What is a consequence of wearing non-swim attire according to the Swim Attire Rule?

Wearing non-swim attire can present a drowning hazard primarily because such clothing is often made from heavy materials or fabrics that absorb water. When these materials become saturated, they can weigh a person down significantly, making it difficult to swim or stay afloat. Additionally, loose clothing can easily entangle in equipment or limbs, further increasing the risk of drowning. This hazard is particularly pronounced for inexperienced or non-swimmers who may struggle even with minimal assistance if weighed down by inappropriate attire. For safety, swimwear is specifically designed to be lightweight and minimize drag in the water, ensuring that swimmers can move freely and safely.

Other attire choices, such as typical clothing or denim, do not provide these advantages and can instead create substantial risks in the aquatic environment.
