The 4/3 mm Billabong Furnace Comp is the men's version of Billabong's premium neoprene in 4/3 mm thickness, designed for full winter and shoulder season in Mediterranean waters.

Technology. Furnace Carbon thermal lining with carbon threads on torso and back that maximize heat retention while minimizing weight, paired with Graphene Recycler lining in core zones. AX1 Airlite super-stretch neoprene partially recycled, GBS (Glued and Blind Stitched) seams with full tape-to-tape internal sealing head to toe, Fluid quick dry pattern that channels and evacuates water, and chest zip entry with Hydrolock closure.

In the water. It's the reference model for riders who enter the water all through Mallorca's winter (14-18°C). 4/3 is the year's best seller: warm without feeling heavy, keeps shoulder flex for paddling, and thermal panels on the torso don't mat down after hours of session.

Furnace Comp 4/3 or Absolute 4/3 — how we see it at El Niño Mallorca. Furnace Comp is the premium option: lasts longer and feels it from day one. Absolute is the solid mid-tier choice. If you're in the water a lot, the Furnace upcharge pays for itself fast. If unsure about sizing, visit the shop in Pollença or message us.
