When Nature Says Stop

Zerofit base layers provide maximum warmth with minimal restrictions.

zerofit fabric technology

Twice as warm as a sweater

Zerofit Ultimate keeps you warm by way of a unique mix of five fibers and a patented knitting process. The extra-long fibers on the inside, gently rub against your skin to create frictional heat.

Heatrub Move

Say goodbye to cold sweat!

The MOVE gives you instant heat with zero sweat too! It has a cooling two-layer construction which moves moisture from the body to the outer shell fabric where it dries ultra-fast.


I really liked the ZeroFit Heatrub baselayers as they did everything that they claimed they could. Both felt lightweight and didn't restrict my movement, they definitely did a good job of keeping me warm, and the fact that they were relatively water resistant was also a nice bonus. The samples I tried were pretty plain- black and grey- but I've seen a couple of other colour options including red and navy too so you can match up with the rest of your gear you usually wear.

You have to be spending a good bit of time in pretty much one location, and just by standing still, you will feel the cold. And that’s when the Zerofit comes into its own – because you just don’t get cold wearing it, it’s brilliant stuff, incredible. I was covering a Championship football match for Getty back in February, and it was sub-zero. Obviously, you’re checking the temperature on your phone, so you make sure you’re properly attired before heading out, but when I was out working it never felt anywhere near as cold – and that’s because I was, possibly for the first time in my career, wearing suitable clothing.

The Ultimate line delivers the warmth needed for the Mid-Atlantic winters and lives up to its name. Zerofit brand may be new to the US market and may require a little leap of faith because you probably cannot find it in stores, but those who are willing to take the leap will certainly find high performing clothing for cold, cold mornings.
