How does drysuit diving differ from wetsuit diving?

Drysuit diving is fundamentally different from wetsuit diving in the way thermal protection is provided. A drysuit is designed to keep the diver completely dry by incorporating a waterproof shell. This is achieved through sealed seams and a neck seal, which prevents water from entering the suit while allowing the diver to wear insulating layers underneath. This feature allows drysuits to maintain body heat more effectively in cold water conditions. Since the diver remains dry in a drysuit, it also allows for greater comfort and extends the duration of dives in colder temperatures.

In contrast, wetsuits work on a different principle—they allow a thin layer of water to enter the suit, which then warms up from the body heat of the diver. While wetsuits provide insulation through the trapped water layer, this means that the diver is still exposed to the water, which can result in a decrease in temperature regulation over time, especially in very cold conditions.

Furthermore, while the cost of wetsuits and drysuits can vary widely depending on the brand and specific features, it is not accurate to state that wetsuits are generally more expensive than drysuits. The pricing can depend on many factors, such as material, design, and whether the suit is specialized.

The assertion that dry
