The zip is double ended so males can still use the convenience zip on the dry suit. My one minor criticism on this suit is that as supplied, the alloy crimps at the top of the zip were razor sharp and cut my neck first time out. Two minutes with a nail file rounded the sharp edges. The Arctic one piece is not cheap at £189 but I think it is worth every penny.
My overall verdict is that the fourth element Arctic one piece is essential wear both for comfort and safety when sea kayaking in the Scottish winter.
