Linen is a warm weather material. We all know this.
Lightweight linen trousers on the beach, loose linen shirts on a patio with a cold drink-- we can all picture these wonderful scenarios, and it's hard to do so without seeing linen. However, hear me out: I think there is definitely a place for linen during the winter months too. The texture of a thicker, flecked linen looks and feels very similar to some wools, and when heavier, can more than sufficiently warm you up.
For instance, Angelee and I have a dark grey linen duvet cover that we use exclusively in the winter. We tried sleeping with it during the summer, but I woke up sweating it was so warm (making it perfect for a winter night with the heater turned off).
Now take this jacket as an example. Its earthy green color allows it to span all seasons, its light weight makes it perfect for spring/summer, and its texture is not unlike all my flecked wool trousers. For today's look, I layered it with a medium weight sweater that's easy to shed in the event the temperature creeps into the 70s by the afternoon (now, could you imagine that happening?)
