I just purchased the 2012 Oneill Hammer spring suit. It is excellent. It feels like they have made alot of important changes in the comfort zones. Arms feel more looser and freer when paddling and the back zip is easy to get into and has a locking zipper plus double neck seal. The water was a brisk 67 degrees and the Hammer kept me nice and warm. Excellent suit at an excellent price. The seams are solid and I dont have to worry about pulling apart the wrist cuffs when getting it on or off. Excellent.
