Truly an excellent product. I was very worried because I purchased a Thomann E-Bass Gigbag Premium four years ago, which ended up being a piece of trash (some months later it broke in different places). So I did not wanted to repeat the experience and I was looking for MONO cases, but they were too much money and not so many advantages. So I finally decided to take a chance betting for Thomann again. Man, this time I won the lottery!!!. I have a pretty heavy Fender Jazz Bass (American deluxe) and a lot of gear to carry on, and everything fits perfectly on my SafeCase 80, included 34 cms long mini pedalboard, which I made specifically for the Isothermal Storage Bag, which is also pretty sturdy. All in all, about 9 kilos.
I bought it all 4 months ago and just waited to see how it behaves, and now I can tell you, its just perfect, no signs of loose seams or tears like the previous one.
No problem at all with the position of the bag, access is just fine, and it is a big one.
