Highland Tech Flannel - Sierra Wave

Free Unlimited Returns & Exchanges
Technical mid-layer disguised as a classic flannel.
We blended performance polyester for the trail with soft-touch rayon for the cabin, adding just enough spandex so it never holds you back. This shirt looks like a heritage flannel, but it also functions in the backcountry.
