It was cheap, and i have like seven guitars hanging around the house. So i thought i'd give it a try and, in a worst case scenario, would just put it on the guitar i use the least (which is a light weight acoustic, incidentally).
However, it is much more comfortable than i expected, even with solid body bass guitars. In winter time anyway, when i wear it over at least a T-shirt AND a sweater.
Hence the title: 'Comfortable', cuz that was kind of surprising to me.
