The Women"s Hi-Q Luxe Jacket is constructed from lightweight, windproof fabric, with a Down lining that is supremely comfortable next to the skin, highly breathable and fast drying. The micro baffles are filled with premium Primaloft Gold Luxe synthetic fill which combines the loft and fill power properties of down with fast drying warmth of traditional PrimaLoft insulation. Best of both worlds. It"s quite common for synthetic jackets to not have a baffle construction, allowing the fill to spread throughout the jacket. By having the micro baffles, the fill will stay in all the areas so you"re not left with cold spots. Plus, we like the styling of them. Overall, a great alternative to down and not bad for the weight either
