    Cold water means hot waves.

    Killer breaks aren't limited to tropical beaches, which is good news if you live in the Pacific Northwest, New England, or Duluth. The good news is tempered a little bit by the fact that the water's icy, so you can just throw on some board shorts, toss your board in the back of your truck, and cruise down to the beach for a low-key day. When cold water means things are a little more serious, zip up O'Neill's Psychotech 5.5/4 Men's Hooded Wetsuit.

    Seeing as it's O'Neill's top-shelf cold-water suit, the PsychoTech employs two of the company's finest types of neoprene, TechnoButter 2 and TechnoButter 2 Air Firewall. The latter, a super warm and flexible material, makes up the majority of the torso to keep you comfortable in cold water, while the former is lighter and stretchier to provide unlimited mobility in the arms, legs, and shoulders. O'Neill arranged the panels with seamless paddle zones and a Lumbar Seamless Design to increase flexibility and decrease irritation, and joined them using waterproof, durable, and highly flexible Single Fluid Seam welding, which foregoes stitching for a smoother, warmer construction.

    Staying warm in icy water is all about preventing flushing, so the PsychoTech made stopping leakage a serious priority. To that end, the Double Super Seal neck has an attached cinch-down hood, and the SuperSeal cuffs are finished with Plasma seals to form the snuggest seal you've ever seen. The F.U.Z.E. floating chest zip is easy to get in and out of, but its most important feature is the waterproof back panel, which blocks any water that sneaks through the zip and steers it out one of the strategic drain holes before it can drip into the suit and sap your precious heat.

    • Familiarity: I've put it through the wringer

    The fit and finish on this suit is awesome. The seam (there's only one continuous one) is welded very well, and the extra material in the knees and chest is integrated comfortably. Overall, you barely know you are wearing a suit!
