New Leaf

I used their ebay shop to buy a givi top box and i it was fine - arrived very quickly and price was very good.

I got a bigger one than the one in your pic - i think its 45 litres, and it really is huge. On my commute to work it easily holds a suit, shirt, tie, shoes, towel and toiletries, all in a suit holder / weekend bag type thing. It would easily take a laptop as well but probably not in a carry case.

I take my laptop in a tank bag. You can get some quite smart tank bags that do not look out of place as a laptop carry case in the office.

Hope that help.
