The Billabong Salty Dayz Natural 4/3mm Chest Zip is Billabong's top women's surf neoprene range in Natural Upcycler version (eco-designed line), 4/3 mm thickness designed for winter and shoulder seasons.

Technology. Graphene Recycler Plus thermal lining in torso and back panels, combined with Silicon Stretch interior on legs and sleeves for easy on/off. Superlight Foam partially recycled from upcycled tires, GBS seams (Glued and Blind Stitched) sealed with Super-Flex Neo Tape and solvent-free water-based adhesives. Chest zip entry.

In the water. The Salty Dayz Natural 4/3 covers Mallorca's winter temperatures (14-18°C) without losing elasticity. The Graphene lining activates heat quickly after the first water rinse and the women's cut respects the silhouette without pooling water at the lower back.

Salty Dayz Natural or Furnace Comp — how we see it at El Niño Mallorca. Salty Dayz is Billabong's premium women's line with an eco focus. If you want maximum thermal performance, Furnace Comp Women is the other option. If unsure about sizing, reach out before ordering and we'll nail it.
