This is a well-thought-out product, and it feels like a lot of experience with inferior gig bags went into designing this.
It will keep your guitar stable inside the gig bag with the neck support, and the padding is thick enough to protect it from bumps or slighter drops. The zippers are strong and won't just open or come undone on their own, and even if they somehow would, the guitar would still be held in by the strap over the neck support. That said, I wouldn't put it in the cargo hold of a bus in this, let alone an airplane. It's a gig bag, not a hard case.
It has pockets for the back straps and a long shoulder strap that you can also detach, and you can hang on a wall by a D buckle. The straps are padded and make it comfortable to carry, even if you're lugging around a resonator acoustic or two of these at once.
The three additional pockets are quickly accessible and have sensibly differing sizes. Well suited for storing your odds an ends, and there is even space for an A4 notebook, something anyone should be able to appreciate.
Unfortunately, the faux leather material on the outside isn't particularly strong and will tear if it, for example, catches a door handle. This happened to a clumsy friend of mine, and not me. No. I had a problem with the thread unraveling on the zipper, but Thomann replaced the gig bag upon seeing the photos of the defect.
I'd be concerned with having less protective padding and features than this has and annoyed by worse straps, so I'd recommend against buying cheaper. On the other hand, I'm not sure if the benefit of a better gig bag is worth spending a lot more on it. I feel that this one compares favorably to pretty much any other you can buy for under 90¤ or so.
This is the one gig bag I see around on the streets most, and for good reason. I now have two and feel that this is a good compromise between guitar protection and carry weight for urban commuting. This should be your first stop for buying a gig bag for entry-level to upper mid-range guitars.
