A sizing guide provided by Connelly, a manufacturer of personal flotation devices (PFDs), helps individuals select the appropriate fit for their life vest. These charts typically correlate body weight, chest measurements, and sometimes height with specific vest sizes, such as small, medium, large, and extra-large. For example, a chart might indicate that an individual with a chest measurement of 40-44 inches should select a large-sized Connelly life vest.
Properly fitted PFDs are crucial for safety during water activities. An inappropriately sized vest may not adequately keep the wearer afloat or could slip off in the water, negating its intended function. Historically, reliance on generic sizing often led to ill-fitting vests and increased risk. The introduction of manufacturer-specific guides aims to improve the accuracy of fit, leading to enhanced safety and comfort for users.
