6. Functional criteria for building a 72-hour self-sufficiency kit The success of a 72-hour self-sufficiency kit lies in its ability to be both functional and flexible. Therefore, we distinguish between fixed components and adaptable components.Fixed components are those essential and universal, regardless of geographical or climatic context. They include: water and basic food, a first aid kit, emergency communication tools (radio), a light source (headlamp), basic tools (multi-tool knife), and emergency thermal protection (thermal blanket). These elements form the indispensable core of the kit. Adaptable components are those that can and should be customized based on various factors: • Geographical context: In mountainous areas, for example, warmer clothing or equipment for difficult terrain might be necessary. In coastal areas, there might be a greater focus on moisture protection. • Climate: The season directly influences clothing and the need for more or less insulating sleeping modules.
