Dry suit diving in Iceland

When you visit Iceland and dive at places like Silfra, it doesn't take long to understand about the importance and value of a dry suit; its probably the most important aspect of the entire experience, (apart from having enough air)! Many people ask me; "What is the difference between a wet suit and a dry suit"? Answer: Dry suits are different from wet suits in the way they insulate your body; simply put, one is dry, the other always wet then eventually very very cold - the end result can be brutal and potentially dangerous. What's nice about wearing a dry suit is being sealed at the neck and wrists, meaning everything with help of physics should, and will remain dry...Well that's the plan anyway!
