PB 0110’s navy AB 83 bag is made from vegetable-tanned leather that will develop a unique patina over time, which mirrors founder Philipp Bree’s belief that objects get more beautiful with each wear. It’s hallmarked with signature gold-tone metal accents on the top and opens to reveal a grey suede lining with a compact card pocket. Carry it cross-body alongside a sweater and voluminous trousers for a mid-week lunch.
