Bent back and forth repeatedly, a strand of polyester fiber will snap after approximately 3,000 bends. By comparison, Merino Wool is more than six times as durable, breaking only after it’s bent roughly 20,000 times. The choice is simple for the savvy investor in fine outdoor clothing.
Merino Wool is flame-resistant to boot. Its inherent fire resistance is derived from its naturally high nitrogen content. Because of this natural rarity, Merino Wool requires higher levels of oxygen in the surrounding environment in order to burn. Our wool may be ignited if subjected to a significantly powerful heat source, but it does not support flame easily, smoldering for short periods instead–and usually only for a short time. Even more remarkably, Merino Wool’s cross-linked cell membrane structure will swell when heated to the point of combustion, forming an insulating layer that prevents the spread of flame. This also means Merino Wool produces less smoke and toxic gas than synthetic fibers when in contact with an open flame. For campfire aficionados, Merino Wool is the sensible choice.
