"Good, comfortable, convertible pack" - Review of Eagle Creek Switchback Max 25 Convertible Pack

After much research, I bought this pack for a 4 month round the world trip which will be made up of trains, planes, boats, islands, city hotels, and everything in between. I think this does lean towards the smarter, more stylish look, and I don't think i would rough it too much with this pack. I decided on this one because the waist/chest strap is very sturdy/comfy so for the short jaunts that I'll be back-carrying it, it'll take the load off. Easy detachable backpack - also looks good on it's own. Only fault would be no pockets in the main compartment.
