Is wearing a flag patch on a backpack against regulations?

I say show the colors. I have a cap and wallet with old glory. I bought a red, white and blue watchband. to wear on the one-handed watch that came from russia. guess that makes me a subversive.

Don't see why it should be. Civ backpack?? If sewn properly and right-side up, who would say anything? Military ruck?? Probably not the best idea, but again if displayed properly and within unit standards (does whole unit wear similar?) , dont see a rub.

True Confession years later: Some may not find it amusing but for a long while I wore Fry Jet Boots with my USAF Class B uniform. Pull on boots were not authorized, but I had a shoemaker install six eyelets on the boots and put black laces on them, making them technically compliant. Black smooth toe, a set of six laces and a good shine. I never pushed it by trying it in a formation, or while speaking at Commanders Calls (gave security and safety briefings). It probably made me a worse NCO but I was never confronted over it. Actually it was far more military than scuffed up "combat boots" or unpolished low quarters. But not so uniform.

Another suggestion to get rid of our flag.

Reading this on a blessed Sunday morning, I am not going to jack up a kid in this day in age over them wanting to project patriotism. I believe the correct answer after reading some of these awesome arguments is since we are service members it is up to us to lead by example. If you are corrected and shaky on your reg's then go find the answer and live by being the example. Those who show the desire to follow will follow your example because anyone putting out the effort these days to be patriotic wants to be lead to the right answer, activity, form and fashion. I have never met anyone who takes it upon themselves to do anything that is not receptive to considerate correction. Having been a member of a few NG units, never with a flag issue, but we did a few uniform practices that I felt/know were not correct. After reading one of the CSM's responses, your not in uniform unless you are doing what everyone else is doing in formation. All The Way

Our unit went through this discussion in 2012 and back then it was the Commander's discretion as that is an "accessory".

Read the Regulation
What does it say?
Arm yourself with knowledge so when you are asked you can state with confidence what is right and what is wrong

I say no

I carry a backpack to work every day and it has a flag on it

depends on the flag, the backpack is an extension of your uniform, its often addressed in local policy, SOP, blue book etc, if it doesnt go on your uniform, you certainly shouldnt add your 32 pieces of flare on your backpack, save it for your civilian clothes, and your best answer will come from your local supervisors
