Flylow Women's Size Chart:

Regular Fit: A traditionally cut fit that sits comfortably and true to size. Not too baggy; not too tight. Right down the middle. This standard fit allows for plenty of maneuverability in a classic, everyday shape for daily life and active missions.
Relaxed Fit: Our most generous fit, which hangs in a flowy, roomy style that offers a relaxed comfort and total freedom of movement. This fit is free of constraints but still retains shape, structure, and clean design.
Slim Fit: This athletic styling offers a low-profile, contoured fit so that no extra bulk gets in the way. With ample stretch to retain mobility, this fit offers a slender and streamlined design for layering and on-the-go activities.
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.
