This is a really good quality bag as you would expect from Givi. Previously used a 6l version which was a bit small but this 15l size has a really useful storage capacity without being too large. The tanklock system is excellent and so quick and easy to use compared to a magnet attachment and doesn't touch your paintwork. The bag has an internal waterproof drawstring liner which is a bit annoying and gets in the way, I dont know why it is there considering it also comes with a waterproof cover. And the map holder has a velcro attach which is fiddly to use with gloves on but you can remove it and use the other plastic window on the main bag. So loses a star for this but is generally an excellent bag.
