What if this guy just grabbed gloves from his doctors or dentists' office? There are boxes of them everywhere in medical offices.
Or, at a restaurant, if he works in one? When I worked in a restaurant we had a storage basement with no cameras and would go down there all the time to get stuff. No one would notice if I took one box (or one pair, for that matter) of the many boxes of gloves.
The backpack is from one of the largest retailers in the US. He could have had it for 15 years.
I just am highly skeptical that the clothing/gloves/bag, which are all incredibly generic, will lead to an ID. Not to criticize those looking into those things! I'm glad people are and it would seem irresponsible for LE not to. I just think if I were to commit a crime I wouldn't go into my local Walmart to buy all the supplies a few weeks before... MOO
