it's non wetsuit.
all the skins are more or less equal. find one that fits your back curvature well and you're good.

Definitely a non-wetsuit swim. Water temp was 84 F (29 C) on race day and a lovely brown color. The water temp matched the air temp at 5:30 in the morning. Many people did wear speed suits, but others just raced in their tri suits. If you have a speed suit bring it - they are generally good for a 2 sec advantage per 100.
