Billabong Synergy 4/3 GBS Back Zip Steamer Wild Black Wetsuit

The Furnace Synergy Series delivers lightweight, premium heat and innovative technology with superior value. Lined with ultra warm Furnace quick dry, the double knit jersey creates air pockets that trap heat and allow for optimal drainage. A Superlight Foam core provides 250% stretch with excellent thermal retention, and a Superflex 250 Jersey tops it off for added insulation and low water absorption. Created with clean, contoured seams and optional colour blocked panels, the Furnace Synergy delivers everything you demand from a premium wetsuit, without breaking the bank.
