used this for my last holiday and it was perfect. i've heard that ryanair are a bit funny with sizes but it fitted great and even had space. it was more than big enough for my handluggage. i even took a change of clothes in it along with a very big book and there was still plenty of space. plus the pockets at the front were perfect for keeping my passport and tickets
Chose this for a flight on easy jet because I heard they were strict about bag size and also weight. This item fits the bill providing a really good strong cabin bag that can hold a deceptive amount of stuff!
