    A quality, 4/3mm wetsuit that doesn't put a serious dent in your wallet.

    During your last surf session you barely lasted an hour in chilly waters, so equip yourself with the O'Neill Men's Epic 4/3 Wetsuit before you head out again. Ideal for cold to cool surfing conditions, the Epic has FluidFlex Firewall insulation in the chest and back panels to lend extra heat and to wick away moisture for improved comfort. 4/3-millimeter UltraFlex neoprene fabric throughout offers plenty of stretch, flexibility, and unrestricted movement while you surf. Strategic seamless paddle zones (undersleeve panels) also allow for unrestricted motion and help to eliminate chafing.

    O'Neill utilizes a Lumbar seamless design (LSD), a large panel in the rear area of the wetsuit to minimize water entry and maximize stretch and overall comfort when you spend significant amounts of time sitting up on your board to spot oncoming sets. Thanks to the Epic's glued and blindstitched seams, this stellar suit stops water leakage for all-day comfort. A back zipper with glued-in covert zip, double super-seal neck, and updated hook-and-loop closure prevent uncomfortably flushing issues and provide minimal bulk and a chafe-free unfinished edge. Krypto knee pads with ergonomic shaping offer durability and help protect your knees when you duck dive while an external key pocket with loop houses your car or beach house key.

    Sweet Wet Suit

    • Height: 6'2"
    • Weight: 250lbs

    this is the first wet suit i have owned, and so far so good. i bought this to go through some late season canyons in Colorado. ive done several canyons in this and so far ive been pretty happy. Cayoneering usually beats up wet suits pretty quickly, but this has held up to the challenge. it also comes at a great price. if you are looking for considerable warmth and a great fit that wont break you bank, this could be the wet suit for you!

    Great Wetsuit

    I used this a few weeks ago surfing on the coast of Santa Cruz and I loved it! I stayed completely warm in the water for hours without issue. The wetsuit was comfortable, easy to put on, and a good fit. The pocket on the leg was also very useful. My only complaint is that the neck was a bit tighter than the rest of the wetsuit.

    Overall, I would recommend this to anyone looking for a light wetsuit.

    Oneill has been my wetsuit of choice for the last decade and fits my body style like a glove. Big shoulders, lats, and chest. I run hot and this keeps me that way.

    Solid Wetsuit

    I bought this as a gift for my friend Mason, and here is his impressions:

    So far I have been very pleased with my O'Neil wetsuit. I have been surfing in Northern California and have been surprised how warm I have stayed. Also pleased with the comfort. I've never felt uncomfortable in it. I would recommend this suit to anyone.
