Matt Says:

"Billabong's Furnace Carbon X has been my go to wetsuit for the past few weeks and I have to say it is a VERY nice suit. One of the stretchiest suits I have worn, and Billabong seems to have stepped it up on the quality. If you are in the Northwest, or Northeast this is a great option that will keep you warm and as unrestricted as possible. I would definitely say this wetsuit is up there with the top hooded wetsuits we carry and worth spending a little extra on."


Cold water, gloomy skies and well groomed lines call for the comfort of the Billabong Furnace Carbon X 5/4 Hooded Wetsuit. This premium cold water wetsuit has insanely flexible AX1 Superflex Neoprene on top of plush and cozy Furnace Carbon Lining that not only insulates the core, but carries all the way down to the ankles. The exclusive technology behind this dry to the touch in seconds layer, utilizes knitted carbon yarns for maximum warmth and minimum weight. The Furnace Carbon X doesn't stop there by piling on fully sealed seams, both inside and out, wind resistant thermal torso panels and an improved DryMax II chest zip entry system. The Billabong Furnace is known for serious high quality and the Carbon X goes all out to deliver a longer, warmer in the water experience.
