ZeroFit Fabric Technology

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

ZeroFit USA proudly brings you Zerofit – the Japanese brand of base layers made using a unique and advanced Zerofit fabric technology. Just like many Japanese products, Zerofit ensures and prioritizes quality and functionality over cost. It affords you comfortable and top-grade base layers right within your reach.

What Makes Zerofit Fabric Technology Unique?

Zerofit engineers create products that boost comfort and mobility using specially designed fabrics. With Zerofit fabric technology, these five products with their unique features came to fruition:

  • Heatrub Ultimate – The traditional base layer that seals in body heat so it becomes warm instantly. What’s even more impressive is that the unique fibers of this garment enable you to create frictional heat. Lastly, the four-way stretch fabric allows more movement than its more common base layer counterparts permit. All these benefits contribute to it becoming the flagship product of the Zerofit line.
  • Heatrub Move – Looking for a Zerofit product with the most versatility? Move provides this to you while allowing you to stay warm. The fabric used has a 2-layer construction that promotes moisture-wicking, moving moisture away from the body, making it the best choice to wear during sports activities like hiking, running, hunting, fishing, golf, baseball, or soccer.
  • Cold Skin – Do you need to protect yourself from harmful ultraviolet rays while joining active sports or other activities under the sun? If so, you’ll want to wear this base layer as it provides UPF50 (50+ ultraviolet protection factor, which is the maximum rating a fabric can have.
  • Thermoweave – This product enables fluid body movements with the 500% stretch afforded by the fabric used for this Thermo Weave.

With ZeroFit USA, products designed with the Zerofit Fabric Technology are now available throughout the United States. Get the best protection and versatility possible when you buy our products. For questions or orders, contact us here or shop here directly.
