Moncler has increased its presence in the U.S. as well. As with any popular fashion item, the consumer risks purchasing a fake Moncler jacket. Some unscrupulous dealers and auctions, both live and online, sell counterfeits. Look for an authentic Moncler label at the center top of the inside of most Moncler jacket. For reversible and K2 styles, look for the label on the lower right inside of the jacket. Locate the size label directly beneath the Moncler label and confirm that the colors of the labels match. Confirm the location of the material-care label on the left portion of the inner part of the jacket, sewn into the lining seam. Look closely at the buttons and zipper of the Moncler jacket .
