Picked one up off Ebay a couple of weeks ago. Bloody good quality for teh brice! I bought teh smal one, and I can fit my lunchbox, keys wallet and a pair of shorts for work in there, plus have a bit of spare room. Well built, chunky zips, strong materials etc. Magnets are quite strong, has a carry handle for off bike excursions, waterproof cover for rain, map pocket and a small pocket in teh end for bits and pieces. I just thought it was a great little bag at a great price. Not too big for the Z, and wouldn't look out of place on many of the smaller bikes. Regards, Andrew.
