ZEROFIT Mens Heatrub Ultimate Baselayer - Green - L

Material: Acrylic 68%, Nylon 21%, Polyester 2%, Wool 7% & Polyurethane 2% Optimal Temperature Range: -10° Celsius to 10° Celsius 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. 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.
