The O'Neill HyperFreak Comp 4/3 Zipless Wetsuit takes a simple yet serious approach to a highly flexible, competition ready cold water suit. Sporting super stretch Technobutter 3 Neoprene in the legs and torso and light and soft Technobutter 3X Neoprene in the paddling zone, the Hyperfreak delivers insane comfort and reliable warmth. The durable glued and blind-stitched seams are internally sealed with TB3X split neoprene tape to minimize water leaks and add longer life to the suit. Topped off with a water tight zipless entry system for a quick, fumble free in and out, and the HyperFreak Comp is one pro level wetsuit that is hard to beat.

O'Neill HyperFreak Comp 4/3 Zipless Wetsuit love this suitReview by BlueJava BlueJava
Super comfy, easy to get on/off, plenty warm (water temp currently high 50's here in Central Cali). This is a wonderful wetsuit. I'm right in the middle of the size specifications for an MT. It was super tight the first couple of times I put it on, but loosened up a little and is now perfect. I definitely like the minimalist design. Great flexibility!

O'Neill HyperFreak Comp 4/3 Zipless Wetsuit Tremendous suit!Review by SharkBoy SharkBoy
Surfing in New England a 4 3 is essential as the water turns.
This zipperless did not flush at all and was easy in and easy out.
Water was 48 and I was toasty warm. Very flexible as well, felt more like a 3 2.
Technobutter 3 is the real deal and if you are looking for a 4 3 zipperless this is the one!
