There are a lot of options for cold weather gear. Wet suits, dry suits, dry tops, dry pants, etc. I’m guessing one would opt for a wet suit because of the relatively low price, and a dry suit for the comfort. But could someone explain why they’d choose separate dry top/pants combinations over a one-piece? Since they exist there must be a market for them. I’ve also come across a new product that seems to be a skin tight dry suit (www.seasonfive.com). Could anyone explain all this? Have I missed any other options?
