What is the primary purpose of ensuring seals are secured when donning a dry suit?

The primary purpose of ensuring seals are secured when donning a dry suit is to prevent water leaks and retain warmth. Dry suits are designed to keep divers dry by using seals at the neck, wrists, and ankles, which create a barrier against water. When these seals are properly secured, they help maintain a stable microclimate within the suit, preventing cold water from entering and ensuring that the diver stays warm even in chilly aquatic environments. This is especially crucial in maintaining body temperature during extended dives, particularly in cold waters where the risk of hypothermia is higher.

While buoyancy, underwater visibility, and movement may be considerations in diving, the primary function of the seals directly relates to thermal protection and keeping water out of the suit. This ensures divers can focus on their activity without the discomfort and dangers posed by water intrusion.
