It is interesting to note that the gig bag I bought from Technote USA in Los Angeles, California area, has all chrome steel hardware and to lock on the shoulder strap you have to really push hard to open the clasp that then locks over the steel triangle. There is no way this one could come apart. The strap is adjustable for length and all nylon as the bag is also. I though it was an excellent price too.
I have looked at the Technics Bag and it is NOT fail proof. BE CAUTIOUS
