The higher the CLO value, the higher the amount of warmth a piece of clothing provides.To determine temperature ratings, CLO factors, Metabolic Equivalent of Task (MET) and the time or duration of a task are considered. MET levels are categorized into 3 groups:“Low” range (0-3 MET) // forklift driver, equipment operator“Moderate” range (3-6 MET) // picking & packaging, delivery drivers“Vigorous” range (>6 MET) // concrete work, tower climber Some warehouses and facilities are more manual in nature, leading to higher MET levels, while others rely on automation, resulting in lower MET levels.
