I'd expected to find such a thread...perhaps these questions should be merged elsewhere...

I am Pre and CLEAR, FWIW...

Curious as to why I can wear my rather heavy "job" shirt through security, but can't wear a lightweight fleece jacket, even unzipped, I have to put it through the scanner. For those of you who don't know what a job shirt is - it is a heavy outer layer - usually two layers itself with a v-neck zipper. It is certainly much heavier than most spring/fall jackets.

Curious as to why I have to sometimes remove my nylon-like web belt with plastic buckles. I switched to such a belt when traveling as my supposed TSA-compliant "dressier" belt still set off the metal detector 1/2 the time. Some TSA agents want me to remove the nylon-like belt, some don't (and I pass through without an issue). I surmise that the TSA agent is simply not knowledgeable about the material and would rather me pass through without any glitches. I'm not going to argue about a simple matter and removing it is not a big deal. As I stated, just curious...
