Shifting skies on city nights? Zip up the Women's Mercer Jacket. Its 2-layer Marmot MemBrain® fabric repels water, while 700-fill-power down—finished with a moisture-resistant Down Defender treatment—keeps you warm. The hood with a single-pull adjustment offers extra coverage if you need it and removes when you don’t. Stow commuting essentials in the zippered welt or interior pockets.
