Hard Graft's sharp-looking new open-front knit blazer combines smart style with the comfiest possible fit. It's the kind of thing you'd get if you mixed a soft cardigan with a suit jacket, so it's great for a casual night in or at a dressier event elsewhere.

It's made from 100% virgin wool in a deep navy melange color — accented by dark gray marbled buttons — and with self-cleaning fibers throughout, so all you have to do is hang it outside in the sun to freshen it up again. For any deeper cleaning, keep it handwashed only.
