I have a Santi E-lite Trilaminate drysuit. I wear this suit for all my diving whether it's 80 deg or 32 deg water. Trilaminate suit’s have no insulating properties so just bring the correct undergarments. I use the fourth element undergarment system. Drybase for warm water. Zerotherm or/and Artic for colder water.
I was in Greece this past summer and wore the drysuit with the Drybase and loved it. This combination of Drybase and undergarment is comparable the flexibility of a 3mm wetsuit. Most of the other divers were wearing 5mm's. Everyone thought I would be too hot. Not a problem. I don't like getting dressed on moving boats so I get dressed just before we leave dock. I kept it unzipped and top down just as I would be during service intervals. When you reach the dive site your ready to go in less than a minute. You will really appreciate your drysuit on multiple dives or trying to get into that not dry yet wetsuit. As always, wetsuit or drysuit, stay hydrated. Think about getting a p-valve installed. Hopefully you have the thigh pockets installed.
I know you said you were driving but as for the airplane, I pack my drysuit, undergarments, regs, computer, can light, drynotes, spool, two backup lights, dive alert and reel with my carry-on. I used my drysuit bag which is a little large, but compressible.
Backplate, detached STA, wing, SMB, lift bag, masks, fins, knife was with checked baggage. All that was needed was tanks when I get to my destination. I dive the same equipment for all my dives, except for the reel and can light which depends on the planned dive. But I will have them with me if needed. This sounds like a lot, but my checked bag weighs in at 50 and the carry-on doesn’t usually get weighed.
Enjoy your new suit! The odds of you diving more throughout the year has greatly increased.
