I'll bump this one. I've been using my iGig double pretty much weekly for a couple years now, and it's a GREAT bag with a TON of storage space. No other bag has this much pocket room. When I've got mine fully loaded, I can carry two basses and straps for both, my Shuttle 6 with power and two 6' Speakons, my iPad and page turner, and instrument cables in the 2nd (back) front bottom pocket. Also ear plugs, pens/pencils, business cards, a cleaning rag, and miscellaneous snacks for long gigs.
I've even used the second bass slot for clothes and stuff, eliminating a duffle bag for a recent short weekender gig.
These bags are quite well built, too... Mine has held up well after two years of use. The zippers all still work perfectly, none of the seams have come apart, and the bag takes abuse pretty well (within reason of course, I wouldn't purposely throw it down a flight of stairs...
If this was a single, I'd snap it up in a heartbeat. Got the double already!
