Introducing FreeTAN® with free FR technology from Muirhead.

Technological Breakthrough 

For over two decades, we have heavily invested in new initiatives to develop future-proof tanning systems without relying on chrome salts and glutaraldehyde. We have increased our aviation products' biodegradability and composability properties. We removed as many fossil-fuel-oil-derived components and heavy metals as possible without compromising technical excellence.  

Cutting-Edge Free FR Technology 

Muirhead FreeTAN® also maintains our status as the leading flame-retardant leather in the industry, regularly outperforming the industry standard by over 5 seconds in the Vertical Burn test. Our free FR technology is an efficient, environmentally friendly flame-retardant treatment refined through rigorous testing and years of development and is free of many harmful substances.

Comfort is of the utmost importance when travelling. That is why we subject all our products to rigorous testing to ensure they meet our customers' exacting standards for comfort and durability. By investing in Muirhead FreeTAN® or any other product from our range, you can rest assured that they will fly for a decade or more.
