When purchasing the Heatrub Ultimate or the Heatrub Move baselayer please note that due to the fabrics used and the manufacturing process for each garment, the Ultimate comes up slightly smaller than the Move.


Both products are designed for a snug but not overly tight fit, and the stretch properties of the fabrics in the Ultimate and Move allow the user to move freely, whatever their sport or activity.

NB: For other products sizing is shown below.


The new Thermal Bobble Hat has been developed in Japan with insights from the same innovation team that created the award-winning Zerofit Heatrub Ultimate baselayer, and it’s now available in the UK, Europe and North America for the first time.

The Thermal Bobble is the perfect accessory to complete your cold weather wardrobe and combines with The Ultimate Baselayer and Leggings in temperatures as low as -10° Celsius, making it perfect for winter hiking, walking, fishing, sailing and golf.

It’s also a stylish product for day-to-day activities such as dog-walking and taking the kids to school, and it comes in an eye-catching Jet Black colourway, adorned with the brand logo of Zerofit – The World’s Warmest Baselayer®.
