1. What is buoyancy?

Buoyancy is the upward force exerted on an object submerged in water. A relaxed person without excessive water intake can naturally float, providing about 95% of the needed buoyancy. Therefore, the life vest only needs to provide enough buoyancy to keep the head above water.

2. How much buoyancy is needed to keep the head above water?

An average adult requires approximately 3.5 kg of buoyancy to keep the head above water. This life vest provides more than 7.5 kg of buoyancy, ensuring safety.
