I have been in search of the perfect backpack since 1998. A needle-in-a-haystack find that’s not too big, not too small, durable, washable, in a color that that’s neither boring nor too loud, with zippers that don’t get stuck after a month’s worth of use, that makes carrying a laptop not lead to back surgery, and that doesn’t cost more than $50. This could be a very big day. For you too, if you’ve been on a similar mission to find a a scarf, a new graphic t-shirt, a geometrically patterned dress, or just aren’t into paying full price for things. The socially responsible, presumably made-in-Brooklyn, Urban Outfitters-meets-J. Crew lifestyle brand Brooklyn Industries will be offering “rock bottom prices” today through Saturday at their sample sale in their as-yet-unopened storefront digs in the former Mikey’s Hook-Up space on 70 Front Street in Dumbo. The early bird gets the worm with these types of things — doors open at 11am, close at 8pm — so may I suggest an extended lunch break today? Just lay off my backpack. RSVP to firstname.lastname@example.org is suggested.
