I love them, I don't use leather personally.
I have a large black, medium brown, brown patterned very large and small grey. That covers all eventualities 
The pockets and zipped compartments , the key tag , my very large one has a mesh pocket , brilliant for the carrier bags.
I do stick them in the washing machine , in a net bag (take the handle and the monkey off)
Some of the QVC viewers collect a millionty of the blighters .but not me.
I do have a zipped pouch for coupons and a zipped coin purse plus a card holder .I had a Brownie purse but I switched to an M&S purse with RFID
I've never seen any good ones in TKMaxx though .
I reckon you'd get bored with it before you wore it out .
