I have been pretty satisfied with this gig bag. I usually carry it on my back and use public transportation so the light weight was most important for me. It has also offered enough protection so far. The other reason to get this model was that the side compartment is big enough to hold sheet music.
The straps are not attached to the bag as seen on the pictures. They are removable but I would have preferred attached ones, now the bag is sometimes hard to put on since the straps twist. The quality has been otherwise good but the holder of one of the zipper sliders broke. I was able to attach a keychain ring to the slider. The broken part had contact with the ground often, I suspect that's why it got broken.
When the bag is empty it usually tumbles on its side. With this bag I need to keep my neck and mouthpiece in separate pouches. These features make the bag a bit unpractical at gigs if there's not enough room to maneuver.
The bag has worked pretty well but next time I would probably choose a bag that opens like a case.
