JOHN ROCHA / DESIGNERS AT DEBENHAMS. Distressed brown (lighter photos show the patina/colour best, but it is a tad darker - more bay than chestnut). I'd say best fit 42 chest but will fit larger.
Please see measurements: 24" Armpit to armpit, 19" shoulder to shoulder. Weight soft leather - some distress (most by design) all makes for an amazing patina.
