When it's chilly but you don't want a bulky coat, this sherpa-lined flannel shirt is your best friend. It's basically a shirt and a light jacket in one – the outer layer is a classic plaid flannel (made from a cotton-polyester blend that's soft and durable), and the inside is lined with thick, cozy fleece that traps heat. It's warm enough for cool fall days or layering under a coat in winter. Has all the classic shirt details: a spread collar, full button-up front, long sleeves with button cuffs, and a handy chest pocket. The fit is regular, so it's comfortable for daily wear. Comes in a bunch of classic plaid color combos like red-black, green, and black-white. Great for casual outings, running errands, or even as a business-casual layer at the office if your workplace is on the relaxed side. Machine washable for easy care. A versatile, warm layer that looks good and feels even better.
