What are yall using? Even if not in the great lakes, think 40-45F bottom temps. Just bought my first drysuit so need to get some undergarments..

Lake Michigan. Assume 40F.Which lake? Cause Lake Erie is a heck of a lot warmer than Lake Superior lol.
Weezle Extreme+ and external heat is the minimum for Lake Superior which is only warm at all fairly shallow.
No drysuit is going to be adequate for 90min dives in those temps. You'll need external heat for longer dives. But you also won't be on the bottom in 40F temps all that time either. So for the typical summer boat dive season you can do ok in a Halo, BZ400 or weezle extreme (no plus) without any heaters. But if you are shore diving in early March those are going to be inadequate since there's no thermocline, the profiles arent square and you're out there in actual 40F temps the entire dive - potentially shallow so you have all kinds of gas for that 45ft max or whatever tooLake Michigan. Assume 40F.
