“I have always had great luck with ordering Oneill wetsuits online, previously Psycho 1's. The Psycho 1 was not available this year, so I ordered the Hyperfreak instead. It seems like a 5/4, it is so thick and it is very tight in the shoulders and arms. I thought it would stretch out in the water, but it did not. It is constrictive while paddling and leaves stitch marks on the arms and legs because it is so tight. I would definitely recommend trying it on in the store before buying it even if you bought one last year in the same size.”
