  • Extra 0.5mm thickness
  • Technobutter 3X Neoprene: O'Neill's lightest and stretchiest ever. The TB3X is actually pre stretched to break the fibers to a point that they're flexed to the max, yet still hold their form. It's low profile also increases warmth by shedding water away from your skin.
  • Technobutter 3 Neoprene: Highly stretchy, durable, soft and hydrophobic. The finest technical yarns are highly water resistant yet tough enough to withstand the heaviest surf sessions. Velcro resistant and soft feel to touch is just the icing on the cake.
  • TB3X Tape Seam: The lightest the stretchiest neoprene seam tape you can get! 0.5mm split neoprene added to the triple glued seams to keep you dry with minimal restriction.

  • Upper Body/Legs: Technobutter 3
  • Arms/Shoulders: Technobutter 3X
