Heatrub Ultimate Baselayer - Navy

Zerofit most popular baselayer across the entire collection, the award-winning Zerofit Heatrub Ultimate is a best-in-class, game-changing baselayer that has been independently tested and proven to be five times warmer than leading competitors, and twice as warm as a sweater.

Technologically enhanced 'Heat Threads inside the garment are activated through even the slightest of movements, gently brushing against the skin to generate positive warmth instantly and the construction of the Zerofit Heatrub Ultimate means the heat is retained.

Unlike other baselayers, the Ultimate does not work on the basis of 'compression for heat' - so not only does it provide greater warmth, but you also won’t feel restrained by an inability to move freely, making it one of our most comfortable baselayers.

It also features a slightly looser neckline design, which allows some heat to travel out away from the body - during testing and development of the Ultimate, a tighter neckline was found to cause some overheating.

A rigorous product evaluation at the iconic Boken Institute Japan's leading testing organization resulted in a Heat Retention Rating of 0.78; a standard baselayer would have a rating of 0.1-0.14, while a sweater would typically have a rating of around 0.3.

Regardless of whether your passion is fishing, hiking, motorcycling, golf, equine sports, sailing, skiing, gardening or you spend a great deal of your working day outside the Ultimate has got you covered in temperatures as low as minus 10° Celsius.

And because it's so good at keeping you warm, there's no need to 'layer up' with bulky additional clothing - the Ultimate does the work of multiple layers which also makes it a cost-effective heating solution.



Key Features:

  • Independently tested and proven to be five times warmer than a standard baselayer
  • Instant heat the moment you put it on, doesn't require compression/tightness to keep you warm
  • No need for multiple additional layers due to the warmth generated by the innovative Heat Threads on the inside of the garment
  • Incredible freedom of movement due to the stretchable nature of the fabric.
