some of the gig bags on the market give as good as or maybe better protection than a stock martin hard case
I bought one of these for my 000-15. Fits it perfectly. https://reverb.com/item/9687730-ibanez-powerpad-541-series-ac-guitar-bag-moss-grn
Reunion blues or Mono. I went with the Reunion Blues for my dread naughts, just liked it better and so far ( about a year old) it's held up well. Great padding and exoskeleton. They should make one for most sizes
One is not going to get a light weight soft case that has any protectionHowever, the Continental cases are NOT light weight
