How are Class II harnesses categorized?

Class II harnesses are categorized specifically as "semi-full body harnesses." This designation indicates that the harness provides support around the waist and some coverage over the torso, typically incorporating leg loops that help distribute forces in the event of a fall while allowing for some movement and flexibility.

The semi-full body design is especially important in various rescue and climbing situations, as it helps keep the person's center of mass aligned and reduces the risk of inversion during a fall. This is particularly relevant for situations in which users may need to suspend themselves or perform tasks at height.

Belt harnesses, while used for certain applications, do not provide the same level of support or fall protection as semi-full body harnesses. Sit harnesses are a specific type of harness used primarily for seated positions in climbing or work systems, and lightweight harnesses refer more broadly to harnesses made from lighter materials but do not specifically align with the Class II categorization. Understanding these distinctions is crucial for selecting the proper harness for different rescue and climbing scenarios.
