Billabong Intruder 5/4 mm

If you're after a cosy-warm covering of 5mm neoprene to keep you comfy in the cold water then the Intruder 5/4 Back Zip Wetsuit from Billabong might be the one. It's got a healthy thickness of rubber so it'll keep you out at the break, and not breaking the bank.
As stretchy as it gets in a back-zip steamer.

The Billabong Intruder 5/4 GBS Back Zip Wetsuit combines lightweight and stretchy neoprene that offers you all the movement you need to surf, whilst keeping you warm at the same time. The back zip is a traditional but tested entry system that works exceptionally well here with a snug Velcro anti-flush collar. Glued and blind-stitched seams ensure it's watertight and adds life to this Billabong steamer.
