Does exactly what it claims. Holds enough clothes and accessories for a short break, unless you're Imelda Marcos, and being less than 1Kg allows more clothing to stay within the max. weight and dimensions allowance for Ryanair. I was, in fact, picked out for a spot check and passed without drama. Seems well enough made for cabin baggage but I wouldn't entrust it to the baggage handlers - it's no Samsonite. Has to be carried since there are no wheels but therefore there's nothing to intrude into the lugggage space and take up weight allowance. Can be carried rucksack style or as a suitcase. Soft sided so stuff can move around and crease but adequate internal straps and zipped compartments for various items.
