Picked this up as i travel with work a lot and this was to replace my long time suffering 'week-long' bag.
It practically swallows up anything i try and fill it with everything i need to take, it holds the contents very securely with the internal and external compression straps, the outside pockets I only use for kit i need quick access to such as paperwork / headphone storage / phone chargers but there is loads of room for more.
im most impressed with the wheels, although I haven't clocked up that many miles so far, the wheels are well protected and not too noisy, for going up stairs I really get spoilt with which handle to grab!
I was between this model and the 26" or a dakine but for the size gained against the cost it really was a no brainer for me.
