PennyS I find Tilly endurables much better than Rohan, they are, unfortunately , very expensive, but are very hard wearing and durable the trousers have 6 velcro fastened pockets and have a concealed pocket inside the ordinary right hand pocket closed with velcro suitable for bank cards and paper money and is not noticeble to an inserted hand (ie Pickpocket)
I would be very interested in seeing any Santorini pix!!
