Mindshift Backlight 26L v 36L Bags

I'm currently looking for a new camera backpack as my current bag no longer fits everything I need to carry, especially my outer jackets and tops.
Whilst I'm confident, from the many other reviews I've seen of the Mindshift bags, that either the 26L or 36L bags will satisfy my camera gear needs, I'm not as certain about their ability to carry my outer clothing, comprising an insulated jacket, a rain jacket and maybe a thin fleece. So I bought both in order to have a closer look, with the intention of sending back whichever didn't meet my needs.
Both bags share the same basic design principles, the only difference being in their physical size and the amount of kit they can carry. So in this video I compare them primarily for their carrying capabilities.
I could find a use for either, or both bags, but which will I keep?
Both bags bought and paid for at my own expense.
