Bought 18 months ago, and probably never used for cycling due to change in jobs. The material is in excellent condition but has a couple of tiny marks, small amount of bobbling on the velcro - definitely not brand new.
Main roll top section is large. The fold over section at the bottom (intended for your camera equipment) is entirely separate - unfortunately I've misplaced the padded insert that would protect particularly fragile kit. The fact it's separate could be useful for wet/dirty kit.
Totally ridiculous sales video made for this bag not by me, but might answer any questions https://vimeo.com/59711050
It was £150 brand new, after £60 for it. Available to view in Clapham Common. I can show you the online invoice if you wish to prove it isn't moody.
