ZeroFit Fabric Technology

No other base layer in the world is made this way!

Zerofit is the most technically advanced range of base layers in the world. Like many Japanese products, the first criteria is to ensure, without limit to cost that, the product works and function is at the forefront of all product development.

Zerofit engineers only launch a product that’s unique and better than anything else in the market. The flagship range of goes under the Heatrub name and the number one product is the Ultimate.

No other base layer in the world is made this way! A traditional base layer simply seals in body heat, however it does not generate heat. Not only does Heatrub seal in all that important body heat, it’s instantly warm and most importantly it creates its own heat due to the unique fibres inside the garment. It’s made with a four way stretch fabric so you get incredible freedom of movement too!

While the Ultimate is the most unique product in the Zerofit range, all the products have their own unique features. For example the Move uses 45% polypropylene to remove moisture from your body and keep you incredibly warm even during strenuous exercise such as running. The Cold Skin is cold to touch and ensures you stay comfortable even in the hottest of days. The Thermoweave is made from a mix of materials which provides 500% stretch so the fabric moves with your body better than any other base layer.

The list of our innovative, technicall advanced products continues to grow.
