Does the top loader on this pack detach to be used as a day pack?
Not easily. The top lid does float for large loads, but detaching requires a lot of unthreading straps. There's no included hipbelt on the lid, and no means of using the pack's hipbelt. Since these toplid-to-daypack conversions never carry well anyway, you'd be better off just carrying a very light small rucksack for this purpose.
