The Psycho One is one of O’Neill’s most flexible models and one of our favorite performance suits. Available as a 4/3mm in both chest zip and back zip versions, the Psycho One is the best value in the Psycho range of suits. This is one of our top picks and the back zip version, in particular, is one of the best back zip entries out there.
