The Prolimit Fusion 3/2  back zip steamer is a great mid-priced performance wetsuit. The vertical back zip has its own seal, which ProLimit say adequately blocks water entry for a 3/2mm wetsuit. Please note that there are no zip flaps or water barrier behind the zip, the zip is the seal. Full GBS (triple glued and blind-stitched) seams and it incorporates the flexible and hard wearing Airflex 500+ and 300+ Limestone neoprene.
