Infant life vests are recommended for anyone who weighs less than how much?

Infant life vests are specifically designed for the protection of young children who may be at risk in emergency situations, particularly during water landings. The recommendation that these vests be used for infants or children who weigh less than 35 pounds is based on safety regulations and standards aimed at ensuring the proper fit and buoyancy for smaller individuals.

A life vest that is appropriately sized for infants provides better support and increases the chances of survival in the event of an accident. They are constructed to keep the child’s head above water and are designed to fit snugly to prevent slipping off, which is crucial for effective buoyancy.

Choosing a weight limit such as 35 pounds ensures that the vest provides the necessary flotation while allowing for proper movement and comfort. It's important to adhere to these guidelines because using a vest that is not suitable for the weight of the child can lead to safety risks, including inadequate flotation support in an emergency. The other options reflect weight limits that exceed the recommendation, which would not provide the safety measures essential for children in that critical weight range.
