Brought this bag to carry my Liteloc X1 and Oxford Alpha XA14 Alarm Disc Lock, to save having to use a rucksack on commutes and rides. Liteloc X1 fits inside well and there is still plenty of roof for other items. Zips are good quality and it was easy to fit. With the net pocket and Velcro retaining strap inside this is a better quality product than I expected for the price would recommend.
