Manpack → It is formed from "man" (from Old English "mann", meaning human being or person) and "pack" (from Old French "pac", meaning to pack or bundle). The word "manpack" refers to a bundle or pack that a person carries, typically used in military contexts for portable equipment.
Think of a 'person' ('man') carrying a 'bundle' ('pack') — that's why a manpack is a pack that a person carries.
