So after a lot of thinking and looking around, I decided that my first Stowa would be a TO2. I first settled on a TO1 but before ordering I had a change of heart and wanted to go with a very basic but stylish design and the TO2 seems to deliver that best, in a contemporary way. I've specified the black leather strap as I'm really not sold on rubber but will probably try a few straps in the coming future.
I'll be back when the package arrives and will give you my first impressions. Exciting! I can see myself buying quite a few Stowa's in the coming months and years:)
