Moncler Grenoble's 'Guyane' jacket is part of the label's 'Performance and Style' line - the brand believes you shouldn't have to sacrifice one for the other. Cut from water and wind-proof shell, it's filled with insulating down and trimmed with black jersey along the arms and sides for comfort. The detachable hood is sure to block out the cold, while the belted back keeps the silhouette flattering.
