The bomber jacket
A bomber is the leather jacket for someone who wants to wear leather most days. The ribbed collar, cuffs and hem hold it close without structure, the zip is straight and the pockets are where hands go. It is the least formal of the silhouettes and the easiest to live with.
Why lambskin
The bombers here are cut in lambskin rather than cowhide. Lambskin is lighter, softer from the first wear and drapes over the ribbing rather than standing away from it, which is what gives a bomber its shape. It marks more easily than cowhide and it is not the leather for a motorcycle; it is the leather for a jacket that is put on and forgotten about.
Fit and layering
A bomber is cut with room for a jumper. The ribbed hem should sit at the waist and the cuffs at the wrist; the body has ease, the shoulders should still be your own. Take your usual size unless the product's fit note says otherwise.
When to wear it
Spring and autumn, over a t-shirt in the day and a knit in the evening. For the coldest months look at the shearling pieces, which are built for it; a bomber with a heavy jumper under it loses the line.
