Zerofit Ultimate Heatrub Baselayer LS Black

The Zerofit Ultimate Heatrub base layer long-sleeved top is made from Acrylic 68%, Nylon 21%, Polyester 2%, Wool 7% & Polyurethane 2%, with an optimal temperature range of -10° Celsius to 10° Celsius. It is independently tested and proven to be five times warmer than a standard base layer. Instantly heats the moment you put it on, doesn't require compression/tightness to keep you warm and no need for multiple additional layers due to the warmth generated by the innovative Heat Threads on the inside of the garment. It also offers incredible freedom of movement due to the stretchable nature of the fabric. 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 base layers, 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 base layers. 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.
