The lightest of its kind, well built, generous lengths of good velcro, no side boards to limit the usable real estate (which, for the avoidance doubt, is a good thing).
The bag, while also light and solid, stands out with the lack of any external compartment / pocket (which, for the avoidance of doubt, is not a good thing, as you have to fit any kind of accessory, like your power supply's power adapter, instrument cables or what have you, in the same compartment as the effects ... or elsewhere). Given the price is substantially higher than the immediate competition (Palmer, Harley Benton ...), I think this is something Pedaltrain could (and should) afford to add in the future.
