I agree with Aggie - and have used a backpack style for going on holiday where I did not often need easy access to the contents, but maximum capacity, then changed over to a smaller lightweight crossbody- with passport, purse, tissues, phone - for daily use.
I also no longer use a backpack one when I go to London as I need easy access to my travel card/bus pass without opening the whole bag.
For me the solution was to drastically pare down what I carry on a daily basis and take an additional (usually linen) bag if I am on a day out requiring bottle of water, umbrella, ipad or paperback.
It’s taken a while to wean myself off a full (and /or heavy) bag and I miss much-loved bags of the past such as my Cambridge satchel cross body simply because, even empty, , it weighed a ton!
