Key Technology

1 Innovative ‘Heat Threads’ positioned on the inside gently rub against the skin as you move, which creates positive warmth across the body.

2 A standard base layer traps body heat between the skin and the material, so it takes a little time for the user to feel the benefits. On the Zerofit Ultimate, five separate fabrics, along with a patented knitting process, create instant warmth as soon as you put it on.

3 The unique fabric mix means you don’t need tightness to activate warmth, making it more comfortable. Available in five colours.
