I’d disagree with a lot of the above. IME theres a lot of difference between bags. We had a triple DT Swiss bag for years. Solid materials, some padding, but was sized for road wheels so wouldn’t take a 29er with a mtb tyre.
I’ve got some very flimsy, unpadded, bags that came free with a purchase of wheels from Funn-wheesl in Germany. Massively oversized – don’t know what they built them for.
The Evoc bags are a different class. They’re the right size for a modern mtb wheel and tyre, solid materials, decent padding, and best feature the plastic cap over the axle area which is where other bags get damaged and damage other things. They do a road wheel sized bag as well. The downside? like all EVoc stuff it’s very expensive.
