I had this Timbuk2 messenger bag, with a phone case that worked until my Jolla arrived. The 3 way phone case is not for sale in Europe, or at least I couldn't find it, so I ended up ordering a new messenger bag and phone case. Certainly not cheap, freight and customs already cost 50 euro. But the old bag and phone case survived intensive use since 2000!

The inside of the phone case is made of velvet and fits wonderfully. The phone case is mounted on the sling of course for access while on bicycle.
