    O’Neill 3/2 PsychoFreak wetsuit
    I don’t normally take the time to write reviews but since this was a fairly expensive item that I would normally buy at a surf shop rather than online I thought I’d tell everyone that.......
    Dealing with Swim Outlet was fast, easy and they sent me exactly what I paid for on time at an UNBELIEVABLY GREAT PRICE! I had gone to a shop to get this suit but they didn’t have my size and said it would take 5-10 days to get. Thank God! It caused me to search online and I found it here and called and bought it for $100+ less. I thought it might be too good to be true after reading some negative reviews but kept my fingers crossed and SO came through with flying colors! Thanks so much. I will recommend you and continue to buy from you when I need something that you have

About This Brand


Jack O'Neill began surfing in 1952, before functional surf apparel was invented. While working for the Army Air Corps, O'Neill discovered neoprene foam in a DC-3 airplane. He then combined the neoprene carpeting with duct tape to create the first neoprene wetsuit.

Demand for O'Neill's neoprene wetsuits grew rapidly and he began a business selling the O'Neill wetsuits out of his garage. By 1980, he was a leader in the beach apparel industry with a thriving business. Since then, O'Neill™ has become a widely recognized and respected brand in the surf industry, continually creating new and innovative products. In addition to O'Neill wetsuits, they carry O'Neill boardshorts, O'Neill dresses, O'Neill hats, O'Neill rash guards, O'Neill swimsuits, O'Neill water shoes, O'Neill sandals, O'Neill life jackets and O'Neill t-shirts.

In addition to his business success, O'Neill also created a non-profit foundation for kids. O'Neill developed the O'Neill Sea Odyssey Program: a free, educational cruise that introduces kids to the microbiology of the Monterey Bay Marine Sanctuary, beginning at Jack O'Neill's doorstep.
