4/3mm Men's O'Neill HEAT Fullsuit
The O'Neill HEAT is a sweet, high-end wetsuit, with lots of nice refining features. The entire suit is made of 100% superstretch neoprene for maximum flexibility in the water, and fewer seams for even more stretch. The waterproof back zipper works in conjunction with the external liquid taped seams, and the anti-flush neck seal to keep cold water from penetrating the suit. A poly fleece chest & back lining wicks moisture from the skin, which really helps with thermal insulation. Also features an external key pocket, and durable kneepads. The Heat has been O'Neill's best selling suit for a long time, you should check it out!
