Agreed. Neatly folded clothes in a gym bag that are immediately hung up when you get to the gym should not wrinkle. Unless OP is particular bothered by the smallest of imperfections, I don’t see how this is an issue.

But as others have said, a travel steamer could help get out those small imperfections.

And a Harris Teeter a little further. Adams Morgan is actually packed with grocery stores. There’s 4 total plus a couple liquor and convenience stores.
