Jack Frost won’t quit his relentless nipping? Armor up with Isis’s trio of frigid-weather gear, which is lightly lofted with natural down for insulation. (The asymmetric quilting veers you away from Stay Puft Marshmallow Man territory.) Sheathed in 100 percent post-consumer recycled polyester, the Whisper hoodie, jacket, and hooded vest pack a one-two-three punch of coziness, with extra features like velvet-lined chin guards and zippered hand-warmer pockets for good measure. Another bonus: 10 percent of sales goes to the Breast Cancer Fund. Consider the cockles of our hearts warmed.
