I imagine the artifical skin (something they talk about rather indepth in game for not being conviencing) that he was shown in at the end of MGS4 is the 'wearable' part. When he's on mission where there's a chance he'll need to fight, it makes sense that he wouldn't wear his artifical skin and just go in the basic cyborg frame he was already in. There was obviously some modifications to his frame, but it's a body containing the still-nessacary organs and other cybernetic systems, artificial or no, to keep the brain functioning. It's not something you can take off. Heck, it doesn't even look like really any different from how he appeared in 2014, just updated to look better. And since he's working with cilents personally now, it makes sense he wouldn't have the entire visior on and would also keep the artifical skin on the lower jaw.

Ask the Konami guy at E3, because he made it clear he wore his MGS4 body as an equippable suit, and also noted that his human-looking body was a cyborg body.
