Quick Answer
Wool blanket is a better choice for survival due to its versatility, ability to insulate when wet, and durability. It also provides warmth without being too heavy, making it ideal for backpacking. However, a sleeping bag is more convenient for sleeping.
Durability and Versatility
A wool blanket is an excellent choice for survival due to its durability and versatility. It can be used as a blanket, a ground cloth, or even a makeshift shelter. A wool blanket can withstand harsh weather conditions, including rain and snow, without losing its insulating properties. In contrast, a sleeping bag is designed primarily for sleeping and may not provide the same level of protection in wet conditions.
Insulation Performance in Wet Conditions
Wool is a natural insulator that retains its warmth even when wet. A wool blanket can maintain its insulating properties up to 30% even when soaked in water, making it an excellent choice for survival situations where rain or snow is a possibility. In contrast, a sleeping bag may lose its insulating properties when wet, making it less effective in harsh weather conditions.
Weight and Portability
A wool blanket is generally lighter and more portable than a sleeping bag, making it an excellent choice for backpacking and long-distance hiking. A wool blanket typically weighs between 2-4 pounds, while a sleeping bag can weigh anywhere from 3-6 pounds or more, depending on the model and features. This makes a wool blanket a more practical choice for survival situations where weight and portability are critical factors.
