The present invention relates to a down jacket with a selectable outer shell, which includes: an urethane coating layer formed on an inner face of an outer shell for preventing exudation of duck down such that not only synthetic resin but also fabrics of various kinds capable of exudation of duck down can be applied; and a tape member formed on an inner face of an inner shell so as to form a compartment through a thermal adhesion at a portion where the tape member and the urethane coating layer meet together, thereby making a processing process easy. The down jacket with the selectable outer shell is made with double fabrics having an inner shell and an outer shell and a plurality of compartments formed by computing the inner shell and the outer shell and filled with duck down.
