Flylow Womens Penny Insulated Flannel

It looks like a regular women’s flannel shirt, but—surprise!—it’s insulated and made from technical fabrics.

You know the well-loved feel of an old favorite flannel? We tried to bring that vibe here. Even better: The Penny Insulated Flannel comes with 40 grams of Spaceloft synthetic down insulation and a cozy taffeta lining to keep you warmer than a bulky sweater. You’ll wear this as a midlayer on backcountry tours and as your go-to road trip shirt.
