The name says a lot here. We often say that “a navy blazer can take you almost anywhere,” but that becomes a little trickier when it's raining outside or when the temperature dips below, say, 50 degrees. This is a classic, notched-lapel sport coat silhouette made up in a featherweight nylon from Italy and quilted with Cashpad on the inside, our favorite recycled cashmere fill. While it won't replace a heavy-duty parka or a heavy-duty raincoat, the nylon is naturally water-resistant and the Cashpad fill adds a nice layer of lightweight warmth. It's exactly the right move when you want something a bit more stepped-up than a field coat but not as formal as a topcoat.
