What could lead to insulation loss in a dry suit?

Insulation loss in a dry suit can occur due to air leaks. When the suit is designed to keep water out and air inside, any breach in the suit’s integrity—such as a tiny hole or a failed seal—can compromise its ability to maintain warmth. This is because the trapped air provides insulation and minimizes heat loss from the body. If air can escape through leaks, the insulating layer diminishes, leading to potential cold exposure for the diver.

While water entry, inadequate weight distribution, and excessive buoyancy are related to the overall function and comfort of the suit, they do not directly impede the suit's ability to insulate in the same way. Water entry would affect thermal protection but is not categorized as insulation loss in terms of air leakage, while adequate weight distribution and buoyancy issues pertain to the diver's control and movement rather than insulation integrity.
