How should dry suit seals fit to function properly?

For dry suit seals to function properly, they must fit snugly yet comfortably against the skin. This snug fit is essential because it helps to create a watertight seal that prevents water from entering the suit, which is critical in maintaining insulation and buoyancy while diving in cold water. A proper seal ensures that the diver can remain warm and dry, minimizing the risk of hypothermia or discomfort during the dive.

If the seals fit too loosely, water can seep in, leading to a loss of thermal protection and potentially impacting the diver's safety. Similarly, if the seals are overly tight, they may restrict movement and cause discomfort, which can also be detrimental to the dive experience. Therefore, finding the right balance where the seals are snug but not uncomfortably tight is imperative for both comfort and safety during dives.
