This is pretty well made, and generously sized for the La Mancha Rubi S/59 which I bought it for, perhaps a tad too big. It would be fine for those 3/4 guitars with scale length of 610mm. The material seems durable enough, and I imagine it would be shower-proof if not fully water-proof. There is a good sized pocket which will accommodate A4 books and music, and another that will accommodate a foot stool. Zips all seem sturdy too. 20mm padding should protect against most minor dings. Shoulder straps are fine as well. Bought this primarily because my son's favourite colour is red! Ultimately it's only a gig bag, which he'll use to take his guitar to school for lessons and concerts, so for that it's perfectly adequate. Happy enough with it.
