Hi everyone. A couple of months ago I looked at the large coach ergo pebbled leather at my local coach store and found it too heavy for me ( Ihave a bad/severe back-shoulder injury). I got the signature large ergo hobo which I love and find very lightweight. My question is this-I see on ebay some black smooth leather large ergo hobos, I believe from last season, and I wonder if the smooth or regular leather is significantly lighter than the pebbled leather or is it about the same? Thanks for all help in advance!
