During my certification dives for open water I used a rented 3mm John and Jacket in the springs (temp is 72 F). We had down times of only thirty minutes, but by the time I was done my whole body was shaking and my lips turned blue.
Would the 7mm neosport John and Jacket be a good buy so I don't freeze or is there possibly a better deal for the protection I can get? I'm just not sure how much wet suit would be enough for me. Thanks for help.
