Hermes Rodeo Pegase PM Charm Milo Lambskin and Swift Calfskin Vert Moyen Ardoise Vert Peppermint H083010CACU

Slate grey and two greens — a deep one and a bright one — make this Pegase the most architectural of the family. Up close you can read the layering of the tones; from a metre away it becomes a single moody green with one lit edge. Both readings are good ones.

The materials are the usual pair, Milo lambskin and Swift calfskin, with the grey-green areas velvety-soft and the peppermint flashes smooth and slightly brighter. Metal: none. That keeps the charm light in the hand and considerate toward whatever it hangs from.

Roughly ten centimetres at its longest point and eight across, it drops into a jacket pocket when a plain bag is required and comes back out for the weekend. The slim profile means it presses flat against a strap rather than flopping away from it.

Which bags suit it best: this is a charm for leather with a straight face — grained navy, charcoal, black or deep green. On a navy briefcase the slate blends in and only the peppermint edge catches the light; on a black weekend bag the whole arrangement reads like a small, exact model of itself, and I mean that fondly.

An honest note on composition: at this scale a three-tone design can look busy on a patterned bag. The slate-and-greens combination needs a solid backdrop to breathe — on grey, navy or black leather it looks intentional; over florals or logo-heavy canvas it is one story too many.
