What do people wear under board shorts?

Question

I know this is such a weird question, but I need to know. Does anyone in California or another surfing state know what you are supposed to wear underneath board shorts?

Answer 1

Been surfing all my life and found that spandax biker shorts work best. They are similar to a really thin wetsuit, tight to the skin and help preven rashes that you board shorts give you from rubbing against your skin. Also, they help keep you a little warmer.

Answer 2

No.  Don't wear anything.

Answer 3

Free and easy works for me.

Answer 4

in hawaii most guys wear boxers or nothing under, and girls wear a swimming suit bottom.

Answer 5
