It has enough buoyancy to be worn on the body so that the drowning person's head can stick out of the water.

1. Marine life jacket: This is also the most commonly used. It uses EVA foam material inside, which is compressed and 3D three-dimensionally molded, and its thickness is about 4 cm (the domestic production is 5-6 pieces of thin hair material, the thickness is about 4 cm) 5-7 cm), life jackets produced in accordance with standard specifications have their buoyancy standards, which are generally 7.5 kg/24 hours for adults, which means that adults' buoyancy can still reach 7.5 kg after immersing in the sea for 24 hours.

2. Self-inflating life jacket: This type of life jacket is commonly used for boat fishing. The interior is constructed of two layers of high-strength chemical materials. If you fall into the water, press the right button, and the left side will automatically inhale air, while the reflector will store it until it is full. The life jacket's maximum buoyancy is 10 kg/24 hours, but it should be kept as far away from the reef as possible to avoid damage.

3. Cross-arm life jacket for rock fishing: Rock fishing supplies, he has a pair of buttons on the front that must be pulled tightly when putting it on.
