If you don't have the constitution to spend your weekend hunting through army-navy stores for something vintage, here's an easy, throw-and-go military-inspired jacket to layer with everything you own. It's made of lightweight Harris Tweed, which is a super-special heritage textile from the Outer Hebrides that's by definition hand-woven on a treadle loom in the weaver's own home. (It's regulated by Scottish law.) Only a select few craftsmen are certified for this, and most come from families that have been weaving for generations. Casual jacket, special cloth.
Content + Care: 100% wool. Dry clean only.
