It's s utilitarian design classic, where style of the age meets design specs. Pocket design, collar shape and hide colour is always different. I got into A-2's from chancing upon a vintage G-1 in a vintage store in Brighton and being fascinated with the construction. The navy jacket is still my favourite, with more design and colour uniformity, but with subtle differences to catch the eye, the A-2 is the jacket that has become iconic. The simplicity and sheer style of something which has one purpose, as a uniform leather windcheater but the abundance of personalised artwork, attached stories and adventures which spans a vast period of time and history and historical interest which no other jacket quite does in the same way.
