Don’t let the rising mercury fool you into thinking your summer wardrobe is complete without ample outerwear. The inevitability of temperamental weather and cool evenings calls for a lightweight summer jacket that you can throw on over any ensemble.

What is a summer jacket?

A seasonal staple, the summer jacket will provide just the right amount of warmth whilst enabling sufficient air circulation, making it a must-have throughout the warmer months.

Typically unlined and crafted from breathable cotton or linen, it tends to take a loose-fitting, unstructured silhouette. Examples include overshirts, chore jackets, denim jackets and coach jackets as well as lightweight raincoats, gilets and – for those more formal occasions – linen blazers.

The summer jacket’s lightweight nature makes it perfect for layering year-round: wear yours as a transitional piece in spring and over a sweater or under a coat when the weather cools. Think of it as an investment – such versatility and timelessness will guarantee a low cost-per-wear.
