Now that's a toasty flannel.

The Marmot Men's Arches Insulated Flannel isn't your everyday, "head to the bar," flannel. It has Thermal R insulation stuffed inside for increased warmth at cold campsites, on brisk hikes, or for winter casual. This flannel also uses a hollowcore construction to bring a surprising amount of warmth without the weight.

This insulated flannel is warm and comfortable. It fits more like a jacket so I don't like wearing it under a coat, but it is great as a top layer on cooler evenings.

Great flannel!

    Super comfortable and stylish flannel jacket! Lightweight with just enough insulation to keep you warm on a chilly night. Marmot never disappoints with their great quality clothing.

    Want a layer that is equally at home at your favorite pub as it is around a campfire? Well look no further.

    This flannel has a classic look and you're bound to get compliments anytime you are wearing it. The biggest plus however, is that this flannel is insulated and will keep you warm when most others won't.

    The insulation is just enough to keep you warm on a cool night around a campfire, or on your chilly walk to your favorite pub. The insulation is hardly noticeable, and doesn't make the shirt feel puffy or bulky.

    Typical Marmot craftsmanship here. You can count on this flannel to provide you with years of stylish warm for the cool fall or spring nights.
