I would think anything with a chamois would raise the same issues as sanitary pads and incontinence products. Which I would think have to come off, since they just present as pads on the scanners, and they can't tell what's in them by touch. I wonder about breast cysts on a grope-down, too.

Someone outfitted in cycling gear probably looks so bizarre in an airport that they wouldn't fit any profile but isn't the plan to eventually put everyone through the X-rays?
