What should be the primary consideration for exposure protection?

The primary consideration for exposure protection when diving is fit. Proper fit is crucial for ensuring that the dry suit functions effectively as a barrier against water, maintaining thermal insulation, and allowing for mobility while diving. A well-fitted dry suit prevents water from leaking in, which helps to keep the diver warm and comfortable throughout their dive.

Additionally, a suit that fits correctly enhances the diver’s ability to move freely, which can be vital in scenarios requiring physical activity, such as handling equipment or maneuvering underwater. It also minimizes the risk of discomfort or injury caused by excessive tightness or looseness.

While factors like cost, color, and style may influence a diver's choice, they do not take precedence over fit. The most critical aspect of staying safe and comfortable during dives in cold water is ensuring that the exposure protection gear is tailored to the diver’s body, as this directly impacts performance and overall experience in the water.
