Think of this shirt-jacket hybrid as a next-level flannel: a sturdy, heavyweight flannel shirt with cozy Sherpa fleece lining. It’s for moments when a mere shirt is too thin, but a bulky jacket is too heavy. The May Flannel is just right. You’ll want to wear it everywhere, whether you’re on the mountain or hanging by the fire. Snap buttons up the front make it easy to throw on and off.
