With my band we're starting to record more so I needed a ways to transport a few bits of home studio kit safely from my house to our practice space. This bag allows me to house my Focusrite Octopre and 18i20 interface. I bought the 3u to leave space, perhaps, for a headphone amp later.
The bag is made of tough-looking nylon. It seems to be reinforced with hardboard or ply. It it as light as is reasonable for the level of protection and I expect to to last at least as well as other bags I have made of similar material.
Access is from both ends, making patching cables easy. The price on Thomann was very good, much cheaper than similar products I could find online in the UK, and so it's more than met my needs.
