You swear by your Free Swingin’ Flannel Shirt for its lofty warmth and limitless comfort. Now your best four-footed friend can foray into the outdoors in a shirt built as staunchly as yours. We’ve used the same hearty 5.6-oz. 100% cotton that’s brushed twice for extra fluff and softness, and given it a prewash so it resists shrinkage. The yarn-dyed plaid is every bit as bright and bold. And we’ve hidden a full-length hook-and-loop closure inside the button placket to make sure that dressing doesn’t turn into a wrestling match. We’ve even included a locker loop at the back of the neck, so you can keep it hanging by the door for expedited exits.
