Does a Wool Blanket Perform Well When Wet?

Wet Performance of Wool Blankets

Wool blankets are often marketed as a versatile and durable option for outdoor enthusiasts. However, when wet, wool loses its insulating properties due to the absorption of water. This can be attributed to the fact that wool fibers swell and lose their ability to trap warm air, reducing the blanket’s effectiveness by up to 70%.

Insulation Comparison: Wool Blankets vs Sleeping Bags

When comparing the wet performance of wool blankets to sleeping bags, it becomes clear that sleeping bags are a more reliable option. Sleeping bags typically use synthetic insulation, such as polyester or nylon, which retains its insulating properties even when wet. For example, the Polarguard 3D synthetic insulation used in many sleeping bags retains 90% of its insulating properties even when wet. In contrast, a wool blanket may lose up to 70% of its insulating properties.

Durability and Weight Considerations

Wool blankets are often heavier and less durable than sleeping bags, which can be a significant consideration for backpackers and long-distance hikers. A wool blanket can weigh up to 3 pounds (1.4 kg), while a sleeping bag can weigh as little as 1 pound (0.45 kg). Additionally, wool blankets may require more maintenance and care, as they can be prone to pilling and snagging. When comparing the wet performance of wool blankets to sleeping bags, it’s clear that sleeping bags are a more reliable and practical option for outdoor enthusiasts.
