Another thread about thermoprotection, sorry for that
My wife and I have booked a trip to Socorro for March 2024, and I'm very excited. However, we've never dived in cold water before (I heard that Socorro in March can be as cold as 20 degrees Celsius). In June, we were in Egypt doing BDE, and we had 25 degrees Celsius, which was the coldest water we've experienced. We both own 5mm Scubapro Everflex wetsuits, but nothing thicker so far. We've never tried drysuit diving, so that's not really an option for us.
I checked with the operator, and they offer 5mm or 7mm wetsuits for rent (they don't seem to have semi-dry suits). My local dealer also rents 7mm wetsuits, but they don't have semi-drysuits available. While we are not particularly sensitive to the cold (we've never felt cold before, but I attribute that to always having the right protection), I would hate to skip a dive in Socorro just because I'm cold.
I've read this forum and found people diving in shorties, while others say they would have frozen without a drysuit, so it's difficult to form a definite opinion. I'm seeking your recommendation:
1. Should we buy a 7/8 mm semi-dry suit (as it seems difficult to rent one)?
2. Should we rent a 7mm wetsuit?
3. Is it possible to use our Scubapro Everflex 5mm wetsuits and buy underlayers (if they exist)? I heard something about sharkskin, but I'm concerned it might make the wetsuit too tight.
Additionally, I have 5mm boots. Would they be enough? What are your recommendations for the hood and gloves?
Thank you so much for your precious advice. I really want to make the best of this trip without worrying about being cold.
