I am about to fork out a small fortune for an osprey 70 litre backpack and I want to protect my new baby when I have to check it in on upcoming flights. I've been googling and a lot of the travel sacs out there seem to be pretty crap quality, only lasting one trip. Equally, the more robust duffle bags / military kit bags etc are just too heavy and bulky to have to carry around afterwards.
I have come across a few possibilites I may consider, so wondered if anyone has experience of these and could suggest which they think is best?

The last one seems to get a good few reviews, but since it is so light I am worried about it's durability and strength when lifted?
I know some people will say don't bother with a cover, just tuck all the straps in properly, but having had bags and even suitcases ripped & damaged in the past, I'm just not even risking this with a new expensive Osprey!
Thanks in advance
