For the last couple of years, I've unsuccessfully been looking for the perfect summer jacket to travel in. The lighter jackets I use at home, my favourite is black but I would never wear black abroad. Another two are linen, not what I'm looking for to travel in. I'm too old for a denim jacket, though I've seen some quite nice ones in summer colours. Likewise, I don't wear blazer-style jackets. I ideally want something smart for the airport but can be carried in my daysac. Over to you, MN!
