Looks pretty neat. Would come in hand in the sunny outdoor shows where it's a pain to view the screen properly. Now if it can fit a lappy and my Traveler...
Not sure how big a traveller is, but the expandable pocket on this thing looks to be good enough to hold a firebox, ua-5 or usbpre... not sure about having your whole rig in there though.. mics, cables and all. Might run out of room pretty quick. I just ordered one and will try and get a good setup going. Most likely it will be used along with my nova 3.. which still won't be too much to lug into shows.
