I've bought 5-6 gigbags from this line in the last 15 years, they are great for your secondary instruments, for storage or light travel.
If you use them as your main ones, their straps and handles WILL break within 3 years and within 6-8 years the internal "fabric" will actually disintegrate even with zero use (depending on humidity and temperature).
Surprisingly enough, the zippers on these things are very durable, I don't recall having a single zipper go bad on me (ok, of course every single zipper handle got ripped off within the first months, but that costs literally nothing to replace with anything).
So, these gigbags are great for people with a lot of guitars and already another, proper gigbag for actual transporting them, and are looking for something cheap and expendable for storage or light transport.
