Have other Kipling bags; very good quality, last forever, would buy again.  Have a similar backpack that s about 10 years old and take it everywhere. It's a perfect size, a little larger than a purse but smaller than the usual backpack.  Holds water, camera, wallet, etc.  Very light weight but when it gets too heavy if we are out walking for a long time, I can always have my husband carry it as it's not a pocketbook.  I usually carry it on my shoulder not my back but it's comfortable either way.
