Open Water Tech Suits

The Category designations for swimsuits confuse me. When combined with wetsuit temperature requirements, my head starts to spin. Can someone tell me where the suits pictured here fit within the USMS system: 116531165411655 Other than the elimination of the zipper (on the full body) and the addition of the FINA logo, are these much different than the pre-neoprene tech suits from the mid-2000s (Fastskins)? I've competed in several races recently with these suits showing up on some fast swimmers, and I'm not sure how they are classified, but I know that they are not being classified as wetsuits. Can anyone clear this up for me?
