When selecting a PFD, what is the most important factor to consider?

The most important factor to consider when selecting a Personal Flotation Device (PFD) is its size. A properly sized PFD is essential for effective safety and buoyancy. If the PFD is too small or too large, it may not provide adequate support in the water, increasing the risk of drowning. A correctly fitting PFD will ensure that it remains securely in place, allowing for maximum buoyancy and comfort, which is critical in emergencies.

While the style, cost, and material of a PFD are certainly factors to consider, they should not take precedence over size. The style may affect comfort and appearance, the cost can influence purchasing decisions, and the material can affect durability and weight. However, none of these aspects can substitute for the fundamental need for a properly fitting device that will keep a person safe when they are on or in the water.
