You may also want to consider the standard most of us locals use which is the Omer 1.5mm Dahlak. In our warm water for many months of the year you only need the protection and not the additional warmth and buoyancy. The Dahlak has a lined interior which makes getting the suit on and off very simple and it doesn't retain as much heat as an open cell.
Open cell suits in less than 2mm are very fragile. A few years ago I begged Elios to make me a 1 or 1.5mm open cell/smooth skin freediving suit for here in south florida and was flat out declined. I ended up with a 2.5mm version.
Bottom line, strongly consider the Daklak.
