Convenient for commuting
It's not the most comfortable to wear as a backpack but not too bad. It's great for getting weight off your back while riding and still being able to carry stuff a short distance from the bike rack to your desk. The hooks go on to the carrier rack very easily and there is a velcro strap at the bottom to stop the bag from bouncing around while riding. It's a bit fiddly to do the velcro every time putting the bag onto the rack or taking it off, depending on the load it might not be needed. The capacity is quite a bit less than my old backpack but I've managed to jettison some things that I was carrying every day but don't actually need.
