Until now, outdoors companies couldn't figure out how to make a stretchy puffy without down escaping. Mountain Hardwear solved that problem with a groundbreaking, stretch-welded construction that baffles the light and lofty down together in a stretchy, stitchless construction. Since it doesn't have stitches, the Women's Stretchdown DS Hooded Down Jacket offers far better protection--as well as mobile performance--compared to standard puffy jackets. That gives this puffy an advantage for skiers, alpinists, and backpackers, but that doesn't mean it doesn't look good in the city come wintertime.
