A cork jacket refers to a buoyant garment specifically designed to provide buoyancy and safety to individuals in water, particularly in aquatic activities like swimming, boating, and other water sports. It typically consists of a jacket-like structure, commonly made of lightweight and durable materials such as nylon or canvas, which is filled with rows of small cork blocks or panels. These cork blocks or panels are strategically placed throughout the jacket to ensure maximum buoyancy and flotation.
The purpose of a cork jacket is to prevent the wearer from sinking or losing consciousness in water by keeping them afloat. The cork blocks or panels inside the jacket provide the necessary buoyancy to counteract the weight of the individual, effectively keeping them on the water's surface. This ensures that the wearer can remain in a position that allows them to breathe and reduces the risk of drowning in the event of accidents or emergencies.
Cork jackets are often equipped with adjustable straps or buckles to ensure a secure and personalized fit for the wearer. They are commonly used in water-related activities where there might be a higher risk of accidental immersion or when individuals may require assistance in staying afloat, such as in open water swimming, fishing, or basic water survival situations. It is crucial to wear a cork jacket as a precautionary measure and adhere to safety guidelines to ensure the wellbeing and welfare of oneself and others in water environments.

The word "cork jacket" can be broken down into two components: "cork" and "jacket".
"Cork" refers to a material derived from the bark of the cork oak tree (genus Quercus subser. Cerris). This material is buoyant, lightweight, and waterproof. It has been used historically for various purposes, including as a flotation device for boats, fishing nets, and life-saving equipment.
A "jacket" typically refers to a type of outer garment worn on the upper body. It provides protection and insulation from the weather.
Therefore, a "cork jacket" is a type of jacket made with a layer of cork or filled with cork material. It was primarily used as a buoyant and protective garment for individuals engaging in activities near water, such as sailors, fishermen, or swimmers.
