What Our Gearhead(R) Experts Are Saying:"I put the 4/3 Absolute Ultra Chest Zip Wetsuit through some genuinely cold, long sessions, and the Graphene Ultra lining held heat better than anything else I have surfed in at this thickness. The S-Zip opens wide enough that suiting up alone on a dark beach is actually painless, which sounds small but matters a lot when it is freezing out."Cold water lineups have a way of rewarding commitment, and the 4/3 Absolute Ultra Chest Zip Wetsuit from Billabong is built to make sure the suit is never the reason you paddle in early. Upcycler Pro stretch covers the body using 100% post-consumer recycled textiles, delivering a lining that is incredibly flexible and durable without adding the stiffness that heavier 4/3 suits are known for. Airlite 4D across the upper body keeps weight low and water absorption minimal, so the suit feels the same at the end of a two-hour session as it did paddling out. Graphene Ultra internal lining raises the thermal bar with an increased concentration of graphene-infused recycled nylon, engineered to deliver more warmth and flexibility than anything Billabong has built before it. OCENA natural rubber runs throughout the suit as the lightest, highest-performing natural rubber available, warming fast and moving naturally with the body. Welded seams combined with GBS construction keep everything locked down and water-tight from collar to ankle, and the S-Zip chest entry swings open wide for easy entry and seals with confidence once you are in.
