The buoyancy of the high-buoyancy marine 275 life jacket is as high as 275N, which can easily bear the weight of an adult of 150kg, and ensures that even in a coma, the life jacket can still float face up on the water to prevent drowning. It has high visibility and is equipped with a lifejacket light and reflective strips, allowing search and rescue personnel to quickly find people who have fallen into the water at sea. When sailing at sea, only by wearing high-quality adult life jackets can the crew ensure their survival in the face of any emergency.
