I work just across the river from Campmor and live maybe 20 miles away.
I have friends who work there.
I have been ordering from there for over 20 years and only went there for the first time last year.
No need to actually go to an outfitter in my opinion, unless you really need to try stuff on.
Paragon at Union Square is probably the most complete outfitter in Manhattan, but that ain't saying much:-)
