Now available for the ladies, the O'Neill Women's Psycho Freak 4/3 Wetsuit is here! By combining the high tech features of the Psycho Freak line with the performance features of the Psycho III, O'Neill has created the women's Psycho Freak and it's awesome! This is the suit to get if you're looking for ultimate warmth, fantastic flexibility and lightweight comfort plus all the bells and whistles you need for an insane wetsuit experience.

Starting with super stretchy TB2 Neoprene, the Psycho Freak is soft and pliable, lightweight and has improved durability. TB2 Air Firewall Neoprene is added in the chest and back for its lightweight thermal insulation properties. Then all seams are sealed with O'Neill's exclusive Double SuperSeam Weld watertight stitchless technology keeping cold water out and warmth and body heat in. The ankles and wrists have a low profile with Super Seal Cuffs and are kept securely in place with Plasma Seals.

The Psycho Freak continues to deliver with its patented Z.E.N. Zip Closure System with a drainhole, keeping you warmer by blocking flushes and draining excess water out. Seamless paddle zones allow you to move without restriction and the Double Super Seal Neck is soft and chaff free for a comfortable fit. If you're seeking a highly innovative suit that won't disappoint, check out the insane Psycho Freak.

O'Neill Women's Psycho Freak 4/3 Wetsuit Awesome SuitReview by Mary Mary
I like everything about my O'Neill women's Psycho Freak 4/3 Wetsuit: very easy to put on and take off, the small back Z.E.N.Zip closure system is the best system I have used, the sealed neck is warm and doesn't scratch or leak, TechnoButter Neoprene is the best. This Wetsuit is warm and comfortable to wear. I highly recommend it.
