ZEROFIT Men's Ultimate Heatrub Long Sleeve, Grey, XXL

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. 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.
