The question was what class wristbands fall under. How the wristbands are marketed has no bearing on what class they fall under.
Wristbands may fall under multiple classes, depending on their exact nature/design/etc. Mikepro1 cannot control the classes they fall under. He can hypothetically control which of the classes he were to denote on a trademark application. The class or classes he would want to include IMO would hopefully depend at least partially on how the wristbands were marketed.
I might not have originally been extremely clear in my initial response, and may have inadvertently been a slight bit misleading - but thats already been pointed out. With all do respect I stand by my reply.
For Mikepro1's further reference, if he wanted to figure out exactly which classes that a silicone wristband could possibly fall under, the following two links would likely help him out:

Either you know what you're talking about, in which case you should post it, or else you should refrain from doing so.
My intent was and is all good. Seeking to provide helpful input is separate than seeking to provide formal legal advice. With all do respect, I do believe that my input was relevant to the information the OP was seeking, I do not believe that it would have led him to take any unhealthy action, and it was two days since the original post before anyone else replied.
If you can improve on what I said, great.
I could have given a more detailed reply, but I wouldn't have necessarily felt comfortable seeking to do that when others on the board including yourself have more experience and education pertinent to the subject matter.
I will also point out that according to the USPTO's guidelines for international classification as stated in chapter 1400,
"Finished products are classified, in principle, according to their function or purpose or the industry that produces them or, secondarily, according to the material of which they are made or the trade in which they are sold."
A product's function is affected at least slightly by how it is marketed. The trade in which a product is sold is determined by how a product is marketed, as it is determined by a product's marketing channel(s)
FWIW, your analysis of the t-shirt hypothetical is largely wrong.
While standing by my hypothetical analysis as far as practical purposes are concerned, I will certainly give you the benefit of the doubt here. Considering that a correct analysis may be helpful to the OP as well as lurkers that may be curious, perhaps you could explain why it is largely wrong.
