The Billabong 4/3 Absolute-X Back Zip Wetsuit has all the same performance-oriented features as the Absolute Comp, but with added Liquid External Welded Seams for extra water tight and durable seam sealing. A back zip entry system means less time spent struggling in the parking lot while the Hollow Fiber Thermal lining in the chest and back mean more time in the water. Don't settle for a warm suit that doesn't paddle nicely (or vice versa), opt for the Billabong 4/3 Absolute-X Back Zip Wetsuit and get the best of both worlds without compromise.
