Wool is a valuable material for survival and outdoor activities due to its unique properties. It retains warmth even when wet, offers superior breathability compared to synthetic materials, and resists fire damage. However, it is heavier and bulkier than alternatives like down or polyester fleece. Practical recommendations include wool socks (e.g., Wigwams), thermals (e.g., Minus33), and blankets (US Military Issue). The Boreal Shirt, made from 100% wool US Army blankets, is highlighted as a durable, multipurpose piece of gear. While wool may be more expensive and scratchy, its advantages in temperature regulation and durability make it a strong choice for long-term use in variable climates.
