i got my osprey farpoint 40 that i haven't used yet but i love how comfortable it is to carry. i fixed the no wheels issue by getting a little folding luggage trolley. i find it interesting that they put the detachable straps to the front of the bag. perhaps i'll put my on the front of the bag. gotta test this out.
Yeah agree with Seamus above, this pack is not intended to be carried in backpack mode long enough to warrant a waistbelt. Osprey actually has a great option for that with their Farpoint/Fairview 36L rolling backpack, I'd recommend checking that one out
I would love to get this bag, but if there was one thing I would ask you to consider in the future it would be a handle on the side so so it could be carried like a briefcase if necessary
