What Our Gearhead(R) Experts Are Saying:"I wore the 5/4 Salty Dayz Hooded Chest Zip Wetsuit through a full week of cold, overhead surf, and the Graphene Ultra lining kept me so consistently warm that I stopped thinking about water temperature entirely. The fit is exceptional for a hooded suit, nothing bunching or pulling at the shoulders, and the style actually made me look forward to suiting up."Cold water does not have to mean sacrificing style or movement, and the 5/4 Salty Dayz Hooded Chest Zip Wetsuit from Billabong proves it session after session. Built on the elevated Surf Capsule platform, this suit brings together Billabong's most advanced technologies inside a design that looks as good on the beach as it performs in the water. Upcycler Pro stretch covers both the body and upper body using 100% post-consumer recycled textiles, creating a lining that flexes in every direction and holds its shape through a full season of demanding use. Graphene Ultra internal lining sets the thermal benchmark, engineered with an elevated concentration of graphene-infused nylon to deliver maximum warmth and flexibility where a 5/4 suit needs it most. OCENA natural rubber throughout provides the lightest, most responsive foundation available, moving naturally and warming quickly even in the coldest lineups. Welded seams combined with GBS construction seal every seam from collar to ankle, and the chest zip entry keeps flush minimal so the only thing you feel out there is the pull of the next wave.
