When buying a sleeping bag for camping and survival, consider:

            1.         Temperature Rating: Choose a bag rated for the lowest temperatures you anticipate encountering.
            2.         Insulation Type: Down offers excellent warmth-to-weight ratio, while synthetic materials perform better in damp conditions.
            3.         Weight and Packability: Consider the bag’s weight and how small it can compress for easy carrying.
            4.         Durability: Look for durable materials and construction suitable for rugged use.
            5.         Size and Fit: Ensure it’s spacious enough to sleep comfortably but snug enough to retain warmth.
            6.         Additional Features: Check for features like draft tubes, hoods, and zipper guards for added insulation and convenience.
            7.         Budget: Determine a reasonable budget while aiming for quality and features that meet your needs.
