I have bought plastic cases, and I have bought material cases.
Sad to say, but the airlines have damaged them both.
That being said, I think maybe the non-plastic cases would work if the clubs fit in snugly---as long as NO metal pieces on the golf bag are pushing into the material carrier.
I am going to try to apply tape over buckles, etc for my next trip; to see if me and the airlines can get the carrier there undamaged this next time.
