I’m diving the Buccaneer (70ft) and the Straits of Mackinac (80ft) this weekend, which are located in the southern part of Lake Michigan. I’m pretty comfortable in my 7mm Hollis Neotek semi-dry suit in colder waters (50° or so). I know much of this boils down to personal preference, so I’m really just looking for a sanity check. For anyone who has been to these spots or anything in the region in summer, is a drysuit a must? Thank you!
