It’s Florida, so i would say the most important part is before and after the dive. I get ready pretty fast and usually end up waiting on others to get ready, which was miserable. I dove lava core top with hood and bottoms, with technical shorts over for three to four dives a day when i did my cave course. Only started to cool off on the last dive which was over two hours. My instructor wore a dry suit and he sweat so much it was just as wet inside the suit.
