There are flannels and then there are flannels. If you're not hanging out in some 85-degree bar trying to look hip, and you need a functional shirt that will keep you warm in the woods, there's The North Face Campground Sherpa Shirt. The "Campground" backs up its soft, 100% cotton exterior with toasty Thermolite® fill and faux-Sherpa lining so even though it looks like a simple shirt, it's halfway to being a sleeping bag you can wear. More shirt than you need for the coffee shop, this one is ready for the outdoors.
