For cold water divers, a drysuit is the best way to stave off the effects of exposure, especially if you’re on longer bottom times or if like us in BC, the best diving season corresponds with the colder parts of the year. A good drysuit is an investment though, and not something you should jump into casually. The type of diving you do, and the amount you’re able to invest, are the best ways to initially determine which type of drysuit may be best for you.
