The thing to watch with the Evoc bag is that it’s heavy in itself, so you need to watch who you fly with. Jet2 had a 20kg limit when we flew with them, and if 8.6kg of that’s taken up with the bag then you’re likely to burst it. (though, in the end, they didn’t weigh our bags! Grr)
I can’t remember who made mine but it’s a pretty standard thing, sliders along the bottom, wheels at one end, straps all over, big zip. But is exactly the same size inside as a Specialized bike box, so I stuck one of those in it for armouring. Seems to work, and also makes the bag easy to maneuvre as it’s not flopping around everywhere.
