This is a VERY high quality gigbag, strongly recommended. It has thick 30mm padding and really tough exterior, I don't think you could get better protection from a gigbag - for total protection you need a flightcase such as a Hiscox, I have one of those too but its bulky for carrying to sessions or festivals, whereas this gigbag is light and has rucksack straps so very easy to carry. The handles are well thought-out too - apart from the rucksack straps there is a handle on the side for carrying like a briefcase, plus a handle on the top which is useful for grabbing it out of the boot of a car etc. Top quality zippers and decent pockets for storing your plectrums, tuner, spare strings etc.
I first came across Rockbag cases when I bought an octave mandolin online, it was shipped to me in the UK from the States in a Rockbag mandola gigbag (20635B), I loved that gigbag and now always check the Rockbag range whenever looking for a case for any instrument.
