converts from backpack to tote, and unzips to expand. hard to find this bag (I looked for awhile to find this!) I purchased it preowned and it had some prior wear to it (small rips on interior as pictured, some wear to exterior and bottom corners, some tarnishing to some of the hardware.) nothing that is very obvious until up close, but please note pictures and let me know if questions! I did make repairs to rips as pictured (sewed closed.) retail was $345. fast shipping!
