Rolling backpack - with luggage passthrough/slide over handle?
Folks,
Wondering if this product exists - a backpack, that can roll, that has a strap/sleeve that will let it easily and securely slide over the handle of a larger rollaboard. Why? I carry a couple of *very* heavy laptops/equipment in a standard laptop rollaboard with a luggage sleeve, but trying to carry that via shoulder strap (even with fancy ones like Tom Bihn) is painful. Would much prefer a dual shoulder/otb system, i.e. a backpack, but need the rolling support for very long walks.
If you've seen something like this, much appreciated.!
