When comparing sleeping bags, why is loft an important factor?

Loft is a critical factor in the performance of sleeping bags because it directly affects the insulation properties. The loft refers to the thickness and fluffiness of the insulation material, which plays a key role in trapping air. The more loft a sleeping bag has, the more air it can hold, providing better insulation and warmth retention. This, in turn, can significantly influence the weight and packability of the sleeping bag, making it easier to transport and carry for extended periods during various outdoor activities.

When selecting a sleeping bag, a higher loft is often desired for warmth, as it means better insulation without adding significant weight. On the other hand, sleeping bags with lower loft might be more compressible and lightweight but may not offer the same level of warmth. Therefore, understanding loft is essential for choosing a sleeping bag that meets your specific needs for comfort, warmth, and ease of transport during your outdoor adventures.
