My first impressions of this bag are amazing!
The build quality is superb, everything feels solid and built to last, all the padding and HeadLock system are very reassuring, the straps and handle feel really comfortable, and the storage space is quite generous for such a slim bag.
Personally, I bought this bag for occasional short/medium distance trips on public transports, by car or by foot, and not so much for travelling or gigging. Just wanted proper nice and solid protection for my bass.
I decided to go with the M80 instead of the Vertigo just for the added storage.
The big pocket can fit a nice pair of headphones, plus some mini pedals and cables. The top pocket is perfect for a clip-on tuner and other smaller accessories, including tools. And as the owner of a bass with an angled headstock, the HeadLock is a blessing!
TLDR: Great build quality, great padding, HeadLock system works like a charm, storage is more than sufficient, well balanced when using the handle, comfortable to wear as a backpack. If you're looking to get it, do it and you won't have any regrets!
