How do they fit?
Mammut

Cut. Athletic, trim European alpine cut through chest and waist.
Marmot
Sizing. Take your usual size; only size up if you plan to layer a thick midlayer under a shell.
Cut. Regular to relaxed, layering-oriented American outdoor cut.
Sizing says whether to size up or down. Cut describes the intended shape. A deliberately roomy cut doesn’t mean the sizing runs large.
Neither quite right?
