Some things just can't be made better. The 1st wet suits were smooth rubber inside and outside we used talc powder to ease the entry. Those were mainly 1/4" to 3/16" thick. Somebody started putting linings on the inside while other added zippers at the wrists and ankles as well as the lining to ease entry. The smooth skins suits were then considered obsolete, by the dive manufacturers anyway. Apparently some of them have re-discovers the warmth of these suits.
I totally agree. My first wetsuits were smooth skin inside and when manufacturers went to lined insides they seemed not as warm as the old smooth skin suits IMHO. Today all I will ever use is a custom smooth skin inside suit. As said above it's good some companies are now offering this rubber option again.
