Hermes Bolide 27 Bag Handmade In Epsom Calfskin Leather Silver Hardware 2z Blue Nuit

Bleu Nuit is the most double-faced colour in the line: in lamplight it is black with a secret, in daylight it is a deep marine blue with ink in its blood. On this Bolide 27 in Epsom, the shift happens gradually enough that you notice it the way you notice good tweed — in fragments, over a day.

The bag itself is the standard twenty-seven centimetre dome — twenty-seven wide, twenty tall, ten deep — in heat-embossed calfskin that keeps its geometry regardless of load. Day-kit capacity: wallet, phone, keys, a pouch, sunglasses and a paperback for the commute. The dimensions do not stretch to a laptop or an A4 file, and I would not ask them to.

Silver hardware suits the cool register of the colour, and the zip runs the full width with a leather pull that is easy to find without looking — a small thing you appreciate on a wet platform with full hands.

Honest notes, three small ones. The blue only shows its hand in daylight, which surprises people who order navy expecting navy on their sofa at night. Second, dark Epsom is nearly scratch-invisible, which is a strength, but it also shows dust sitting between the grain with a certain honesty; a weekly wipe deals with it. Third, silver plus navy is a cooler pairing than some wardrobes built around gold jewellery take to — check your habits before committing.

If your colours run cool, this is as quietly right as a navy blazer, and it will outlast several of them.
