I have one and generally like it, but here is my 2cents.
1) It is NOT a semi-dry suit. It has nice seals at the wrist and ankles which reduce water flow for added warmth which is nice, but does not seal as tight as a good semi-dry. It is not as expensive either. It is a tweener, but I guess this can be said to some extent of most semi-drys also.
2) Properly sized, it is very easy to get in and out of. This is due to the stretchy material. There are 2 downsides to the material, it is not as tough to abuse (can blemish the outer skin) and it compresses at depth. I.E. It is a very warm suit in modest depths, you approach 100' and it gets cool fast relative to stiffer neoprene.
3) The integrated hood is a big plus, no asking your buddy to tuck in the hood. Simple to don/doff or 1/2 peel down for a SI. Great for solo dives.
My conclusion was the SolAfx was nearly as buoyant as a FJ_J and slightly cooler at depth. Despite this, it is faster to don/doff and more comfortable for all-day wearing on a boat. I love it for So Cal diving, Nor Cal is might not be enough suit long term.
