The Ecorce is an amazing colour, it translates to bark; it reminds me of a bar of milk chocolate.
IMO the leather varies from each bag, you can pick up two of the same style, colour and from the same season and the leather can varey considerably so if you can have a feel then do so before you purchase. The Ecorce bags I have looked at IRL have very chewey and thick leather, to be honest I have been blown away by the quality of the leather.
Anyway enjoy searching for your first one; the day is a great bag.
