Men's lightweight jackets

Men's lightweight jackets fill the gap between a full coat and no layer at all, built for the part of the year that's cool rather than genuinely cold.

Fabric and packability

Built from a technical shell fabric or a lighter cotton blend, the jacket is designed to fold down small enough to carry rather than wear the whole day, useful for a temperature that shifts between morning and afternoon. A showerproof finish on the outer fabric handles light drizzle without the bulk of a heavier waterproof jacket.

When a men's lightweight jacket earns its place

Spring and early autumn are where a lightweight jacket does the most work, layering over a shirt or jumper without adding the visible bulk a heavier coat would. This transitional role is exactly why Hackett London keeps lightweight styles in rotation across its outerwear range every season rather than treating them as a single-purpose piece.

Can a lightweight jacket be worn in the rain?

A showerproof lightweight jacket handles light rain well, though it's not built for sustained heavy weather in the way a fully waterproof jacket is.

What's the difference between a lightweight jacket and a gilet?

A lightweight jacket includes sleeves and offers more all-round coverage, while a gilet is sleeveless and designed purely for core warmth without restricting arm movement.

Is a lightweight jacket warm enough for winter?

A lightweight jacket is generally better suited to spring and autumn than deep winter, where a heavier coat or insulated jacket provides more reliable warmth.
