I know, I know, talking about the weather is boring, but man oh man was it hot last week. For any man expected to endure the high summer sun in anything resembling business wear, take this as a plea to add an unstructured blazer to your warm weather wardrobe. Walking outside in anything else is just asking for a heat stroke.

A summer weight staple, the unstructured blazer comes without the lining and extra flourishes found in your standard blazer, for less weight and a lot more drape. The jacket follows the shape of your body, reading a little more relaxed and casual. Less fabric means less sweat.
