The word “flannel” conjures images of plaid lumberjack shirts and a broad array of stylish modern takes on classic tartan patterns. Plaid flannels are a popular go-to, but don’t overlook the much-underappreciated solid color flannel as an even more versatile workhorse. You still get that warm softness, but a solid color ratchets up how frequently you can happily pull it out of the closet. Ranging in looks that are still very rustic to some that are a bit more dressy, you can pull off a solid flannel on a casual day at the office or at the campsite.

Here are 5 solid color flannel shirts from some great values-driven brands.
