I bought the most amazing black canvas bag in NYC last year - great cotton, so simple, so sturdy, perfect feel, perfect size, no label or brand whatsoever, it was instantly a great classic that I would take everywhere - and it cost something like 30$ !
Since there were no labels, I didn't know where it originated from, and had to send a spy in the shop to scout the info for me during his recent NYC trip- and he successfully found the precious info : Rothco military bags!
The website is not very welcoming, its basically a military surplus provider, but damn, the bags are very nice, including the Air Force crew bag and the duffle bags, mine is the "parachute cargo bag"...
The old man who sells roasted chestnuts on the place St Germain des Près seems to have been there forever. These guys are all over the city, but his craft is the pickiest: he sells them in a double white paper pouch (and not some dirty newspaper cone), one to place the chestnuts in and one for collecting the outer crusts instead of throwing them on the ground. AND he gives you a lemon-scented hand wash for after! AND he works from an old triporteur car where he keeps his chestnuts under a wool blanket while they wait...for me!
