But there’s one material that keeps surprising me – not just for comfort, but for safety. Merino wool. In 2022, The Woolmark Company published a technical report on wool’s natural flame-resistant properties. It confirmed what many of us in manufacturing had already seen on the shop floor: wool behaves differently than cotton or synthetics when exposed to fire. If you’re designing protective clothing for firefighters, military personnel, or even F1 drivers, this matters more than you might think. Why Wool Stands Out in Fire Safety Let me put it simply.

Polyester definitely doesn’t. For close-fitting base layers, that difference can save lives. Six Technical Reasons Wool...
