We made the water repelling Randonnée Jacket with stretch trim at the wrists and hem because keeping air inside your cold weather gear is one of the best ways to save energy and warmth. Its stitched channels are filled with Dexfil 160 insulation. Additional elements like the inner Metal Heat panel near the chest give the Randonnee jacket even more heat-optimizing qualities. We incorporated stretch fleece side panels that extend up and under the arms into the design to help evacuate heat and improve freedom of movement. (This jacket can be embroidered with a custom logo on the upper back.)
