellent Customer Service

Fantastic review George, please spread the word about Zerofit... Thanks
My order was filled, shipped and received very quickly and correctly -with a 100% Customer Satisfaction Guarantee. To have confidence in your product and service like that -you gotta KNOW you have the good chit!! Now that I've doubled up on my multiple layers -it's ridiculous how often I wear ZeroFit. Pretty much all the time -love it for it's fit, feel and performance!!

Thanks James, I love hearing these reviews. Please spread the word about Zerofit and the service... Thanks again
Figured I give these socks a try. Always looking for something to keep feet warm. Didn't find them to be any different from the socks I normally wear. Not sure how to rate them as they are just a thicker heavier socks! Would I but them again? Don't need expensive socks that work and feel as comfy as socks I already wear and find much cheaper elsewhere!!

Sorry to hear that Tim, everyone raves about how good they are...
Hat is terrible. I have not tried the base layer or the socks yet but I did try the beanie cap. This is an extremely bad design. The insulative layer is very very short. It should extend 2" lonter (5cm). Needs to provide more coverage for the ears and forehead. Please improve the design before the next production run.
Great doing business with you folks. I bought the wrong size at Portland sportsman’s show. Dave gladly e mailed me a return sticker and sent replacements that day. Thanks guys. I did get a chance to try them on a ski day. They worked well maybe to well I wasn’t cold and that’s what counts!

Thanks Clancy for the time to give us a review, stay warm
I was introduced to the products at the Portland Sportsman show. I first thought they were just another base layer, but after some thought I ended up purchasing the ultimate base layer top and bottom as well as the heart rub parka. I figured I’d give them a shot. I work outside and need something that will keep me warm. The next day I had them on and I was toastie. It snowed that day and was in the mid 20’s. Boy was I glad to have purchased this product! I have other base layers but these are the best for really cold weather! They will do well when I go fishing in the Spring and Fall in the cold and rain I’m sure. I was so impressed with them that I purchased a top and bottom ultimate base layer for my wife. Thank you. You made me a believer!!!
