Great protection for valuable guitars
This bag is extremely well made, it's as good as the description says it is. I use a rare Langcaster guitar as my main gig guitar and it just felt to loose in the Mono bag that I had. This bag to my surprise is a hair better than the Mono (in my opinion). It is very comfortable as a backpack. If Mono has any edge over this bag it might be in versatility of compartments, depending on the types of items you carry in bag.
I wouldn't throw my Langcaster off a building in this bag,,, but I will feel better when it's in the hands of a roadie or when all the overhead compartments are full and the flight attendant tries to get me to check it in.
Oh yes, the only reason that I didn't give it 5 stars is because it has a little Fender logo on it, and I don't endorse Fender.
