As small and portable as it is, I'd say it wouldn't fit in a gig bag pocket. It's 13 x 8 x 20cm and weighs 1.5Kg.
When I travel light to gigs I have a small backpack for my Sumo & leads, a bass in a gig bag in one hand, and my Metro16 Stomp board in a soft case in the other hand. Easy. If I'm driving it's the same, just with my cab too.
