The warmth in this collection comes from the lining and the collar. Shearling and faux-shearling linings hold heat through the body, while fur and sherpa collars keep the wind off your neck. Viscose-lined styles with a fur collar are lighter for milder days. Most jackets are cut in genuine leather, with faux leather, suede and cotton options. A lined jacket wears a little smaller than an unlined one, so if you will layer a knit underneath, consider the next size up and check the measurements on each product's size chart. Brown and black lead the range, with blue and green styles for a less expected look.
