Which characteristic is indicative of a properly fitted personal flotation device (PFD)?

A properly fitted personal flotation device (PFD) is designed to stay securely in place while providing buoyancy in the water. A snug fit ensures that the PFD does not ride up or come off when the wearer is in the water, which could compromise safety. The snugness should not be so tight as to restrict movement or breathing, but there should be minimal excess material. This characteristic is crucial because it allows the PFD to function effectively, helping to keep the wearer afloat and visible during emergencies.

In contrast, a loose and comfortable fit can be problematic in water because it may lead to the PFD slipping off, especially when splashing or moving. While it is important that wearers can adjust the PFD for comfort, a fit that is too loose can render it ineffective in keeping someone safe. Notably, PFDs are designed to be worn over clothing, but this does not mean that they should fit loosely. Additionally, while adjustability is a feature, it must be applied throughout the PFD for safety, not just at the straps.
