I have just signed up to take a drysuit class in a week and a half. My certification dives are going to be in 53 degree water and I am concerned about what I should wear for undergarments. The instructor told me that something like the middle layer of ski clothes work well but I have nothing like it. He also showed me some nice thinsulate underware but I can't afford it. I am hoping you guys have some ideas for something that I might have at home or that is less the $30
Any help is appreciated
