All right, if people see me as "that guy," then I'm just gonna run with it:
"Patches may be affixed to the CWU-36/P Summer weight jacket either by hook and pile (Velcro) or directly to the jacket at the discretion of the individual, subject to commanding officer guidance. Patches shall not be affixed to the Multi-Climate Shell jacket."
This line is probably where the confusion is coming from. I have no idea what the "Multi-climate Shell Jacket" is, but the other one is the Nomex. Also, this one doesn't have a limit on how many patches like the reg for the leather jacket does.
This sounds like the Gore Tex shell that is used with the fleece kit. Even the sweet fleece vests that the helo bubbas love to wear.
