Heatrub Ultimate Best Skiing– No Other Base Layer Is Made This Way!

Are you an outdoor enthusiast who does not want to be bothered by the cold? if so, the heatrub ultimate sking unisex base layer makes a great sports buddy for you whenever you are doing outdoor activities or sports. "Heatrub Sking base layer" is a baselayer designed for skiing or other cold weather activities. Not only does it ensure your protection from the cold, but it also allows unrestrained movement unlike other base layers in the market today.

Why Buy Heatrub Ultimate?

Here are the three benefits of having your own Heatrub Ultimate:

Instant heat

This base layer mock lends heat as soon as you wear it! The instant warmth is due to the unique mix of the following fabrics:

    • Acrylic (68%
    • Nylon (21%)
    • Wool (7%)
    • Polyester (2%)
    • Polyurethane (2%)

Heat Maintained

The leading skiing base layer in the market today utilizes 100% polyester.  This fabric requires time to seal body heat within it, thereby creating warm air. In contrast, the 5-fabric blend used for the Heatrub Ultimate Sking provides heat instantly. What’s more, the extra-long fibers create heat when they are rubbed against your skin, allowing heat to be maintained within it. In short, you feel warm the moment you put it on and remain warm while doing your usual activities.

Freedom of Movement

Aside from providing warmth during cool days, this heavyweight base layer is also designed to allow freedom of movement. With its patented knitting process as well as the incredible blend of five fabrics, you get a gear that is perfect for slower-moving and active sports. So, whether you like walking, hiking, cycling, football, snowboarding, gardening, biking, sking the zerofit ultimate unisex base layer is an excellent choice to wear.

Snowboarding Base Layer Essentials

In summary, this Zerofit base layer is an excellent gear for your coldest weather conditions. Wear it and be protected from the cold to freezing temperatures while doing the outdoor sports you love best.  With Zerofit USA, you can readily avail yourself of the authentic Heatrub Ultimate and more.

And with the rising cost of fuel and energy prices, many customers are telling us they are using Zerofit baselayers and our Performance Move Hoodie around the home too.


Zerofit founder Mr Koji Higashi created Zerofit because his passion and love of golf was not matched by products on the market that were supposed to keep golfers warm. The result? The most comprehensive collection of unisex baselayers to keep golfers out on the parkland, links and heathland courses all year long. The Zerofit Heatrub Ultimate baselayer won two Editor's Choice Awards 2022 in industry-leading publications Today's Golfer and Golf Monthly.

Feeling the cold while fishing affects concentration, performance and enjoyment of this great sport. That's why Zerofit products are designed to keep you by the riverbank or lakeside, on the sea or in the water for longer, and we are delighted to be an official partner of the sport's governing body, The Angling Trust, working together with them on content creation and helping anglers fish their favourite waters even in the coldest of conditions. Our award winning Heatrub Ultimate baselayer and Leggings have proven hugely popular, but we've also got toasty warm socks and lots, lots more.


Staying warm on the water, whether you’re racing or cruising, is something we all know the importance of.

Unisex Best Base Layer review
ZeroFit Heatrub Baselayers Review

I really liked the ZeroFit Heatrub baselayers as they did everything that they claimed they could. Both felt lightweight and didn't restrict my movement, they definitely did a good job of keeping me warm, and the fact that they were relatively water resistant was also a nice bonus. The samples I tried were pretty plain- black and grey- but I've seen a couple of other colour options including red and navy too so you can match up with the rest of your gear you usually wear.

The Zerofit Story

Zerofit was founded by Mr Koji Higashi in his native Japan in 2005 and the brand was launched in the UK and Europe in 2018 before further expansion into North America in 2020 and Australasia in 2021.

A passionate golfer and fitness enthusiast, Mr Higashi was unable to continue to do the sports he loved when the weather turned extremely cold, because he felt there was a significant lack of suitable clothing options to keep participants warm and their body temperature regulated.

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. Many products have been added to the extensive Zerofit collection over the years, including Heatrub Ultimate Leggings and the Heatrub Move baselayer, as well as products that are designed to cool users down in hot summer weather.

Whatever your sport or activity, we hope Zerofit will become your baselayer brand of choice.
