Firstly, the inflatable lifejacket is extremely buoyant. By inflating the air bladder, it provides higher buoyancy than a traditional foam lifejacket, enabling the wearer to easily remain above water, which is vital for rescue and self-rescue. This high buoyancy design ensures that the wearer can quickly gain buoyancy support in an emergency and avoid sinking to the bottom of the water.

Secondly, the inflatable lifejacket is designed to be lightweight and fit snugly. When uninflated, it is small and not bulky to wear, which allows the wearer to be flexible during a variety of water activities. At the same time, modern inflatable lifejackets are usually equipped with a variety of adjustments, such as shoulder straps and waist belts, which can be adjusted to suit different body types, providing better comfort and stability.

In addition, inflatable lifejackets can be inflated in a variety of ways. There are both automatic inflation devices and manual inflation methods. The automatic inflation device can quickly inflate the lifejacket when it touches the water, reducing the complexity of manual inflation and improving safety. Manual inflation is suitable for safer waters and boats, and the buoyancy can be adjusted as needed.

Finally, the inflatable lifejacket is also equipped with a variety of additional features, such as reflective tape, whistles, signalling lights, etc. These features improve the wearer's visibility and chances of being detected in emergencies, and enhance the success rate of rescue.

In summary, inflatable lifejackets have become an important safety guarantee in water activities due to their high buoyancy, lightweight and comfortable, flexible and diverse inflation methods, as well as a variety of additional features.
