Life jackets are designed to keep people afloat in water and prevent drowning. The manufacturing process of life jackets typically involves cutting the pattern in the nylon, cutting the foam (depending on the model), and finally assembling the pieces by sewing them together. The interior of a life vest is made of plastic foam such as polyvinyl chloride or polyethylene . The outer shell of the life jacket is typically made of a nylon or vinyl material.

There are three different classifications of life jackets: inflatable, inherently buoyant, and hybrid. lnherently buoyant life jackets have the flotation power built-in, while inflatable life jackets need to be filled with air . Hybrid options involve both natural buoyancy and manual inflation.

Previously, cork, balsa wood, or kapok (a material from a tropical tree) were used to make inherently buoyant life jackets. However, these days, plastic foam is the most commonly used material for making life jackets.

Choosing a life jacket that fits you well is crucial for your safety. Here are some tips to help you choose the right one:
